Use this GLP-1 insurance appeal letter template to write a letter that answers the exact reason your plan gave. That reason matters more than anything else you write. Medical necessity, step therapy, non-formulary, missing paperwork, and continuation denials each need a different response. A true benefit exclusion usually needs a different path entirely. Your written notice gives the filing deadline, destination, and process that apply to your case.

Here is the part most template pages skip.

For ERISA-covered employer plans, federal rules require the denial notice to identify the specific reason and plan provision behind the decision. If the plan relied on an internal rule, guideline, protocol, or medical-necessity judgment, the notice must include it or tell you that a copy is available free on request. Cigna's published weight-management policies include IP0206, IP0621, and IP0739. UnitedHealthcare's is Program Number 2026 P 1114-21. CVS Caremark's published Wegovy criteria are 4774-C and its Zepbound criteria are 6192-C. We've read those documents.

A letter that quotes your plan's own numbered rule back at it is a different animal than a letter that says "please reconsider, this medication is important to me." We built this page to help you write the first kind.

Best for you if

• You have a written denial for Wegovy, Zepbound, Ozempic, Mounjaro, or Foundayo
• Your letter says "not medically necessary," "criteria not met," "step therapy required," "non-formulary," or "missing information"
• Your plan ended a previously approved course before the authorization period or approved treatment count expired, or it denied a renewal and you need to document the plan's continuation criteria
• Your doctor's office is slow, busy, or unwilling, and you need to organize the patient side of the appeal yourself

Not for you if

• All you have is a pharmacy saying "not covered." That may not be a formal denial yet — see the first section below
• Your plan document truly excludes weight-loss drugs as a category. Skip to the exclusion section
• You expect a letter to change the FDA-approved uses of Ozempic or Mounjaro. It cannot. You may still have an appeal right under your plan, but the FDA-label issue needs its own strategy
• You want to put something in the letter that isn't in your medical records. Don't. It can end the appeal

Your deadline depends on your plan type. Start here.

Use the deadline and submission instructions printed on your notice, then compare them with the legal minimum that applies to your plan. Your notice tells you where and how to file; federal and state rules can give you more protection than a notice that is incomplete or wrong.

### Build your appeal letter — free, no email Choose the denial type, plan type, deadline shown on your notice, and the records you actually have. The builder creates a patient appeal letter, a criteria request, a records request for your clinician, an attachment list, and a deadline tracker. → Build my appeal letter Do not enter your name, member ID, diagnosis, chart notes, or a copy of your denial into the builder. It generates labeled placeholders so you can add identifying information after you download the packet. It will not invent a diagnosis, a lab result, a BMI, or a treatment you didn't try. That's the whole point.

What we actually verified

Checked at the source on August 5, 2026:

• 29 CFR 2560.503-1, including appeal deadlines, concurrent-care decisions, relevant documents, internal criteria, and full-and-fair-review protections
• 45 CFR 147.136, including urgent review, new evidence, deemed exhaustion, and federal external review
• CMS Part D redetermination guidance and the current CY2026 Part D appeals flowchart
• 42 CFR 438.402, 438.408, and 438.420 for Medicaid managed-care appeals and continuation of benefits

• Virginia Code § 38.2-3407.9:05 for state-regulated step-therapy exceptions
• KFF's 2024 Marketplace claims-and-appeals analysis, published March 24, 2026
• Published prior authorization criteria from Cigna, UnitedHealthcare, Highmark, and CVS Caremark named on this page
• Current FDA labeling for the drug-indication statements on this page
• Current public program pricing used in the late provider handoffs

What we did not verify, and can't:

• Whether your plan covers your medication
• Whether you meet your plan's criteria
• Whether your appeal will win
• The deadline and mailing address on your notice
• Any medical fact that isn't in your records

We'd rather tell you that plainly than pretend a template can read your chart.

Build your GLP-1 appeal packet

Answer capsule: The builder starts with the denial reason instead of a blank letter. It uses non-identifying choices to generate the correct patient letter, criteria request, clinician-records request, attachment checklist, deadline tracker, and red-flag scan. You add names, IDs, medical facts, and signatures only after download.

Step 1: Choose what happened

• Pharmacy rejection or "prior authorization required," but no written decision
• Missing or incomplete information
• Medical necessity or clinical criteria not met
• Step therapy required
• Non-formulary or not preferred
• Continuation or reauthorization denied
• Diagnosis or code mismatch
• Excluded benefit
• Experimental or investigational
• Quantity, dose, strength, or dosage-form limit

Step 2: Choose your coverage lane

• Employer plan — self-funded or fully insured
• Marketplace or other individual plan
• Medicare Part D or MA-PD drug benefit
• Medicaid managed care
• Medicare GLP-1 Bridge
• Other or not sure

Step 3: Enter only the dates and process details from the notice

• Date on the written decision
• Filing deadline printed on the notice
• Initial request, renewal, or coverage ended before the current authorization expired
• Submission method: portal, fax, mail, or another method stated by the plan
• Whether the notice identifies a policy name, number, criterion, or exclusion

Do not paste your denial notice, medical record, member ID, diagnosis, or free-text clinical history into the public builder. The output uses placeholders such as [member ID from insurance card] and [documented baseline weight from clinician record] so the tool does not need those details.

Step 4: Check the documents you actually have

• Written denial notice
• Plan criteria, formulary, Evidence of Coverage, or Summary Plan Description
• Prior authorization form or history
• Clinician letter
• Relevant chart notes
• Medication history
• Dated baseline and follow-up records
• Required exception or representative form
• Proof-of-submission method

Step 5: Generate the packet

The output should include all six pieces:

1. Patient appeal cover letter
2. Request for the plan's criteria and relevant documents
3. Message requesting clinician records or a medical-necessity letter
4. Numbered attachment index
5. Deadline and follow-up tracker
6. Red-flag scan that stops unsupported medical claims, missing attachments, false urgency, and exclusion cases routed through the wrong argument

Before generation, require this confirmation:

I will include only information that is documented in my records, stated in my denial notice, or confirmed by my clinician.

