Can Express Scripts approve Mounjaro for weight loss?

Not under the diabetes policy if you don't have type 2 diabetes. If weight loss is the goal, ask about Zepbound or Wegovy instead.

What happens if Express Scripts denies Mounjaro?

Read the denial letter first -- it explains the reason and your appeal rights. Match the fix to the reason: missing information, step therapy, quantity limit, formulary, or a plan exclusion.

Can I use the Lilly Mounjaro Savings Card if I'm denied?

Possibly, if you qualify. Lilly's card is for eligible commercial patients with a type 2 diabetes prescription and excludes Medicare, Medicaid, TRICARE, VA, and DoD.

Is the TRICARE Mounjaro PA form the same as commercial Express Scripts?

No. The public form you find online is specifically for the Department of Defense TRICARE program, not a universal commercial form.

Does the Medicare GLP-1 Bridge help with Mounjaro?

No. The Medicare GLP-1 Bridge covers certain weight-management drugs -- Foundayo, Wegovy, and the Zepbound KwikPen -- starting July 1, 2026, and does not include Mounjaro. Medicare Part D can still cover Mounjaro for type 2 diabetes, subject to plan rules.

Express Scripts Mounjaro Prior Authorization: 2026 Criteria, What to Submit, and How to Fix a Denial

Why almost every holdup is a documentation gap, not a real “no” — and the exact packet that fixes it.

Disclosure: The RX Index is a pricing intelligence and comparison resource for GLP-1 telehealth providers. We may earn a commission if you use some provider links on this page. It never changes our verified facts or who we recommend. This guide is information, not medical advice.

Bottom line: An Express Scripts Mounjaro prior authorization almost always comes down to one question: is your prescription clearly for type 2 diabetes, with complete information sent by your doctor? Express Scripts says nearly all coverage reviews finish within two days of getting complete information — and electronic requests can clear in minutes. The holdup is almost always a documentation gap, not the plan’s clock.

Quick decision table — find your situation

Your situation	What it probably means	Your best next step
App or pharmacy says "prior authorization required"	More info is needed -- this is NOT a denial yet	Ask your doctor to submit the PA. Only they can.
You have type 2 diabetes (age 10+)	The clearest, strongest approval lane	Have your doctor send your diagnosis, labs, and medication history
You want Mounjaro for weight loss, no diabetes	The wrong coverage lane for Mounjaro	Ask your doctor about Zepbound or Wegovy instead
Your A1C is normal now because the meds worked	A renewal paperwork issue -- not a coverage problem	Ask your doctor to note your original diagnosis + 'continuation of care'
Express Scripts denied it	You need the written reason first	Match the fix to the denial (decoder below)
You have TRICARE	Different rules and a different form	Your provider submits the TRICARE PA (asks about diabetes + metformin)

Does Express Scripts cover Mounjaro in 2026?

Mounjaro appears on the 2026 Express Scripts National Preferred Formulary, but a spot on that list is not a promise of coverage. Express Scripts states the list is not all-inclusive, is subject to change, and does not guarantee coverage for every plan. Your real coverage depends on your specific plan documents, prior authorization rules, quantity limits, and any employer exclusions.

“Is it on the list?” and “will my plan pay for it?” are two different questions. Most Express Scripts plans can cover Mounjaro — but for type 2 diabetes, and usually only after a review.

Does Express Scripts require prior authorization for Mounjaro?

Express Scripts often requires prior authorization for Mounjaro — even when it’s on the formulary. Prior authorization (PA) is a coverage check, not a punishment. In Express Scripts’ own words, a coverage review simply means more information is needed to see if your plan covers a medication, and only your doctor can provide that information.

Read that twice: the holdup is usually missing information — not a rejection.

What “coverage review” actually means

Express Scripts uses two words for the same thing: prior authorization and coverage review. Either way, the outcome can be approved, denied, or withdrawn — and the review can’t even start until your doctor sends what’s needed.

Why your pharmacy can’t fix it

When a PA is required, your pharmacy gets an alert that more info is needed from your doctor — and only your doctor can provide it. Calling the pharmacist repeatedly won’t work. Your doctor’s office is the only lever that moves this. That one fact saves people days of wasted phone calls.

