What GLP-1 Does Express Scripts Cover? 2026 Drug List by Plan

What GLP-1 does Express Scripts cover? On the current 2026 Express Scripts national documents — revised July 1, 2026 — the Weight Loss row names six preferred alternatives: Wegovy Pens, Wegovy HD, Wegovy Tablets, the Zepbound single-dose Pen, Foundayo, and generic liraglutide. The main drug list also names six additional diabetes-focused entries: Ozempic, Ozempic Tablets, Rybelsus, Mounjaro, Trulicity, and Soliqua. Generic liraglutide also has diabetes uses, so these are search buckets, not a count of FDA indications.

Two Zepbound devices are excluded from the current national list: the KwikPen and the vials. The KwikPen was added to the excluded list on July 1, 2026. The single-dose Zepbound Pen stayed a preferred alternative.

Now the part almost nobody tells you. That list is a starting point, not your answer. Your employer, union, health plan, or other plan sponsor decides which benefit you get — and we found two Express Scripts documents with the same base title that give completely different answers. The national version names six weight-loss entries. The Teacher Retirement System of Texas version names none.

We'll show you both. Then we'll show you how to find out which one is yours in about five minutes.

Best for you if

• Your pharmacy card says Express Scripts and you're on an employer or union plan
• You were just prescribed a GLP-1 and want to know the cost before your appointment
• Your refill suddenly stopped working this summer
• You're comparing Wegovy, Zepbound, Foundayo, Ozempic or Mounjaro coverage

Not for you if

• You're on Medicare. Jump to the Medicare section — the rules are completely different, and there is a separate $50 program for people who qualify.
• You're on TRICARE. Express Scripts runs that too, but off a separate military rulebook. See our TRICARE GLP-1 page.
• You're on Medicaid. Your state Medicaid program and managed-care plan set the benefit. This national commercial list is not your rulebook.
• You want to know which GLP-1 works best. That's a medical question for your doctor. This page is about who pays.

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.

What GLP-1 Does Express Scripts Cover? 2026 Drug List

The current documents show six preferred alternatives in the Weight Loss row and six additional diabetes-focused entries on the national drug list. All three current Wegovy entries are on it. Zepbound is on it in exactly one form — the single-dose Pen. Two other Zepbound devices are named as excluded.

First, two words you'll see over and over. A formulary is just the list of drugs your plan may help pay for. Express Scripts calls this one the National Preferred Formulary, or NPF. It is an abbreviated national list that plan sponsors can use or change.

We downloaded the current exclusion document and read the current national list on August 11, 2026. Here's what's in them.

Sources: 2026 Express Scripts National Preferred Formulary, document PRMT22157-26 (07/01/2026), and 2026 National Preferred Formulary Exclusions, document EXCL-NPF-26 (07/01/2026). Both checked August 11, 2026. FDA status for Wegovy HD and Foundayo was checked against FDA.

This table reports what the documents say. It is not a medical recommendation, and it does not prove your own plan covers any product.

Two things this document actually proves

1. None of these GLP-1 entries is marked [SP] in the abbreviated national list.

Express Scripts uses a little tag — [SP] — next to specialty medications. It appears throughout the document. It is not printed next to Wegovy, Zepbound Pen, Ozempic, Foundayo, or the other GLP-1 entries above.

That proves one narrow thing: the abbreviated national list itself does not mark these entries as specialty drugs. It does not prove what tier your own plan uses, whether your plan requires a specialty pharmacy, or what your cost share will be.

2. The document has no tiers, no copays, and no prior-authorization codes at all.

We went looking. The key explains only three tags: injectable, over-the-counter, and specialty. There is no tier column. No "PA" flag. No quantity-limit column.

So here's what that means for you, said plainly: this document can tell you a drug appears on the national list. It cannot tell you what you'll pay or whether you'll need approval first. A page quoting one universal Express Scripts tier or copay for Wegovy is either using a different plan document or claiming more than this national list can prove.

We'd rather tell you the blank is blank than fill it in.

One rule that will save you a headache

If a drug isn't on the abbreviated list, that does not automatically mean your plan refuses it. The document says it is not all-inclusive, does not guarantee coverage, and is not used the same way by every prescription plan.

Missing from the national list and excluded from your plan are two different things. Keep them separate and you'll ask better questions.

### Look up your own drug first. It takes about five minutes. Sign in at express-scripts.com and open Price a Medication under Prescriptions. Type the exact drug and form — "Zepbound single-dose pen," not just "Zepbound." Write down what it says and what it costs. Express Scripts says the results show whether the medication is covered and give pricing information when the tool is available through your plan. That result beats every article on the internet, including this one.