Wait — is this actually a denial you can appeal?

Answer capsule: A pharmacy saying "not covered" is not always a formal denial. It can mean the prior authorization was never submitted, is still pending, or was submitted with a missing field. A formal denial is a written decision from the plan, called an adverse benefit determination, and it comes with a stated reason and appeal instructions. Filing a long appeal letter when the real problem is a blank field on a form wastes the clock.

This is the step everyone skips, and it costs people weeks.

Prior authorization (usually just called a PA) is your plan's permission slip. A prescriber or the prescriber's office usually sends it before the plan will pay. When the pharmacy counter says "not covered," any of these could be true:

• No PA was ever sent
• A PA was sent and is still being reviewed
• A PA was sent with a missing signature, chart note, or code
• The drug isn't on your plan's covered list
• There's a quantity or dose limit
• It's too soon for a refill
• Your plan already issued a real denial and nobody told you

A written adverse decision gives you the reason and appeal instructions you need. If the problem is a missing or incomplete PA, correction and resubmission may be faster than a formal appeal.

Make this one call first

Call the number on the back of your insurance card and ask exactly this:

"Has a prior authorization been received for [drug name]? If yes, what is the current status, and has a written decision been issued? If a decision was issued, please tell me the date, the reason code, and where it was sent. If information is missing, please tell me the exact item."

Write down what they say. Get the reference number.

Fix it, or appeal it?

If the fix column describes you, a corrected resubmission is faster than an appeal. Your notice tells you which process applies.

Honest note: a polished letter sent through the wrong process can burn two weeks and answer nothing the plan actually asked for. It is an avoidable own-goal.

What should you look for in your denial letter — and what can you demand?

Answer capsule: For an ERISA-covered employer plan, a denial notice must give the specific reason and the specific plan provision behind it. If the plan used an internal rule, guideline, protocol, or medical-necessity judgment, federal rules require the notice to include that information or state that a free copy is available on request. Other plan types have their own notice rules, so use the appeal rights printed on your letter.

Most people read the denial letter looking for a reason. Fine. But the letter contains something better.

Thing 1: the exact reason, word for word

Copy it out. Don't summarize it. "Not medically necessary" and "does not meet plan criteria" and "excluded benefit" are three different denials with three different answers.

Thing 2: the plan provision they cited

There's usually a policy name, a number, or a section reference somewhere. It might be buried. Find it.

Thing 3: the rule they actually used — which you can demand

This is the part almost nobody uses.

When an ERISA-covered group health plan denies you and relies on an internal rule, guideline, or protocol, the notice has to do one of two things: hand you the rule, or tell you a free copy is available if you ask. If medical necessity or experimental treatment is involved, the notice must include an explanation of the scientific or clinical judgment applied to your case, or tell you that explanation is available free on request.

There's more. Under 29 CFR 2560.503-1(m)(8)(iv), "relevant" documents include a statement of plan policy or guidance about the denied treatment and diagnosis — whether or not the plan relied on it to decide your claim.

Use this request:

"Please provide, without charge, every internal rule, guideline, protocol, medical policy, clinical criterion, and statement of plan policy or guidance relevant to this adverse benefit determination, including any material applicable to the treatment and diagnosis whether or not relied upon in making the decision. Please also provide the specific plan provision and the scientific or clinical judgment applied to my circumstances."

Why this changes everything

These policies are specific, numbered documents. We've read a number of them. The table below compares sample published criteria; your employer or plan may use a different version.

Read those rows again. Four different BMI floors — 30, 32, 35, 40 — for the same category of treatment, in the same year, across three insurers. Two are from the same insurer.

This is why "I meet the criteria" is a weak sentence and "I meet criterion 2.b of policy IP0206, and here is the documentation" is a strong one. See Sources 17–20 below.

### Get the exact wording to request your plan's criteria The builder produces a short criteria-and-records request that names what you're asking for and cites the ERISA rule when that rule applies. Send it the same day as your appeal or immediately after you receive the denial. → Create my criteria request

The right GLP-1 provider isn't the same for everyone — it depends on your state, your insurance and formulary, whether you want an FDA-approved or compounded medication, your preferred treatment path (injection or oral), and your budget. Because a general answer can't resolve those for you, use The RX Index's Find My GLP-1 Path tool to get a personalized provider match with source-verified pricing before you choose.

→ Get my personalized GLP-1 path

How long do you have to appeal a GLP-1 denial?

Answer capsule: ERISA-covered employer plans and plans using the federal ACA internal-appeal standard generally allow at least 180 days. Medicare Part D allows 65 calendar days for a redetermination. Medicaid managed care allows 60 calendar days for a plan appeal, followed by a separate 90-to-120-day state-fair-hearing window after the plan resolves the appeal. The Medicare GLP-1 Bridge is a separate demonstration with no appeal process under the Bridge.

Four insurance lanes, plus one demonstration. Five different rule sets. Nobody tells you which one you're on.

Two things you should know about that table.

One: you'll see other sites say "you have 60 days" as a blanket rule. That's wrong for most of these lanes. Medicare Part D is 65 days. ERISA and federal ACA internal appeals generally allow 180.

Two: you'll see sites list Medicaid as "90 to 120 days." That's the window the state must allow for requesting the later fair hearing. The plan-level appeal itself is 60 days from the date on the notice.

The self-funded question, and why it decides your whole strategy

If you get insurance through work, your plan is usually one of two things.