What to check in your Express Scripts account first

What to check	Why it matters
Is Mounjaro listed for your plan?	Confirms whether it can be covered at all
Does it say PA required?	Tells you a review is needed before the plan pays
Is there a quantity limit?	Caps how much the plan will cover per fill
Is the PA pending, denied, withdrawn, or expired?	Tells you exactly which section below applies to you
Is the fill set for retail, home delivery, or specialty?	Routing affects which PA process applies
What's the copay estimate after approval?	Baseline before you apply the Lilly savings card

What we actually verified for this guide

Every fact below was checked against a primary source on June 10, 2026.

What we checked	What the source says	What it means for you
Formulary status	Mounjaro is on the 2026 Express Scripts National Preferred Formulary, but the list is "not all-inclusive" and doesn't guarantee coverage	Listed does not equal approved. Your plan rules still decide.
What a PA means	Express Scripts: a coverage review "simply means more information is needed," and only your doctor can provide it	A PA alert isn't a denial
Timing	Nearly all reviews finish within two days of receiving complete info; electronic requests can clear in minutes	The holdup is usually your doctor's packet, not Express Scripts' clock
The criteria	The public Cigna/Evernorth diabetes GLP-1 policy lists Mounjaro and recommends approval for type 2 diabetes for one year when the patient is age 10+	Documented diabetes is the clean path
The auto-approval rule	A Mounjaro claim can adjudicate automatically with a recent oral diabetes medication on record -- not counting Rybelsus or metformin by itself -- and age 10+. Otherwise full PA criteria apply	Your medication history can decide whether you sail through or get reviewed
Weight loss	These GLP-1 drugs are not FDA-approved for weight loss in people without type 2 diabetes	For weight loss without diabetes, ask about Zepbound or Wegovy
Cost lever	Lilly: eligible commercial patients may pay as little as $25 for a 1-3 month fill (covered) or as low as $499 for a 1-month fill (commercial without coverage); government plans excluded; card runs through Dec 31, 2026	Your copay depends on your plan; the $25 card is the main commercial lever
Appeals timing	Express Scripts: urgent appeals within 72 hours, standard pre-service ~15 days, post-service ~30 days	A denial has a clock and a clear path

What this page is not: not medical advice, not a promise of approval, not a substitute for your denial letter, and not a guide to coding a diagnosis you don’t have.

What are the Express Scripts Mounjaro prior authorization criteria in 2026?

Quick answer: The public Cigna/Evernorth diabetes GLP-1 policy lists Mounjaro under type 2 diabetes criteria and generally recommends approval for one year when the patient has type 2 diabetes and is age 10 or older. It does not recommend approval for weight loss in people who don’t have type 2 diabetes. Your specific plan can add steps.

A quick definition: Mounjaro is the brand name for tirzepatide, a once-weekly injection. The FDA approved Mounjaro to help adults — and kids 10 and older — manage blood sugar in type 2 diabetes, used with diet and exercise. That FDA approval is the hinge everything swings on.

The clean path: documented type 2 diabetes

If you have a documented diabetes diagnosis, you’re on the strongest path. Your doctor sends the diagnosis (the code insurers look for is in the E11 family of ICD-10 codes — the standard list of diagnosis codes), your lab work, and your medication history. That’s the core packet for the diabetes path.

The hidden rule: why some claims sail through and others get stuck

Under the GLP-1 policy we verified, a Mounjaro claim can go through automatically — with no manual review — if your pharmacy record shows you recently filled one oral (pill) diabetes medicine — not counting Rybelsus or metformin by itself — and you’re at least 10 years old. If that history isn’t there, the full review kicks in instead.

If you just switched diabetes meds, or you’re brand new to treatment, expect a full review. That’s normal.
If your refills suddenly need a fresh PA, a change in your recent medication history may be why.
The cleanest, fastest setup is a documented diabetes diagnosis plus a clear medication history your doctor can point to.

Safety note: Getting coverage approved is not the same as being medically cleared. Mounjaro carries a boxed warning about a risk of thyroid tumors seen in animal studies, and it’s not for people with a personal or family history of medullary thyroid cancer or a condition called MEN 2. Your clinician decides whether it’s right for you.

What this means if you don’t have diabetes

If you’re seeking Mounjaro purely for weight loss without type 2 diabetes, the diabetes policy won’t approve it — and more paperwork won’t change that. The right move is asking your doctor about Zepbound. Mounjaro and Zepbound both contain tirzepatide — the same active drug — but they’re different brands with different FDA approvals, and insurance follows those labels exactly. See Express Scripts Zepbound coverage →

What should your doctor submit for an Express Scripts Mounjaro PA?