Why did my Zepbound suddenly stop being covered?

On July 1, 2026, Express Scripts added the Zepbound KwikPen to its excluded national list. The single-dose Zepbound Pen stayed a preferred alternative. If a KwikPen refill worked in June and started rejecting in July, the device change is the first thing to check.

If this is you, take a breath. You didn't do anything wrong.

Here's the exact row from the current exclusion document:

Source: EXCL-NPF-26 (07/01/2026), Weight Loss row.

Three Zepbound devices. Three different entries. The same active ingredient — tirzepatide — but different products in the claim system.

Why does the box matter? Because pharmacies and insurance plans do not process only the word "tirzepatide." They process a specific product and National Drug Code. To the computer, a KwikPen and a single-dose pen are different items — and only the single-dose Pen is preferred on this national list.

What to actually do: call the number on your card first, then call your prescriber's office and say this.

"The July 1 Express Scripts national list prefers the Zepbound single-dose Pen and excludes the KwikPen. Does my own plan follow that list? If it does, can you send the preferred single-dose Pen instead?"

If the device is the only problem, a replacement prescription may avoid a full appeal. Do not assume that is the only problem until your plan confirms it.

### Copy this appointment note Document: Express Scripts National Preferred Formulary Exclusions Document number: EXCL-NPF-26 Version date: 07/01/2026 Preferred Zepbound form: Zepbound Pens Excluded Zepbound forms: Zepbound KwikPens and vials Ask these three questions: 1. Does my plan follow this July 1 national list? 2. Should my prescription name the Zepbound single-dose Pen? 3. Does my plan also require prior authorization or set a quantity limit?

Why does every website give me a different answer?

Express Scripts uses the same document number for its 2026 exclusion list, then revises the document during the year. The PDF does not contain a built-in change log. We found four dated copies of EXCL-NPF-26, and the weight-loss row is different in each one.

This is the real reason you've read three articles and gotten three answers. It isn't that everyone is careless. It's that the document moves and almost nobody prints the date.

Here's what we found. Same document number — EXCL-NPF-26 — every time.

Sources: an August 8, 2025 plan-sponsor copy, a November 1, 2025 copy, an April 1, 2026 copy, and the current July 1, 2026 Express Scripts copy. All four rows read directly on August 11, 2026.

Look at what changed inside one plan year:

• August to November: generic liraglutide appeared as a preferred alternative.
• November to April: Saxenda disappeared from the Weight Loss row, Wegovy Tablets appeared, and "Wegovy" became "Wegovy Injection."
• April to July: the Zepbound KwikPen became excluded, while Foundayo and Wegovy HD appeared as preferred alternatives.
• July wording: "Wegovy Injection" changed to "Wegovy Pens."

The 10-second trick that protects you from stale advice

Open the PDF. Scroll to the bottom of any page. Look for the date in parentheses next to the document number.

For the copy this page uses, the footer must say EXCL-NPF-26 (07/01/2026).

If it shows an earlier date, you are reading an older version. That is the single most useful sentence on this page, and we'd tell you even if it made our own work harder. It's how we caught that our earlier version of this page was quoting an older document.

Why stale pages can be confidently wrong

A stale page may still look polished. The problem is the date, not the design.

• A page based on the April copy can miss the new Zepbound KwikPen exclusion.
• A page based on the November copy can miss Wegovy Tablets, Wegovy HD, and Foundayo.
• A page using a plan-specific formulary can correctly say a drug is absent for that plan while being wrong about the national list.
• A page that never prints the document date gives you no way to tell which answer you are reading.

That is the whole story. Check the footer before you change a prescription.

Does Express Scripts decide, or does my employer?

Express Scripts builds drug lists and processes pharmacy claims under the plan's rules. Your employer, union, health plan, or other plan sponsor decides which benefit design to use and whether weight-loss medication is included at all. That's why two people can hand over an Express Scripts card at the same pharmacy and get opposite answers.

This is the part that trips up almost everyone, so let's be very clear about who does what.

Express Scripts is a pharmacy benefit manager. It manages the drug side of a health benefit, negotiates with drugmakers and pharmacies, builds drug lists, and applies the rules selected for the plan.

Your plan sponsor picks the package. It can use the national list, customize it, or leave out a whole category. The sponsor may be your employer, union, health plan, benefit fund, government program, or another organization.

Proof: two Express Scripts formularies that disagree

We didn't want to just assert this, so we compared the national document with a plan-specific Express Scripts document posted for the Teacher Retirement System of Texas.

Both documents use the base title "2026 Express Scripts National Preferred Formulary." The second adds "For Teacher Retirement System of Texas." The national document is a full-year list revised July 1. The TRS document says it is effective July 1 through December 31, 2026.