Fully insured means your employer buys coverage from an insurance company, and that company takes the claims risk. State insurance laws generally apply.

Self-funded means your employer pays claims and hires an insurer or administrator to run the paperwork. KFF's 2025 Employer Health Benefits Survey found that 67% of covered workers were enrolled in self-funded plans. State benefit mandates and state insurance-department remedies often do not apply in the same way because ERISA preemption can block them.

Why care? Because state step-therapy laws, state external review, and your state insurance department's complaint process often reach fully insured plans and may stop at the door of a self-funded one. Same insurance card. Completely different set of tools.

How to find out in one question. Call HR or your benefits administrator and ask: "Is our health plan self-funded or fully insured?" Or read the Summary Plan Description and look for whether the insurance company is the insurer or the claims administrator. "Claims administrator" is a strong sign that the plan is self-funded, but ask the plan administrator to confirm.

A self-funded plan may still be subject to ERISA claims rules and, if non-grandfathered, federal ACA internal-appeal and external-review standards. Use the Summary Plan Description and denial notice to identify the exact process rather than assuming every state rule applies.

The 72-hour option most people never use

There is a fast track. It's called an urgent-care claim.

If an attending provider determines that waiting on the normal timeline could seriously jeopardize your life or health, or your ability to regain maximum function, the federal ACA urgent-care standard requires the plan to defer to that provider's judgment about urgency. The decision deadline is generally 72 hours, and the request can be made orally.

Two honest cautions. First, this has to be a real clinical judgment your prescriber makes, not a box you check because you're impatient. Second, "I ran out of my medication" is not automatically urgent. Ask your prescriber whether your situation genuinely meets that standard, and let them make the call.

### Put your real deadline in writing Enter the deadline printed on your notice. The builder adds it to the top of the packet, calculates follow-up dates from the plan's stated timeline, and warns you when a general rule conflicts with the notice so you can call immediately. → Add my deadline to my packet

How do you use this GLP-1 insurance appeal letter template?

Answer capsule: A usable GLP-1 appeal letter identifies the member and case number, quotes the denial reason word for word, requests reconsideration, points to each attached document, and asks for a written decision. It should not contain a diagnosis, measurement, prior treatment, side effect, or clinical conclusion that is not documented in the medical record.

No email needed. Copy it, edit it, send it.

Bracketed fields are labeled by where the information comes from. That labeling is deliberate. It's the difference between a letter that holds up and a letter that gets you in trouble.

[Today's date]

[Appeals department name and address, fax number, or portal — copied from your denial notice]

Subject: Appeal of coverage denial — [medication name]

Member name: [from your insurance card] Member ID: [from your insurance card] Case or reference number: [from your denial notice] Date of denial: [from your denial notice] Prescribing clinician: [name and phone]

I am requesting reconsideration of the decision dated [date] denying coverage for [medication name and strength], prescribed by [clinician name].

The denial notice states: "[paste the exact wording from your notice — do not paraphrase]."

I am asking the plan to review this decision using the information listed below.

The notice indicates that this decision was based on [plan policy name or number, if your notice gives one]. I am separately requesting every plan policy, clinical criterion, rule, guideline, protocol, rationale, and claim document that I am entitled to receive under my plan and applicable law. [If this is an ERISA-covered plan, insert the criteria-and-relevant-documents request generated by the builder.]

[Insert the paragraph that matches your denial reason. The builder writes this for you. It requests review and points to your evidence. It does not create evidence.]

I am attaching the following:

1. Copy of the denial notice
2. [Letter from my clinician, if available]
3. [Chart notes documenting the condition and treatment history]
4. [Documentation of prior therapies, if step therapy is at issue]
5. [Any form the plan requires]

Please confirm receipt in writing. Please provide your decision in writing to the address below. If any required form or document is missing, please tell me promptly and in writing so I can supply it before the deadline.

Sincerely,

[Your name] [Address] [Phone] [Email] [Signature, if the plan requires one]

This is a patient letter. It organizes your request and your evidence. It is not a clinician's medical-necessity letter and should never be presented as one. If your denial is about clinical criteria, you usually need clinician-supplied records, a clinician letter, or both.

The message to send your doctor's office the same day

Copy this into the patient portal or hand it to the front desk:

Subject: Records or letter needed for a medication appeal

My insurance denied coverage for [medication] on [date]. The notice gives this reason: "[exact wording]."

The plan appears to require [the specific criterion or document]. Could your office provide the chart notes, documented treatment history, or a signed medical-necessity letter that addresses that reason?

I've attached the denial notice and the filing instructions. The deadline on the notice is [date].

Please let me know whether your office will submit the material directly to the plan, or send it to me to include in my packet.

Short. Specific. Names the deadline. It gives front-desk staff enough information to route the request without guessing what you need.

What to leave out of your letter

• "This medication is guaranteed to work"
• "I meet all the criteria" — without going criterion by criterion
• "There are no alternatives" — unless your clinician documented that
• Any diagnosis, lab value, BMI, side effect, or failed medication that isn't in your records
• Any urgency claim your prescriber hasn't actually made
• A pile of study abstracts with no explanation of how they answer your denial

A study pasted into the packet without a connection to the denial rarely answers the plan's question. Identify the criterion it addresses and use clinician-supported explanation when medical judgment is involved.

What do you write, and what must come from your clinician?

Answer capsule: A patient can usually request an internal appeal without a clinician signing the patient cover letter. The federal rule requiring a qualified health professional to review a medical-judgment appeal governs the plan's reviewer; it does not turn the patient's letter into medical evidence. Diagnoses, measurements, treatment history, side effects, contraindications, and clinical conclusions still need to come from the medical record or a clinician who actually evaluated you.