Your doctor should send a complete clinical packet — not just “patient wants Mounjaro.” Express Scripts says most reviews are quick once they have complete information, so a thorough first submission is the single biggest time-saver.

A stalled PA usually isn’t about whether you qualify. It’s about whether your doctor sent everything. A busy office can fire off a bare-bones request, get a “need more info,” and the clock resets. You can prevent that.

The prescriber packet checklist (and which denial each item prevents)

What to include	Which denial it prevents	How to ask for it
Type 2 diabetes diagnosis (ICD-10 E11.x)	"Missing diagnosis / weight-loss only"	"Can you make sure my documented type 2 diabetes diagnosis is on the PA?"
Original + recent A1C / labs (A1C is a 3-month blood-sugar average)	"Not enough clinical info"	"Can you include my original diagnostic labs and my latest labs?"
Medication history	"Step therapy"	"Can you list my prior diabetes meds, dates, and any side effects?"
Exact dose + quantity	"Quantity limit"	"Can the PA match my exact dose, quantity, and days' supply?"
Renewal / continuation note	"Approval expired"	"If this is a renewal, can you mark it 'continuation of care'?"
Why alternatives don't fit	"Try a preferred drug first"	"Can you document any intolerance or reason other options aren't right?"
A real chart note	"Not medically necessary"	"Can you attach the visit note, not just a one-line answer?"
The denial letter (if appealing)	A failed appeal	"Can we appeal the exact reason on the letter?"

Copy this message to your doctor

“My Express Scripts pharmacy benefit needs a coverage review (prior authorization) for Mounjaro. Can your team submit it electronically and include my documented type 2 diabetes diagnosis, my original and current A1C/labs, my prior diabetes medication history, my exact dose and quantity, and a continuation-of-care note if this is a renewal? If anything’s missing, please let me know what you need from me.”

That message does more than a dozen phone calls. It tells the office exactly what to send the first time.

Free — first PA, renewal, denial, or appeal

What if Express Scripts denies your Mounjaro PA?

First, get the denial reason in writing — don’t guess. Express Scripts says your appeal rights and steps are explained in the denial letter, and the right fix depends entirely on why you were denied. Some denials are fixable. A true plan exclusion usually isn’t — and knowing the difference saves you weeks.

Many alerts that feel like a denial are really just “we need more info.” An actual denial is different — and if you got a denial letter, read it before you do anything else.

Denial decoder — and what to say to Express Scripts, word for word

Denial reason	What it means	What to ask Express Scripts
Missing type 2 diabetes diagnosis	The PA didn't clearly document diabetes	"Can my doctor resubmit with my documented type 2 diabetes diagnosis and labs?"
Weight loss / obesity only	Mounjaro is in the wrong lane for this goal	"Is Zepbound or Wegovy covered on my plan for weight management?"
Step therapy	The plan wants proof you tried other meds first	"Which medications must be tried first, and can my doctor request a step-therapy exception?"
Quantity limit	Your dose or days' supply doesn't match plan rules	"What quantity limit applies, so my doctor can correct the prescription?"
Not preferred / formulary	Mounjaro may not be preferred on your plan	"What's the preferred alternative, and can we request a formulary exception?"
Approval expired	Your prior PA ran out or your plan changed	"What do you need for a renewal, and can it be continuation of care?"
Plan exclusion	Your plan doesn't cover this use/category	"Is this a benefit exclusion, and is there any exception process?"

The honest truth about denials

A prior authorization can’t force Express Scripts to cover Mounjaro for something your plan doesn’t cover. If your denial is a true plan exclusion, or a weight-loss-only request without diabetes, more paperwork just wastes time. The smarter move is to find the lane that is covered: Mounjaro for documented diabetes, Zepbound or Wegovy for weight management, or a cash-pay route if insurance won’t budge.

How long do you have, and how fast are appeals?

Appeal type	Timeline
Urgent appeal	No later than 72 hours from receiving the request
Standard pre-service appeal	Within about 15 days
Standard post-service appeal	Within about 30 days

Appeal script — what to say, word for word

“Can you tell me the exact denial reason — is it missing information, step therapy, a quantity limit, formulary status, or a plan exclusion? I’d like the denial letter and the appeal deadline and instructions. If it’s missing documentation, my doctor can submit what you requested — and we’d like an urgent review if my situation qualifies.”