Sources: PRMT22157-26 (07/01/2026) and 2026 Express Scripts National Preferred Formulary for Teacher Retirement System of Texas, document CRP1693104A, effective July 1–December 31, 2026. Both read August 11, 2026.

Read that again. Same company. Same base title. Same year.

The national list has six weight-loss entries. The TRS plan-specific list has none — and it omits Ozempic too.

If your pharmacy benefit uses this TRS ActiveCare document, "the national list has Wegovy" still does not answer your question. That's not a loophole or a mistake. That's how the system is built.

Some employers print their answer on their own benefits page

Here's a shortcut worth knowing. Large employers sometimes publish their own exclusions instead of making you guess from the national list.

Duke University's current pharmacy-benefit page says its plans do not cover anorexiants used for weight reduction, naming Wegovy and Zepbound among the examples. It also says several diabetes GLP-1s may not be covered when prescribed for a use other than type 2 diabetes. Duke marks its linked exclusion list as current as of July 1, 2026.

Neither of those rules comes from the generic national list. They are Duke plan rules.

Try this: search your employer's name plus "Express Scripts formulary" or "weight-loss drug coverage." Universities, school systems, government agencies, unions, and large companies sometimes post their answer publicly. If yours does, you may have your answer in 30 seconds — with your plan sponsor's own rule printed on it.

The one question to ask HR

Most people call HR and ask "do we cover Wegovy?" and get a shrug. Ask this instead:

"Does our pharmacy plan include anti-obesity medications, and did our plan adopt the Evernorth option that caps Wegovy and Zepbound at no more than $200 a month?"

Anti-obesity medications is the phrase benefits departments often use. It gets you closer to the benefit decision instead of one brand name. And the $200 cap is real — but only for plan sponsors that adopted that option. More on that below.

No honest national percentage can answer for you

Express Scripts does not publish a live public list showing which employers include weight-loss drugs. We could not verify one current national approval rate or one current coverage percentage that would settle your plan.

So we are not giving you a coin-flip estimate. Your plan document, portal result, and member-services answer matter more than a market average.

### Pick your rulebook before you do anything else | Your card or program | Start here | |---|---| | Employer, union, or commercial plan with Express Scripts | Your own Price a Medication result and the number on your card | | Medicare Part D | Your Part D formulary and the separate Medicare GLP-1 Bridge rules | | TRICARE | The TRICARE Formulary Search Tool and military prior-authorization form | | Medicaid | Your state program and managed-care plan documents | The national commercial list fully answers none of the last three rows.

How do I check my exact Express Scripts coverage?

Sign in at express-scripts.com and open Price a Medication under Prescriptions. Enter the exact medication and form, then save the coverage status and price it shows. Express Scripts says this tool shows whether a drug is covered along with pricing for your specific plan when the tool is available through that plan.

Five steps. About five minutes. This is the part that actually settles it.

Step 1 — Know which lane you're in

Step 2 — Search the exact product, not the ingredient

This is where most people get a wrong answer. Searching "Zepbound" can show you one device's status when you were prescribed another.

Search the exact name on the prescription:

• Zepbound Pen · Zepbound KwikPen · Zepbound vial
• Wegovy Pens · Wegovy Tablets · Wegovy HD
• Ozempic · Ozempic Tablets
• Rybelsus, with the strength
• Foundayo, with the strength

Step 3 — Save what it says

Screenshot it. Seriously. You'll want it later if anyone tells you something different.

Write down: covered or not covered · prior authorization needed · quantity limit · estimated price · pharmacy · supply amount (30 or 90 days).

Step 4 — Call the number on your card and ask five things

Not "is Wegovy covered." Ask these:

1. Is this exact drug and form on my current drug list?
2. Is the whole weight-loss medication category covered, or excluded?
3. Which written prior-authorization policy applies to my prescription?
4. Is there a preferred form or alternative you'd rather I use?
5. Can you send me that in writing, or give me a reference number?

Question 2 is the one that saves you weeks. If the answer is "the category is excluded," ordinary prior-authorization paperwork on one drug will not add a benefit your plan left out. You would rather know that on day one than day forty.

Step 5 — Have your prescriber check before they send it

Express Scripts says a prescriber using Real-Time Prescription Benefit may be able to see coverage, pharmacy choices, cost, and approval requirements before writing the prescription. Not every prescriber has this function in the electronic health record.

Most patients have never heard of it. Ask: "Can you check my real-time prescription benefit before you send this?" It may prevent a rejection before it happens.

Why an approved prior authorization can still show "not covered"

A prior authorization and a pharmacy benefit answer two different questions.