You can drive this. You just can't be the doctor.

Three source labels to keep straight as you fill anything in:

• From your denial notice — reason, case number, deadline, address
• From your medical record or clinician — diagnosis, measurements, prior treatments, side effects, contraindications
• Your administrative request — what you're asking the plan to do

Never move an item from the second category into the first or third by guessing at it. If a number isn't in a record, leave the placeholder and ask your clinician for it.

The rules that make a careful clinical record matter more than you'd think

For an ERISA appeal subject to 29 CFR 2560.503-1:

• The appeal must receive a fresh review without deference to the initial decision, by someone who is not the original decision-maker or that person's subordinate
• When medical judgment is involved, the plan must consult an appropriately trained health care professional
• That professional cannot be the person consulted for the initial decision or that person's subordinate
• You can request the identity of medical or vocational experts whose advice was obtained, whether or not the plan relied on it

For plans subject to 45 CFR 147.136, if the plan develops new evidence or a new rationale during the appeal, it must provide that material free and early enough for you to respond before the final decision. The plan cannot save a new reason for the final denial and give you no chance to answer it.

If your prescriber won't help

It happens. Some offices are underwater. Some do not handle weight-management appeals. Some prescribed the medication in a short visit and do not have enough documentation in the chart to support the criterion the plan is asking about.

If that's you, the appeal may not be dead — but a different clinician cannot truthfully manufacture a history that is not in the record. Start by requesting your existing chart, the denial notice, and the plan criteria. Then ask a clinician who is willing to evaluate you what they can genuinely document and support.

### Find a clinician who will evaluate the paperwork problem Success by Sesame currently starts at $59 per month with an annual subscription; medication is separate. Sesame says the program includes video care, messaging, and insurance-paperwork assistance for insured patients. A provider still decides what they can medically support after evaluating you. See Source 23 below. → Check current Sesame program details Straight talk: this costs money your own doctor's office may not charge. If your office is just slow rather than unwilling, send the short portal message above, attach the denial, and follow up. Try that first.

How does the letter change based on your denial reason?

Answer capsule: The denial reason determines what the appeal must answer, what evidence belongs in the packet, and whether a letter is even the right tool. Missing-information cases often need correction rather than rhetoric. Clinical-criteria cases need clinician documentation. A contractual exclusion is not the same fight as medical necessity.

Here's the whole map. Find your row.

The FDA-label mismatch no letter can erase

Read this before you spend a week on paperwork.

Ozempic and Mounjaro are FDA-approved for type 2 diabetes and other uses stated in their labels; their labels do not include chronic weight management. Wegovy, Zepbound, and Foundayo have FDA-approved weight-management indications. No appeal letter can change those labels.

That does not mean an off-label commercial-plan denial is "not appealable." Plans can have their own off-label coverage rules, and a written denial may carry appeal rights. The honest question is whether your plan covers the prescribed off-label use under its terms and what evidence it requires. Under basic Medicare Part D, a prescription used solely for weight loss is excluded from the Part D benefit; an applicable Part D-covered indication is a separate coverage question.

The cleaner path may be a medication whose FDA-approved use matches the documented reason for treatment, if your clinician determines it is appropriate. The clinician makes that choice. A template does not. See Source 21 below.

Step therapy: your state might hand you a deadline the plan has to respect

Step therapy means the plan requires a preferred treatment first before it will cover the requested one.

State rules vary. Virginia's law for covered state-regulated plans requires a carrier to answer a complete step-therapy exception request within 72 hours, including weekends, or within 24 hours for an exigent circumstance. The Virginia statute does not say that missing that deadline automatically grants the exception. A missed deadline can support an escalation or complaint, but do not tell the plan you won by default unless your own state's law expressly says that.

Two limits. First, read your own state's statute and the plan's instructions rather than trusting a national summary. Second, state step-therapy mandates often apply to fully insured and individual plans and may not control a self-funded employer plan. Which brings you right back to the self-funded question above.

What changes if your coverage ends before the authorization does?

Answer capsule: Concurrent-care protection is narrower — and more useful — than a generic renewal rule. Under 29 CFR 2560.503-1(f)(2)(ii), if an ERISA plan approved an ongoing course of treatment for a defined period or number of treatments and then reduces or ends it before that approved period or treatment count expires, the reduction is an adverse benefit determination and the plan must give advance notice early enough to appeal and receive a decision before the change takes effect. An ordinary renewal after the original authorization expires is still appealable, but it is not automatically the same concurrent-care situation.

This is the section we'd bookmark if we were you.

If your authorization still has time or approved fills left and the plan cuts it off early, you have a stronger timing argument than someone asking for a new course of treatment.

One: the cutoff itself is appealable. Reducing or terminating an approved ongoing course before the end of the authorized period or treatment count is an adverse benefit determination, except when the change comes from a plan amendment or termination.

Two: the plan has to give notice before the approved course ends. The notice must arrive early enough for you to appeal and receive a decision before the reduction or termination takes effect.

For a plan subject to the ACA internal-appeal standard, coverage of an ongoing course cannot be reduced or terminated during the appeal without advance notice and a completed appeal process. Medicaid continuation is separate and has its own requirements, explained below.

What if this is a renewal after the old authorization expired?

That is still a denial you can appeal. It just does not automatically get the special concurrent-care timing above.

Renewal criteria are specific, and they're usually about the documented response to treatment. From the published documents we reviewed:

• CVS Caremark's Wegovy and Zepbound renewal criteria require at least three months on a stable maintenance dose plus at least 5% weight loss from baseline, with a 12-month approval period in the reviewed criteria
• Cigna's reviewed policies use at least 5% weight loss for many one-year renewals and 4% for liraglutide
• Highmark's "Standard" policy renews at 5%; its "Enhanced" policy uses 7.5%
• UnitedHealthcare's reviewed policy uses 3% for Qsymia, 4% for Saxenda, and 5% for Wegovy and Zepbound

And here's the trap that catches people: which weight counts as baseline. Cigna's reviewed policies define baseline as the weight before any GLP-1 treatment, not necessarily the weight before the current drug. If you switched medications, that can change the calculation.