How long does Express Scripts Mounjaro prior authorization take?

Express Scripts says nearly all coverage reviews finish within two days of receiving complete information from your doctor — and electronic requests can clear in minutes. The delay you feel is usually before that clock starts: your doctor’s office hasn’t sent everything yet. Get the full packet in the first time, and the wait shrinks.

The fastest route is electronic. Express Scripts notes that only your doctor can submit the form, suggests using Surescripts, and says sending it electronically can get a response within minutes.

Status decoder — what each status means and what to do

Status	What it means	What to do
Pharmacy says PA required	Not approved yet	Contact your doctor's PA team
Doctor says 'submitted'	May still be pending, or info may be incomplete	Check the portal; ask the date and method it was sent
PA pending	Review may be underway	Ask if Express Scripts has complete info
More information needed	The packet is incomplete	Ask your doctor what was requested
Denied	Not approved as submitted	Get the letter; match the fix to the denial reason above
Approved before, now PA required again	Prior approval expired or plan changed	Submit a renewal/continuation packet

What if your A1C is normal now because Mounjaro worked?

This is a renewal paperwork problem — not a “you’re not diabetic anymore” problem. Ask your doctor to include your original type 2 diabetes diagnosis, your original lab history, your treatment timeline, and a continuation-of-care note. The whole point of treatment is to control your numbers; the PA just needs to show the full story, not a single snapshot.

Express Scripts explains that you may need a new coverage review because your approval expired or your plan changed — and if it’s approved before the expiration date, coverage continues without interruption. Renew before you run out, with the original diagnosis on the record.

What to ask your doctor

“My A1C is well-controlled now because Mounjaro is working. For the renewal, can you make sure the PA shows my original type 2 diabetes diagnosis, my original A1C/labs, my treatment history, and that this is continuation of care? I don’t want a good lab result to make it look like I was never diabetic.”

What not to do: don’t exaggerate, backfill, or ask anyone to miscode your chart. Use only what’s true and documented by your clinician. A controlled A1C on treatment is exactly what success looks like — and a good doctor’s note frames it that way.

What if Express Scripts wants step therapy before Mounjaro?

Step therapy means your plan wants proof you tried certain other medicines first — or that they’re not right for you — before it covers Mounjaro. The fix is documentation: prior diabetes meds with dates and outcomes, side effects, and a step-therapy exception request if appropriate.

Step therapy shows up here because the diabetes policy uses recent oral diabetes medication history in its automatic checks, and the Express Scripts TRICARE form for Mounjaro asks about therapies like metformin, Bydureon BCise, and Trulicity. Your commercial plan may handle it differently — but the documentation that wins is the same.

Medication history checklist

Metformin use -- dates, response, side effects
Other oral diabetes medicines tried
Any prior GLP-1 medicines
Allergies, intolerances, or reasons a med wasn't a fit
Kidney function notes, if relevant
Your current medication list
Why your doctor is choosing Mounjaro now

Step therapy exception script

“Can you check whether this is a step-therapy denial, and whether my doctor can submit a step-therapy exception based on my documented history — what I’ve tried, what failed, and what I couldn’t tolerate?”

Where do you find the Express Scripts Mounjaro prior authorization form?

For most commercial Express Scripts members, the best route isn’t a form you download — it’s your doctor submitting electronically. Electronic prior authorization (ePA) is the fastest path, and only your prescriber can submit it. Express Scripts points doctors to electronic options at express-scripts.com/PA, with phone and fax as backups.

Ask your doctor’s office:

“Can your team submit this through electronic prior authorization for Express Scripts — like the system built into our EHR, or Surescripts/CoverMyMeds? Electronic requests are faster.”

TRICARE warning — don’t grab the wrong form: There’s a public Express Scripts Mounjaro PA form floating around online, but it’s specifically the Department of Defense TRICARE pharmacy form. If you’re a commercial member, that’s not your form. Use it only if you actually have TRICARE.

Express Scripts and Evernorth also list state-specific request forms for cases where ePA or phone can’t be used. When in doubt, the number on your prescription ID card will point you to the right one.

Can Express Scripts cover Mounjaro for weight loss?