• Prior authorization: Do the facts your clinician submitted meet the clinical rule?
• Benefit or formulary status: Did your plan include this drug, form, use, and category?

An approval does not always override a benefit exclusion, a device change, a pharmacy restriction, or a plan change. If your portal says "not covered" while an authorization looks active, ask this:

"Is the authorization active for this exact product, and is that product still in my benefit? If not, what changed and on what date?"

Get both answers in writing.

What do "covered," "preferred," "prior authorization," and "excluded" actually mean?

These terms are not interchangeable, and mixing them up sends people down the wrong path for weeks. "Preferred" describes a position on a drug list. "Prior authorization" means the plan wants more information before it pays. "Excluded" means that drug or form sits outside the listed benefit unless an exception applies.

The distinction that matters most:

• A prior-authorization problem means the plan is asking for a review. It does not, by itself, guarantee the benefit exists.
• A benefit-exclusion problem means the plan sponsor left out the category. More paperwork on the same request usually will not change the plan design.

These need completely different responses. Figure out which one you have before you spend another week on it.

Does Express Scripts cover Wegovy or Zepbound?

On the July 2026 national list, Wegovy HD, Wegovy Pens, Wegovy Tablets, and Zepbound Pens are named preferred alternatives in the Weight Loss row. Zepbound KwikPens and Zepbound vials are excluded. A member's own plan can still customize the list or leave out weight-loss medication entirely.

Notice what's happening here. The national paperwork gives Wegovy three listed entries and Zepbound one listed entry.

That's not a medical statement. Wegovy and Zepbound are different medicines and only your clinician should choose between them. It is a paperwork statement: the current national row gives semaglutide more listed entries than tirzepatide.

If your clinician says more than one option is medically appropriate, the device and formulary difference is worth mentioning at your appointment.

For the full Zepbound approval rules — the clinical gate, the device gate, plan overrides, and denial handling — see Express Scripts Zepbound prior authorization. We keep that detail there instead of repeating a watered-down version here.

One requirement that catches people off guard

Some employer plans require a subset of people using a GLP-1 for weight loss to enroll and take part in a lifestyle program before receiving the medication through EnGuide Pharmacy. Express Scripts says this requirement is chosen by the employer or health plan.

So you can clear one approval step and still get held up because you have not joined a program you did not know about. Ask up front: "Does my plan require a lifestyle program for GLP-1 coverage or EnGuide delivery?"

Does Express Scripts cover Ozempic, Mounjaro, or other diabetes GLP-1s?

Ozempic, Ozempic Tablets, Rybelsus, Mounjaro, Trulicity, and Soliqua are all printed on the July 2026 Express Scripts national drug list. Being on that list does not prove any individual plan covers the drug, and the list itself does not show prior-authorization rules.

We read the drug list ourselves and those six names are on it.

But here's a nuance worth understanding, because it's where a lot of confusion comes from. Plans use two different kinds of documents:

• A drug list says which products are listed for the benefit.
• A prior-authorization policy says what a clinician may have to prove before the plan pays.

A drug can appear in a clinical policy and still be absent from your plan's list. Or it can be listed and still need approval. Two documents. Two different questions. Neither one is your final answer.

The naming detail that will trip you up

Rybelsus and Ozempic Tablets both exist in 2026. They are not simple old-and-new names for the same tablet strength. The FDA label says they are not substitutable milligram for milligram and gives specific switching instructions.

Source: FDA prescribing information for Rybelsus and Ozempic Tablets, revised January 2026 and checked August 11, 2026.

So "oral semaglutide" is not one search item. Read the exact brand name and strength from the prescription, then search that exact product.

That one is worth 20 minutes of your life.

Please don't try the diabetes workaround

You'll see this suggested online: get prescribed Ozempic or Mounjaro instead of Wegovy or Zepbound because the diabetes products may have a different benefit path.

Those products have different FDA-approved uses and different plan rules. A diabetes benefit is not a back door that turns a diagnosis you do not have into a covered claim.

More importantly: we don't help people misrepresent a diagnosis to get coverage. Your prescriber puts their license behind what they write, and a diagnosis that isn't yours can follow you through your medical record for years. If you have type 2 diabetes, that's a real and legitimate treatment path. If you don't, it isn't one.

Does Express Scripts require prior authorization for a GLP-1?

An Express Scripts plan may require prior authorization for one or more GLP-1s, but there is no single universal checklist. The criteria come from the policy your specific plan uses. The abbreviated member drug list carries no prior-authorization codes at all, so it cannot tell you whether approval is needed.

Two things and then we'll point you somewhere better.