Your renewal letter should show four things, in order: where you started, with a date; what you took and for how long; where you are now, with a date; and the exact renewal rule from the plan document. See Sources 17–20 below.

### Build the right version — early cutoff or renewal Choose whether the plan ended coverage before the current authorization expired or denied a new authorization after it expired. The builder uses the concurrent-care request only for the first situation and the renewal-evidence checklist for the second. → Build my continuation or renewal appeal

What should you attach to a GLP-1 appeal?

Answer capsule: The letter organizes the request; the attachments carry the argument. Include the denial notice, the plan's criteria document, clinician records addressing the stated denial reason, and proof of any prior therapies at issue. Label each attachment in the letter, and never list a document you haven't actually included.

Two habits that pay off. Number your attachments and reference the numbers in the letter. And keep proof of delivery for everything — a fax confirmation, a portal receipt, a tracking number. "I sent it" is not a fact you can prove. A confirmation page is.

If they say no again: external review

Answer capsule: After an eligible final internal denial, an independent review organization can overturn the plan's decision, and a reversal is binding on the plan. The federal filing window is four months, the standard decision comes within 45 days, and expedited review takes no more than 72 hours. The reviewer looks at the claim fresh and is not bound by anything the plan concluded internally (45 CFR 147.136(d)(2)(iii)(B)(5)).

An internal appeal asks the plan to change its own mind. External review takes it out of their hands.

Independent review organization (IRO) means an outside review entity assigned under the applicable state or federal process and subject to independence and accreditation requirements. The plan or issuer bears the review cost. A qualifying state process may charge no more than $25 per request, must waive the fee for financial hardship, refund it if you win, and cap fees at $75 for the plan year. The federal process is free to the claimant.

Three things that make external review winnable

It starts over. The IRO reviews your claim de novo — from scratch. It is expressly not bound by the plan's internal reasoning. So this is your chance to make the strongest version of the argument, not a rerun of the last one.

You get to speak directly to the reviewer. Once the IRO tells you your request is eligible, you have 10 business days to send additional information straight to them. Under state processes the minimum is 5 business days. Use it.

The plan can lose because it fails to produce the record. Once an IRO is assigned under the federal process, the plan generally has five business days to provide its documents. If it does not, the IRO may terminate the external review and reverse the adverse benefit determination. That is discretionary, not automatic — but missing paperwork can cost the plan the case.

You may be able to skip the internal appeal entirely

If a plan fails to follow the appeal rules, you're treated as having already exhausted internal appeals, and you can go straight to external review. It's called deemed exhaustion (45 CFR 147.136(b)(2)(ii)(F)(1)). Medicaid has its own version — if your plan blows its notice or timing requirements, you can head straight to a state fair hearing (42 CFR 438.408(f)(1)(i)).

A de minimis violation does not trigger deemed exhaustion when the plan satisfies the regulation's good-faith, non-prejudicial, and other conditions. You can request a written explanation of the asserted violation, and the plan must provide it within 10 days.

The one thing that decides whether external review exists for you

Federal external review generally centers on denials involving medical judgment — medical necessity, appropriateness, level of care, effectiveness, and experimental or investigational treatment — plus several other specifically listed categories. A flat contract exclusion is a different animal. State processes can be broader.

Practical translation: reading whether your letter says "not medically necessary" or "not a covered benefit" is the single highest-value thing you'll do today. One usually has an outside reviewer waiting at the end. The other usually doesn't.

Current alert — verified August 5, 2026

The federal external review process run by HHS has been temporarily unavailable since July 1, 2026 for certain people in Alabama, Florida, Georgia, Texas, Wisconsin, and U.S. territories other than Puerto Rico, when their plan uses that HHS-administered process.

If you're in one of those places, follow the destination printed on your final denial notice and check the current federal external review page before you file. Don't mail an appeal to an address you found in an old article. See Source 4 below.

How do Medicare and Medicaid GLP-1 appeals work?

Answer capsule: Medicare Part D gives 65 calendar days for both the plan redetermination and the request for Part D IRE reconsideration; a standard benefits decision is due in 7 days and an expedited decision in 72 hours. Medicaid managed care gives 60 days for the plan appeal and usually 30 days for a standard decision. The Medicare GLP-1 Bridge is outside Part D and has no appeal process under the demonstration.

Five levels, and the numbers are specific:

Those dollar figures come from CMS's current 2026 Part D flowchart and change annually.

The Part D clock trigger that matters. For a tiering or formulary exception request, the adjudication timeframe begins when the plan receives the prescriber's supporting statement, not merely when the patient asks for the exception. Confirm that the plan received the statement and write down the date.

A Part D denial can involve two different questions. First, is the drug prescribed for a medically accepted indication that Part D may cover? Basic Part D excludes a drug when it is used solely for weight loss. Second, if the use is coverable under Part D, did the request satisfy the plan's formulary, step-therapy, prior authorization, or exception rules? Do not collapse those into one generic medical-necessity argument.