Under the diabetes GLP-1 policy, Mounjaro is reviewed as a diabetes medicine — not a weight-loss medicine. It generally won’t be approved for weight loss in someone without type 2 diabetes. Mounjaro and Zepbound contain the same medicine (tirzepatide) — but to an insurer, the brand name, the FDA-approved use, your diagnosis, and your benefit category all matter. Mounjaro lives in the diabetes column.

A reality check on weight-loss coverage in general: the KFF 2025 employer survey found that GLP-1 weight-loss coverage reached 16% of firms with 200–999 workers, 30% of firms with 1,000–4,999 workers, and 43% of firms with 5,000 or more workers. So plenty of plans still don’t cover it. If yours does, there may be a cost cap: Evernorth/Express Scripts launched an option that limits the monthly copay for GLP-1 weight-loss medicines to no more than $200 — but that’s something your employer chooses to add, not something you can switch on yourself.

Ro’s free GLP-1 Insurance Coverage Checker contacts your insurer and tells you whether Zepbound or Wegovy is covered on your plan and whether a PA is required — useful intel before spending a dime. Ro offers FDA-approved options including Wegovy, Zepbound, and Ozempic. Ro doesn’t carry Mounjaro and can’t guarantee approval; its insurance help is for commercial plans.

How much will Mounjaro cost after Express Scripts approves it?

With a covered commercial plan and an approved PA, your copay depends on your plan, tier, deductible, pharmacy, and quantity — and eligible commercial patients may pay as little as $25 a month with Eli Lilly’s Mounjaro Savings Card. Without coverage, Mounjaro runs roughly $1,000–$1,200 a month at retail. Treat these as ranges, not guarantees, and confirm your own number in your portal.

Your situation	What to expect
Commercial plan covers Mounjaro, PA approved	Copay set by your plan. Lilly says eligible commercial patients may pay as little as $25 for a 1-, 2-, or 3-month fill, subject to monthly and yearly savings limits
Commercial plan that doesn't cover Mounjaro	Lilly's card may let eligible patients pay as low as $499 for a 1-month fill, with savings up to $8,411/year -- for an approved (diabetes) use
Government insurance (Medicare, Medicaid, TRICARE, VA)	The Mounjaro Savings Card cannot be used with any government plan
No insurance at all	The card needs commercial insurance; uninsured patients can look into Lilly Cares (income-based)
Denied, no covered alternative	Retail is high -- about $1,000-$1,200/month. Check LillyDirect for any current self-pay pricing before you count on it
Weight-loss goal	Compare Zepbound or Wegovy coverage, or their cash-pay options, instead

Lilly’s card requires commercial insurance, a valid Mounjaro prescription for type 2 diabetes, U.S. residency, and age 18+. Program runs through December 31, 2026. See the full Mounjaro Savings Card guide →

Should you use Ro or Sesame to get unstuck?

Use your own doctor first if they know your diabetes history and will submit the PA — that’s the fastest, cheapest path. A telehealth provider helps in three specific cases: you don’t have a prescriber, you were denied and want a free read on your coverage, or your plan won’t cover it and you’re weighing a different route.

The honest part most pages skip: If you have type 2 diabetes and a commercial Express Scripts plan, you probably don’t need to pay for a telehealth membership at all. Your own doctor plus your own pharmacy is the cheapest route. And: Ro doesn’t carry Mounjaro, and no telehealth service can force your plan to approve it.

Provider	What they offer (verified June 10, 2026)	The honest caveat
Ro	Free GLP-1 Insurance Coverage Checker that contacts your insurer and reports coverage + whether a PA is required; FDA-approved options including Wegovy, Zepbound, and Ozempic; membership $39 first month, then as low as $74/month with annual prepay (or $149/month), medication billed separately	Ro doesn’t carry Mounjaro and can’t force approval; its insurance help centers on the medications it supports for commercial plans
Sesame	Pick your own provider; providers can help with PA paperwork; broad menu including Mounjaro itself; program $59/month with annual plan or $99 month-to-month, medication billed separately; Costco members get extra discounts	Cash Mounjaro is roughly $1,080–$1,300/month (no self-pay discount); medication billed separately

When Ro fits

Ro’s free GLP-1 Insurance Coverage Checker is useful when you want a free coverage report and you may be open to Wegovy, Zepbound, or Ozempic if Mounjaro isn’t available through your plan. Telehealth insurance concierges generally work with commercial insurance — if you have Medicare, Medicaid, or TRICARE, confirm the provider’s rules first.