One: prior authorization can't create a benefit your plan doesn't have. Settle the category question first. Then work on the paperwork.

Two: the current exclusion document sends prescribers to esrx.com/PA to request a coverage review. Express Scripts also encourages electronic prior authorization and Real-Time Prescription Benefit when the prescriber's system supports them.

For the actual Zepbound criteria — BMI thresholds, plan overrides, approval periods, renewal rules, and denial handling — see Express Scripts Zepbound prior authorization. We're not going to publish a watered-down version here.

What should I do if Express Scripts says my GLP-1 is not covered?

Find out which of five things happened before you change anything: the wrong form, missing prior authorization, that specific drug excluded, the whole weight-loss category excluded, or a pharmacy claim problem. Each one has a different fix, and getting the reason in writing is the first step.

Before you pay cash or give up, know which row you're in.

Get it in writing. Every time.

Save the date, the exact drug and form, the rejection code, the authorization or claim number, the written reason, the name or ID of who you spoke to, and the appeal instructions.

A phone call where someone said "it's not covered" is worth almost nothing in an appeal. A written reason and rejection code are worth much more.

A trick most people miss: if the website and the phone rep disagree, ask the pharmacy to submit the exact prescription claim and read you back the rejection code. That's the plan's computer answering the exact product claim.

When more paperwork won't help

If the whole weight-loss category is excluded, submitting the same ordinary request again will not change your plan sponsor's benefit design. Redirect your energy toward:

• A coverage review or plan exception, if your plan allows one
• A different covered product or form
• HR or benefits — ask whether the category can be added at renewal
• A manufacturer cash program
• A cash-pay clinician or telehealth option, after you compare the full price

That last part is the next section, and there's a good answer in it.

How much does a GLP-1 actually cost with Express Scripts?

There is no universal Express Scripts GLP-1 price — your deductible, plan design, pharmacy, supply amount, product, and approval status all change it. Members whose plan sponsor adopted Evernorth's optional benefit may pay no more than $200 a month for Wegovy or Zepbound.

Here are the real paths. They are not in a universal cheapest-to-most-expensive order because your eligibility changes the answer.

The $200 cap most members have never heard of

In May 2025, Evernorth announced an optional benefit that limits the member's monthly cost for Wegovy and Zepbound to no more than $200 and says the amount counts toward the member's annual deductible.

The published option uses a simplified approval process and lets participating members fill through a retail network or Evernorth's EnGuide home-delivery pharmacy.

The catch is the whole story: your plan sponsor has to adopt it. It is an option, not a default. Which is exactly why the HR question above is worth asking word for word.

Sources: Evernorth's May 2025 benefit announcement and its February 2026 GLP-1 cost update, checked August 11, 2026.

Home delivery, if your plan has it

Some eligible members can get GLP-1s shipped through Evernorth EnGuide Pharmacy. Your plan sponsor must select EnGuide for it to be in your network.

Express Scripts says a new prescription takes about three to five days to reach your home after the pharmacy receives it. Refills also take about three to five days after you order them.

Two honest notes. Access depends on your plan choosing the pharmacy. And Express Scripts says plainly that no pharmacy can guarantee supply — including EnGuide. Don't cancel your retail backup until you know your order is moving.

Also worth saying: home delivery being available doesn't mean the drug is covered. Those are separate questions.

Source: Express Scripts' EnGuide Pharmacy FAQ, checked August 11, 2026.

What we won't tell you

You will find pages that quote one exact Express Scripts tier, one specific copay, or a national approval rate.

We looked for the source behind those numbers. The abbreviated national drug list has no tier column, no copay column, and no approval-rate data.

So we're leaving those blank. A number we can't trace is worse than no number, because you might plan around it.

If your plan won't pay, here's the honest ranking

Start with the manufacturer cash program for the exact FDA-approved product because it may avoid a separate telehealth membership. We earn nothing when you do that. A telehealth program is worth paying for when you need a clinician, ongoing care, or help understanding an insurance path you do not want to manage alone.

Now the part where we have a financial interest, so we'll be extra careful with it.

The honest problem with our recommendation

Ro's free insurance checker is much narrower than the Express Scripts list. It checks only the Ozempic Pen, Wegovy Pen, and Zepbound Pen. Ro says it cannot currently check insurance coverage for the Zepbound KwikPen, Foundayo pill, or Wegovy pill.

The checker also does not list Ozempic Tablets, Rybelsus, Mounjaro, Trulicity, Soliqua, or generic liraglutide. Ro's public checker page does not separately say whether its "Wegovy Pen" check includes Wegovy HD. And no three-product checker can settle whether your plan left out the whole weight-loss category.