Medicaid managed care

• 60 calendar days from the date on the adverse-benefit-determination notice to file the plan appeal
• Plan resolution within 30 calendar days standard or 72 hours expedited, subject to a permitted extension of up to 14 calendar days
• One plan-level appeal before the state fair hearing
• A state fair-hearing request window of 90 to 120 calendar days after the plan appeal resolution notice
• Deemed exhaustion can allow a fair-hearing request when the plan fails to follow the notice and timing rules in 42 CFR 438.408

The continuation rule has a much shorter fuse. Under the federal Medicaid managed-care rule, benefits continue only when all required conditions are met: the appeal concerns termination, suspension, or reduction of a previously authorized service; the service was ordered by an authorized provider; the original authorization period has not expired; and continuation is requested by the later of 10 calendar days after the plan sends the notice or the intended effective date. If the final decision is adverse, the state may allow the plan to recover the cost of continued services. Ask for continuation immediately; do not assume it applies to an expired authorization.

Medicare GLP-1 Bridge: there is no appeal under the Bridge

CMS says it in plain words: there is no appeals process under the Medicare GLP-1 Bridge.

What you do have is a correction-and-resubmission route. A prescriber may resubmit the prior authorization when the original submission contained incorrect information or when updated or additional information is available. CMS does not describe this as an unlimited appeal right.

As of August 5, 2026, the Bridge includes Foundayo, all Wegovy formulations, and the Zepbound KwikPen for eligible beneficiaries when used for the demonstration's weight-management purpose. It does not include Zepbound single-dose vials or single-dose pens. The Bridge operates outside the Part D benefit, and a beneficiary's separate Part D appeal rights remain intact for a Part D coverage determination. See Sources 6–12 below.

What if your plan just excludes weight-loss drugs?

Answer capsule: A true contractual exclusion means the employer or plan did not purchase that benefit, and a medical-necessity letter usually cannot create coverage that the contract does not include. Before accepting that answer, verify whether the denial reflects a genuine category exclusion in the plan document or a misapplied formulary, documentation, or clinical rule.

Here's our one hard truth on this page.

If your plan document genuinely excludes weight-loss medication as a category, a beautifully written medical-necessity letter usually won't create coverage that isn't there. We're not going to pretend otherwise to keep you reading.

But before you accept it — verify it. A denial notice can describe the problem incompletely or apply the wrong plan provision.

Check these four documents

1. Your Evidence of Coverage or Summary Plan Description — the booklet that lists what's covered and what isn't. Find the exclusion language and read it word for word.
2. Is the exclusion for the drug, the indication, the benefit category, or a pharmacy tier? These are not the same, and each points to a different appeal or exception question.
3. Is there an obesity-treatment rider? Some employers buy the benefit as a separate add-on.
4. Does your denial reason actually match the plan language? If the notice says "criteria not met" while the plan document says the benefit is categorically excluded, ask the plan to identify which rule actually controlled and use the appeal rights in the notice.

That last one is worth ten minutes of your time. From the policies we've read, "the plan excludes weight management" and "this drug is excluded" are different statements. Cigna publishes what it calls benefit exclusion override policies — rules for approving the drug inside a benefit that would otherwise be zero. If your employer bought one, an exclusion isn't the end.

Do not change the diagnosis

We have to say this plainly. Never ask a clinician to change or add a diagnosis to get around an exclusion.

A different covered use matters only when it's clinically accurate, documented, and actually applies to you. Wegovy has approved uses beyond weight management. Zepbound has one for moderate-to-severe obstructive sleep apnea with obesity. If one of those genuinely describes your situation and it's in your chart, that's a legitimate different pathway. In the reviewed CVS Caremark criteria, the non-weight-management pathways use different criteria and do not use the same six-month weight-management-program requirement.

But "genuinely describes your situation and is in your chart" is doing all the work in that sentence. Your clinician makes that call, not a template.

If it really is excluded, here's where to go

• Appeal anyway if your notice grants appeal rights, because the plan may have misapplied its own terms
• Ask your benefits administrator whether an employer-level exception or review exists — self-funded employers can and sometimes do make exceptions
• Contact your state Consumer Assistance Program or insurance department, if you're on a fully insured or marketplace plan
• Preserve the possibility of external review for an eligible denial involving medical judgment
• Talk to your clinician about a covered treatment path that fits you

### Get a fallback plan built around your actual situation If insurance is a dead end for now, that doesn't mean you're out of options — it means you need a different plan.

Do GLP-1 appeals actually work?

Answer capsule: We found no national public dataset that reports a GLP-1 drug-appeal success rate. The newest Marketplace transparency data combines post-service medical and prescription claims, excludes prior-authorization denials, and cannot isolate GLP-1s. In that 2024 dataset, fewer than 1% of denied in-network claims were appealed, and insurers upheld 66% of appealed denials — meaning 34% were reversed.

You'll see a lot of numbers on this topic. Here's where they actually come from.

That's not nitpicking. The current federal Marketplace reporting used in the 2024 KFF analysis does not include denied prior-authorization requests. CMS's current interoperability prior-authorization rule also excludes drugs from its specific-denial-reason requirement. A national GLP-1 appeal rate cannot be pulled from those datasets. See Sources 14–16 below.

One directly relevant published GLP-1 operational study

A 2026 study in the Journal of Managed Care & Specialty Pharmacy examined prior authorization work at UC Davis Health from October 2024 through April 2025. Weight-loss GLP-1 requests in that sample were approved 48% of the time, compared with 90% for diabetes GLP-1 requests. Weight-loss GLP-1 requests required 7.1 more minutes of staff time per prior authorization on average than diabetes GLP-1 requests.

Be careful with it. It was one academic health system, six pharmacy technicians, and self-reported time. It is not a national approval rate and it is not an appeal-success rate. See Source 15 below.

The number that actually matters

Across the 2024 Marketplace data, fewer than 1% of denied in-network claims were appealed at all. A separate KFF consumer survey found only 40% of insured adults believed they had a right to an independent outside review; 51% were unsure and 9% believed they did not. Among Marketplace enrollees, 34% knew about the right.