When Sesame fits better

Prefer to choose your own doctor and talk it through? Sesame Care lets you browse providers, read reviews, and pick one. Sesame says its providers can assist with prior authorization paperwork, and its menu is broad — it can prescribe Mounjaro itself, plus Zepbound, Wegovy, Ozempic, and more. Heads up on cash price: if you’re paying out of pocket for branded Mounjaro, expect roughly $1,080–$1,300 per month — Mounjaro has no manufacturer self-pay discount the way Zepbound does. Sesame shines for the visit and PA help, not for cheap cash Mounjaro.

Who should NOT click a provider link yet:

You already have a responsive doctor submitting your PA

You have TRICARE or other government insurance (work it through your plan)
Your problem is a true employer exclusion
You're trying to force Mounjaro for weight loss without diabetes (switch to Zepbound instead)

The scripts: exactly what to say

The fastest way to get unstuck is to ask narrow, answerable questions of the right person.

Call Express Scripts:

"I'm checking coverage for Mounjaro on my plan. Can you tell me whether Mounjaro is covered, whether prior authorization is required, whether step therapy or quantity limits apply, whether this is a new PA or a renewal, and the current status -- pending, denied, withdrawn, or waiting on my doctor?"

Message your doctor's office:

"Express Scripts needs a coverage review for Mounjaro. Can your team confirm it's been submitted electronically and that it includes my documented type 2 diabetes diagnosis, my relevant labs/A1C, my prior medication history, my dose and quantity, and continuation-of-care context if this is a renewal?"

Appeal a denial:

"Can we review the denial letter and appeal the exact reason? If it was missing diagnosis, missing labs, step therapy, or a quantity limit, can we submit the documentation Express Scripts requested -- and can we request an urgent review if my situation qualifies?"

Ask HR or benefits (only if a true exclusion may apply):

"Can you confirm whether my plan excludes Mounjaro, diabetes GLP-1 medicines, or weight-loss medicines -- and whether there's any exception process?"

Express Scripts Mounjaro prior authorization: FAQ

Quick, direct answers to the questions people ask right after the main one — coverage, criteria, forms, denials, timing, savings, renewals, weight loss, TRICARE, Medicare, and provider help.

Does Express Scripts cover Mounjaro?: Often yes, but only under your plan's rules. Mounjaro appears on the 2026 Express Scripts National Preferred Formulary, yet that list doesn't guarantee coverage for every plan. Check your portal.
Does Express Scripts require prior authorization for Mounjaro?: Many members see a prior authorization (coverage review) requirement. Express Scripts says it simply means more information is needed from your doctor to confirm coverage.
What are the Express Scripts Mounjaro prior authorization criteria in 2026?: The public Cigna/Evernorth diabetes GLP-1 policy routes Mounjaro through type 2 diabetes criteria and generally recommends approval for one year when the patient has diabetes and is age 10 or older. Your plan can add steps.
Can Express Scripts approve Mounjaro for weight loss?: Not under the diabetes policy if you don't have type 2 diabetes. If weight loss is the goal, ask about Zepbound or Wegovy instead.
How long does an Express Scripts Mounjaro PA take?: Express Scripts says nearly all reviews finish within two days of receiving complete information from your doctor, and electronic requests can clear in minutes. Incomplete information is the usual delay.
What happens if Express Scripts denies Mounjaro?: Read the denial letter first -- it explains the reason and your appeal rights. Match the fix to the reason: missing information, step therapy, quantity limit, formulary, or a plan exclusion.
Can I use the Lilly Mounjaro Savings Card if I'm denied?: Possibly, if you qualify. Lilly's card is for eligible commercial patients with a type 2 diabetes prescription and excludes Medicare, Medicaid, TRICARE, VA, and DoD.
Is the TRICARE Mounjaro PA form the same as commercial Express Scripts?: No. The public form you find online is specifically for the Department of Defense TRICARE program, not a universal commercial form.
Does the Medicare GLP-1 Bridge help with Mounjaro?: No. The Medicare GLP-1 Bridge covers certain weight-management drugs -- Foundayo, Wegovy, and the Zepbound KwikPen -- starting July 1, 2026, and does not include Mounjaro. Medicare Part D can still cover Mounjaro for type 2 diabetes, subject to plan rules.