So if your prescription is not one of the three product names on Ro's checker page, Ro's checker is not your shortest path. Use your Express Scripts account, the number on your card, and your own prescriber first. That's a real limitation and we're not going to paper over it.

And here's why the checker can still help the right person.

The current Express Scripts national list prefers both the Wegovy Pen and the Zepbound single-dose Pen. Those are two of the three products Ro says it checks. The fit is specific, not universal:

• Good fit: you are considering the Wegovy Pen or Zepbound single-dose Pen, want a free insurance report first, and may want ongoing telehealth care.
• Poor fit: you need an insurance check for a pill, Mounjaro, Rybelsus, Soliqua, generic liraglutide, or another product outside Ro's three named pens — or you need certainty that its Wegovy Pen check includes Wegovy HD.
• Also poor fit: your plan excludes the whole weight-loss category, or you already have a clinician who handles the paperwork well. You do not need to pay a membership for a service you already have.

What Ro actually costs

Ro's live pricing page showed the following on August 11, 2026:

These are Ro's posted prices, not Express Scripts copays or coverage guarantees.

Sources: Ro's live weight-loss pricing page and Ro's GLP-1 Insurance Coverage Checker, checked August 11, 2026.

What the membership buys you: access to licensed providers, ongoing care, support, and dose adjustments. The free checker contacts your insurer and sends a coverage report. Ro says the checker itself does not submit a treatment request or write a prescription.

### If one of Ro's three checked pens fits what you're looking for Ro can check insurance coverage for the Ozempic Pen, Wegovy Pen, and Zepbound Pen before you decide whether to join. It does not check the full Express Scripts list. Membership starts at $39 for the first month, then $74–$149/month depending on the plan. Medication is billed separately. Check insurance coverage and current pricing on Ro Sponsored affiliate link. Verify the live drug price, dose, plan term, refund rule, and insurance-checker scope before signing up.

Why you won't find compounded providers on this page

Some sites will offer you compounded semaglutide or tirzepatide here. We deliberately don't, for two reasons.

This page is about a list of FDA-approved medicines and who pays for them. Compounded drugs are not FDA-approved — the FDA does not review them for safety, effectiveness, or quality before they are marketed — and mixing the two categories into one coverage table would blur a line that shouldn't be blurred.

Compounded drugs can serve a medical need for some patients. They are still not generic versions of the FDA-approved products, and they are not covered products on the Express Scripts national table above.

Source: FDA Human Drug Compounding, checked August 11, 2026.

And practically: if you have useful pharmacy coverage for an FDA-approved product, you should check that benefit before being routed to a cash-pay compounded drug. Sending you away from a useful covered FDA-approved option before checking it would be a worse outcome for you and a better one for us. We'd rather have the trust.

Does Express Scripts Medicare cover GLP-1 drugs in 2026?

Medicare Part D generally cannot cover a drug when it is used only for weight loss. A separate federal demonstration fills part of that gap: from July 1, 2026 through December 31, 2027, the Medicare GLP-1 Bridge gives eligible Medicare Part D beneficiaries access to Foundayo, Wegovy, and the Zepbound KwikPen for a flat $50 copay.

If you're on Medicare, everything above is background. This is your section.

Part D can cover GLP-1s for a Part D-coverable FDA-approved use, subject to your plan's formulary and review rules. Examples include:

• Diabetes GLP-1s for type 2 diabetes
• Zepbound for moderate-to-severe obstructive sleep apnea in adults with obesity
• Wegovy to lower the risk of major cardiovascular events in adults with established cardiovascular disease and overweight or obesity
• Wegovy for noncirrhotic MASH with moderate-to-advanced liver fibrosis

The Bridge is for weight management — and CMS runs it outside the normal Part D coverage and payment flow. Part D plans do not have to opt in.

What the Bridge covers

The same-day device reversal

Put the two rulebooks side by side. Both took effect July 1, 2026.

Exactly backwards. Same active ingredient. Same date. Different program.

Here's what that means in real life. A person moving from an Express Scripts commercial plan to an eligible Medicare Part D Bridge path may need a different Zepbound device. A prescription that fit the commercial list can fail under the Bridge, and the Bridge product can fail under the commercial list.

If you're changing plans while taking Zepbound, ask your prescriber to confirm the device before the switch.