So the most defensible conclusion is not that most GLP-1 appeals win. It is that very few denied claims in the Marketplace dataset entered the appeal process at all, and many people do not know the outside-review right exists.

What the payer documents show about why packets fail

We cannot give you a national rate. We can show you what the published criteria repeatedly demand: proof of the exact baseline, proof of the required program or prior therapy, proof of the treatment response, and documentation tied to the policy's own wording.

That is why the boring part of this page — the criteria request, the dated records, the numbered attachments — matters. A persuasive sentence cannot replace a missing record.

And one real warning, not a testimonial

The Wall Street Journal reported in 2025 on patients affected by CVS Caremark's Zepbound formulary change. One patient's exception was initially denied and later approved after an appeal; another patient who had lost 50 pounds was required to switch medications. Those are individual outcomes, not an approval rate.

We include that for a reason. Appeals are not magic, and outcomes can split even under the same formulary change. Anyone who tells you a template guarantees approval is selling something. Even official manufacturer sample appeal materials say they do not guarantee reimbursement.

What we can honestly say is this: federal ERISA rules prohibit charging a fee as a condition of the internal appeal, a truthful and well-documented packet preserves the issues you raise, and fewer than 1% of denied in-network claims in the 2024 Marketplace dataset were appealed.

After you send it: proof, follow-up, and the mistakes that sink a packet

Answer capsule: Keep a complete copy of the packet, proof of delivery, and the decision date the plan gives you. If the plan asks for more information or denies again, follow the instructions in the new notice rather than resending the same unchanged packet. The most damaging mistakes are filing through the wrong process, missing the notice deadline, and making medical claims that aren't in the record.

Track these ten things

Date sent · how you sent it · who received it · fax confirmation, portal receipt, or tracking number · who you spoke to · confirmation number · expected decision date · any request for more information · actual decision date · your next deadline.

Call to confirm receipt in three business days

"I'm calling to confirm receipt of an appeal for [medication], submitted on [date] under case number [number]. Can you confirm the appeal and all listed attachments are in the file, tell me the expected decision date, and tell me if anything is still missing?"

If something's missing, you just saved your appeal. If they can't find it, you have your proof of delivery.

Five answers you shouldn't accept

• "We never got it." → Give them the fax confirmation or tracking number and ask them to search again by member ID and date.
• "You have to go through your doctor." → For many internal appeals you can file yourself or appoint a representative. Ask them to identify the plan provision or program rule that requires a different process.
• "There's nothing you can do." → Ask for the specific appeal rights described in your notice, in writing.
• "That policy isn't available to members." → For an ERISA-covered plan, ask again and cite the notice and relevant-document rules described above. For Medicare, Medicaid, or another plan type, use the document-access rights in that program and the instructions on your notice.
• "It's excluded, end of story." → Ask for the exact exclusion language and where it appears in the plan document.

If they ask for more information

Write the request down word for word. Confirm the new deadline. Send only what they asked for, and only what's accurate. Keep the original and your proof. Ask whether the review clock resets or pauses.

The mistakes that make a packet unusable

1. No written denial — you're appealing something that hasn't happened yet
2. The exact denial wording isn't quoted
3. No deadline recorded, or a generic deadline used instead of the one on your notice
4. Sent to the wrong destination
5. A medical fact stated with no documented source behind it
6. A patient writing in a clinician's voice
7. A benefit exclusion answered with a generic medical-necessity letter
8. An attachment named in the letter but not actually included
9. No clinician evidence at all on a clinical-criteria denial
10. An urgency claim the prescriber never made
11. No proof of submission

Number 5 and number 6 are the two that can hurt you, not just fail. Everything you write should be traceable to your records, your notice, or your clinician.

What do you do while the appeal is pending?

Answer capsule: Standard appeal timelines can run for weeks. If a plan is ending an approved course before the authorization expires, ask immediately whether concurrent-care protection keeps coverage in place. Medicaid members must meet the separate continuation conditions and short request deadline. Paying cash does not automatically withdraw an appeal, but reimbursement for a cash fill is plan-specific.

Do three things before you spend money.

Ask whether coverage continues. If the plan is stopping an approved ongoing course before the authorized period or treatment count ends, cite the concurrent-care section above. If it is a renewal after the authorization expired, ask whether the plan offers temporary continuation, but do not assume federal concurrent-care protection applies. Medicaid members should request continuation immediately if they meet the conditions in 42 CFR 438.420.

Ask for the expected decision date in writing. A standard pre-service internal appeal can take up to 30 days, and standard federal external review can take up to 45 days after the internal process. Urgent cases use different timelines.

If you pay cash, keep every receipt. Paying out of pocket does not automatically cancel the appeal. Ask the plan in writing whether a successful reversal can reimburse a fill purchased during the review; the answer depends on the plan and claim posture.

Manufacturer-direct channels are worth checking without a middleman: NovoCare for eligible Novo Nordisk products and LillyDirect for eligible Lilly products. We're not affiliated with either. Current product, eligibility, prescription, and price rules can change, so check the manufacturer page before relying on them.

### If you also need a clinician and insurance-paperwork support Ro currently offers FDA-approved weight-management options and an insurance-support workflow for eligible commercial coverage. Ro Body is $39 for the first month, then $149 per month, or as low as $74 per month when an annual plan is paid upfront. Medication is billed separately. → Check current Ro coverage support and program pricing Where Ro falls short, and who should skip it. The membership fee does not include medication, and insurance support cannot make an excluded benefit appear in your contract. Ro says people with Medicare, Medicare supplement, or TRICARE may be eligible for certain cash-pay options; that is not the same as Ro coordinating those government benefits. If your own clinician already has the records and will file promptly, using that office is usually the cheaper route. See Source 24 below.