Bridge details worth knowing before you count on it

• The copay is $50 for one 28- or 30-day supply. The Bridge does not allow 60- or 90-day fills. It sits outside Part D, so the $50 does not count toward the Part D deductible or true out-of-pocket spending. Low-income subsidies, coupons, and discount programs do not lower it.
• The Bridge is not limited to people age 65 or older. CMS requires age 18 or older and enrollment in an eligible Medicare Part D plan. Eligible plan types include standalone Part D plans, most HMO or PPO Medicare Advantage drug plans, Special Needs Plans, employer or union group waiver plans, and LI NET. PACE and several less-common plan types are not eligible unless the person also has a standalone Part D plan.
• You are not eligible in 2026 if you already filled one of nine GLP-1 drugs through Part D during 2026. CMS checks Zepbound, Mounjaro, Foundayo, Rybelsus, Ozempic, Wegovy, Saxenda, Victoza, and Trulicity. A fill through an employer-group Part D supplemental benefit also counts.
• You are not eligible if you have type 2 diabetes, moderate-to-severe obstructive sleep apnea, or noncirrhotic MASH with moderate-to-advanced fibrosis — even if your current Part D plan does not cover a GLP-1 for that diagnosis.
• A clinician must submit a prior authorization and attest that the drug is for weight reduction with current and ongoing lifestyle modification. An approval lasts through December 31, 2027. Refills do not need a new prior authorization unless you switch to a different covered GLP-1.
• Zepbound KwikPen needles are not covered by the Bridge. They must be bought separately.

That diagnosis rule is a trap, and it's important. A diagnosis such as moderate-to-severe sleep apnea can make you ineligible for the flat $50 Bridge price, even when your Part D plan then makes you use its normal formulary or exception process.

Eligibility runs on three BMI tiers:

1. BMI 35 or higher on its own
2. BMI 30 or higher with heart failure with preserved ejection fraction, uncontrolled hypertension despite two medicines, or chronic kidney disease stage 3a or higher
3. BMI 27 or higher with prediabetes, a prior heart attack, a prior stroke, or symptomatic peripheral artery disease

CMS says the BMI and diagnoses are measured when GLP-1 therapy began, not only on the day the prior-authorization form is sent.

Check the government first: read the official CMS Bridge page, then use our Medicare GLP-1 Bridge eligibility guide to turn the rules into a checklist. On Medicare, a provider sales page should not be your first stop.

Does Express Scripts TRICARE cover GLP-1 drugs?

Express Scripts administers the TRICARE pharmacy benefit under a separate military drug list. TRICARE covers weight-loss medications including Wegovy and Zepbound for eligible TRICARE Prime, TRICARE Select, and premium-based plan members who meet the clinical rules, use a TRICARE network provider, and receive approved prior authorization.

Premium-based plans include TRICARE Young Adult, TRICARE Reserve Select, TRICARE Retired Reserve, and the Continued Health Care Benefit Program.

TRICARE also says Trulicity, Ozempic, Mounjaro, and Victoza remain covered for type 2 diabetes with prior authorization. Ozempic, Mounjaro, and Victoza also require a medical-necessity form for a formulary copay and military-pharmacy coverage.

Same company. Different rulebook. Nothing on the commercial list above decides your TRICARE claim.

One date matters a lot here: as of August 31, 2025, TRICARE For Life and direct-care-only beneficiaries are excluded from weight-loss medication coverage under this rule. That cutoff did not remove the diabetes benefit for people who meet the diabetes rules.

Your correct next step is the TRICARE Formulary Search Tool — look up the exact drug and form, then open the current prior-authorization or medical-necessity form it gives you.

What we actually verified

On August 11, 2026, The RX Index opened and read Express Scripts' current national drug list and exclusion list, four dated versions of the 2026 Weight Loss exclusion row, and a plan-specific Teacher Retirement System of Texas drug list. We separated what the documents prove from what they cannot prove, and we're publishing both.

Express Scripts documents opened and read on August 11, 2026:

What we could not verify, and did not pretend to know:

• Your plan. No public national document can tell us what your specific plan sponsor bought.
• One universal tier, copay, or coinsurance number. The abbreviated national list contains no tier or copay column.
• Whether prior authorization applies to one drug on your plan. The member list contains no PA codes.
• One national GLP-1 approval or denial rate. Express Scripts does not publish one in the documents reviewed here.
• Whether a pending request will be approved. Only the applicable plan can decide that claim.

Update log

Refresh rule: re-open the current national list, exclusion document, CMS Bridge guidance, TRICARE notice, and Ro pricing page before every material update. The one thing that must never go stale is the document date attached to the drug table.

Common questions

What GLP-1 does Express Scripts cover in 2026?

On the July 1, 2026 national documents: Wegovy Pens, Wegovy HD, Wegovy Tablets, the Zepbound single-dose Pen, Foundayo, and generic liraglutide appear in the weight-loss path. Ozempic, Ozempic Tablets, Rybelsus, Mounjaro, Trulicity, and Soliqua appear on the national diabetes list. Your own plan is the final answer because plan sponsors can customize or exclude coverage.

Does Express Scripts cover Wegovy?

Wegovy Pens, Wegovy HD, and Wegovy Tablets are named preferred alternatives in the current national Weight Loss row. That does not prove your plan covers Wegovy. Search the exact form in Price a Medication on your account.

Does Express Scripts cover Zepbound?

The single-dose Zepbound Pen is a named preferred alternative on the current national list. Zepbound KwikPens and Zepbound vials are excluded as of July 1, 2026. Search the exact device, not just "Zepbound," or you may get the wrong answer.

Why did my Zepbound refill stop working in July 2026?

If your prescription is for the KwikPen, the July 1 change is one possible reason: Express Scripts added Zepbound KwikPens to the excluded national list while keeping the single-dose Pen preferred. Confirm that your own plan follows that list before asking your prescriber to change the device.

Does Express Scripts cover Foundayo?

Foundayo is named as a preferred alternative in the July 1, 2026 national Weight Loss row. It did not appear in the November 2025 or April 2026 versions we reviewed. Personal coverage still depends on your plan.

Does Express Scripts cover Ozempic and Mounjaro?

Both are printed on the July 2026 national drug list. That fact does not prove your plan covers them, and the approved product and diagnosis still matter. Search the exact product in your account and ask which written policy applies.

Does prior authorization mean my drug is covered?

Not necessarily. Prior authorization is a clinical review. Formulary and benefit status decide whether the drug, form, use, and category are available under your plan. An approved authorization does not always override a benefit exclusion or product change.

Why does Price a Medication say not covered when my prior authorization is active?

The authorization may apply to a different product, device, use, or plan period. Ask whether the authorization is active for the exact National Drug Code and whether that product is still included in your benefit.

Can my employer exclude weight-loss drugs even if they're on the Express Scripts list?

Yes. The national list says it is abbreviated, does not guarantee coverage, and is not used the same way by every plan. The TRS of Texas comparison and Duke's published exclusions show how plan-specific rules can change the answer.

How much does Wegovy cost with Express Scripts?

There's no universal price — it depends on your deductible, plan design, pharmacy, product, supply amount, and approval status. Members whose plan sponsor adopted Evernorth's optional benefit may pay no more than $200 a month for Wegovy or Zepbound.

Does Express Scripts require a lifestyle program for GLP-1 coverage?

Some plans do. Express Scripts says a subset of people using weight-loss GLP-1s through EnGuide must enroll and engage in a lifestyle modification program, and that the employer or health plan chooses the requirement.

Can Express Scripts ship my GLP-1 to me?

Some eligible members can use Evernorth EnGuide Pharmacy when their plan sponsor has selected it for the network. Express Scripts says new prescriptions and refills generally take about three to five days after receipt or ordering. No pharmacy can guarantee supply.

Does Express Scripts Medicare cover weight-loss GLP-1s?

The commercial Express Scripts list does not govern Medicare. The separate Medicare GLP-1 Bridge covers Foundayo, Wegovy injection and tablets, and the Zepbound KwikPen for eligible Part D beneficiaries at a $50 copay from July 1, 2026 through December 31, 2027.

Does TRICARE cover Wegovy or Zepbound?

TRICARE says weight-loss medications including Wegovy and Zepbound are covered for eligible Prime, Select, and premium-based plan members who meet the rules and have approved prior authorization. TRICARE For Life and direct-care-only beneficiaries are excluded from the weight-loss benefit under the August 31, 2025 rule.

Can I appeal an Express Scripts denial?

A denial for missing information, the wrong product, or a misapplied rule may be resubmitted or appealed. A whole-category benefit exclusion needs a different approach, such as a coverage review, formal exception if available, a listed alternative, or a benefits discussion with the plan sponsor.

The bottom line

Four steps, in this order:

1. Read the current list for your exact drug and device. The table at the top of this page uses the July 1, 2026 documents.
2. Look up that same product in Price a Medication on your own Express Scripts account. Screenshot it.
3. Figure out which problem you have — wrong device, missing approval, drug excluded, whole category excluded, or a pharmacy claim error. They have different fixes.
4. Take the matching next step, and get everything in writing.

If you do those four things, you'll know more about your own coverage than most people ever find out — and you'll stop losing weeks to the wrong request.

This page explains public coverage documents. It is not medical advice and it cannot confirm any individual claim. Your clinician decides whether a medication is appropriate for you. Your plan decides whether and how it will pay. The products discussed here have different FDA-approved uses, warnings, contraindications, and side effects. Several carry a boxed warning about thyroid C-cell tumors. Read the FDA label for the exact product and talk to a licensed clinician.