Why we're not sending you straight to compounded semaglutide

You'll find appeal pages that are really ads for compounded GLP-1s. They tell you to skip the insurance maze entirely.

We're not doing that, and here's why. Compounded medications are not FDA-approved finished products and are not the same as the FDA-approved brand your plan denied. Commercial coverage depends on the plan's terms. Medicare Part D compound rules can cover qualifying Part D drug components in some compounds; that does not turn the compounded preparation into an FDA-approved brand or make it eligible for the Medicare GLP-1 Bridge.

If you're close to a decision on coverage for an FDA-approved medication, switching to an unrelated cash-pay path can pull you away from the goal that brought you here. Finish the appeal decision first.

If you later decide that a cash-pay compounded option is right for your budget and your clinician agrees, make that as a separate decision with clear sourcing and no implication that compounded and FDA-approved products are equivalent. That's what Find My GLP-1 Path is for.

Who made this, how, and why?

Answer capsule: This page was produced by The RX Index using current federal regulations, CMS guidance, FDA labeling, and published payer criteria reviewed at the source. It provides administrative drafting help, not medical or legal advice. Your written notice and plan documents control the process that applies to you.

Who created it. The organizational author is The RX Index. No individual medical reviewer or legal reviewer is claimed on this page.

How we built it. We reviewed the current text of 29 CFR 2560.503-1 and 45 CFR 147.136; current CMS Part D, Medicaid, and Medicare GLP-1 Bridge materials; current FDA labeling for the named drug-indication claims; Virginia's step-therapy statute; KFF's latest Marketplace appeals analysis; and the published payer criteria named on this page. We then mapped denial wording to ten procedural lanes and separated patient-generated language from clinician-supplied evidence.

Why this page exists. Most appeal templates start with a blank letter. This one starts one step earlier — with the reason your plan actually gave — because the right letter, evidence, deadline, and next move all depend on that reason.

What this page is not. Not medical advice. Not legal advice. Not a promise of coverage. Not a substitute for your denial notice, Summary Plan Description, Evidence of Coverage, or clinician record.

Our rules for the builder. It will not ask you to upload a denial notice or medical record. It will not invent a diagnosis, BMI, lab result, treatment date, dose, side effect, failed therapy, or contraindication. It will not suggest changing a diagnosis code to obtain coverage. It will not write in a clinician's voice or generate a signature or credential. It will not claim you meet criteria. It will not replace the deadline on your notice with a generic date.

Before it generates anything, you'll confirm this:

I will include only information that is documented in my records, stated in my denial notice, or confirmed by my clinician.

Frequently asked questions about GLP-1 insurance appeal letters

Can I appeal a GLP-1 denial myself, or does my doctor have to do it? You can often request the internal appeal yourself or through an authorized representative. A clinical denial still needs medical facts from the record or a clinician. Your letter organizes the case; the clinician's documentation supplies the medicine.

Is an appeal letter the same as a letter of medical necessity? No. A clinician's medical-necessity letter contains clinical reasoning and is signed by the clinician. A patient appeal letter identifies the decision, quotes the denial, requests reconsideration, and points to the supporting evidence. Many clinical denials need both.

How long does a GLP-1 appeal take? For a pre-service commercial claim under the federal standard, an internal appeal can take up to 30 days; a two-level plan can use 15 days per level. Medicare Part D benefits appeals take 7 days standard, and Medicaid managed-care appeals generally take up to 30 days. Urgent or expedited lanes generally use 72 hours, while Part D coverage determinations use 24 hours when expedited.

Does appealing cost anything? A plan subject to the federal ERISA claims rule cannot charge a fee as a condition of the internal appeal. Federal external review is free; an applicable state process may charge no more than $25 per request, must waive the fee for financial hardship, refund it if the consumer wins, and cap fees at $75 per plan year.

What if I already missed the deadline? Call the plan today, explain the situation honestly, and ask whether a late-filing, good-cause, reconsideration, or other review option applies. Do not assume the deadline is irrelevant, and do not assume every option is gone. Ask for the answer in writing.

Can my employer overrule the insurance company? A self-funded employer is the plan sponsor and may have plan-level authority or an exception process, but the administrator and plan document control who can decide. Ask the benefits administrator whether a plan-level exception exists; do not assume HR can simply order payment.

Can I appeal if my BMI dropped because the medication worked? Yes. A renewal denial can be appealed. Published criteria often use a dated baseline and a percentage response rather than today's BMI alone, but the definition of baseline varies. Attach the plan's exact renewal rule and dated records showing the correct baseline and follow-up.

Will appealing hurt my chances later? A truthful appeal is the review process the plan provides; it is not a formal "strike." What can hurt the packet is unsupported or inconsistent information. Keep every factual statement tied to the notice, record, or clinician.

Does buying the medication with cash cancel my appeal? Not automatically. Keep receipts and ask the plan whether a successful reversal can reimburse a fill purchased during the appeal. That reimbursement question is plan-specific.

Can I appeal a Medicare GLP-1 Bridge denial? No. CMS states there is no appeals process under the Bridge. A prescriber may correct and resubmit the prior authorization if information was wrong, updated, or incomplete. Separate Part D coverage determinations retain the ordinary Part D appeals process.

Do I need a lawyer? Most internal appeals and external-review requests can be filed without a lawyer. Consider legal help when an ERISA plan has issued a final denial, litigation deadlines are approaching, the financial exposure is large, or the case involves disputed plan language that you cannot resolve through the ordinary process.

Does the builder store my health information? The builder does not request your name, member ID, diagnosis, chart text, or a denial-document upload. It generates labeled placeholders from non-identifying choices. Do not paste protected health information into any free-text field. See the site privacy notice for the analytics and retention practices that apply to the live page.
