Medicare & GLP-1

Medicare and GLP-1 Medications: A Plain-English Guide for 2026

Last updated: May 28, 2026 · Reading time: about 8 minutes

The short version

• From July 1, 2026 through December 31, 2027, a CMS demonstration called the Medicare GLP-1 Bridge gives eligible Part D members access to certain GLP-1 weight-loss medications.
• Eligible members pay a flat $50 per month — the same at any dose — versus the $1,000+ these drugs otherwise cost.
• Covered drugs are Wegovy (injection and tablets), Zepbound (KwikPen), and Foundayo, for weight management. (Diabetes GLP-1s like Ozempic are covered through a separate path.)
• You must be in a Part D or Medicare Advantage drug plan and meet a BMI tier, and your doctor submits a prior authorization to CMS — not to your plan.
• The $50 does not count toward your deductible or the annual out-of-pocket cap. Brand-name only — compounded versions aren't covered.
• Always verify the latest details with Medicare.gov or CMS.

What changed in 2026

For years, Medicare did not cover GLP-1 medications like Wegovy^®, Zepbound^®, and Foundayo^® when prescribed for weight management. They were only covered when prescribed for type 2 diabetes (under different brand names like Ozempic^® or Mounjaro^®). This left millions of seniors with obesity-related health conditions paying $1,000 or more per month out of pocket — or going without.

Beginning July 1, 2026, that changes — through a time-limited CMS demonstration called the Medicare GLP-1 Bridge. Running from July 1, 2026 through December 31, 2027, the Bridge gives eligible Medicare Part D members access to specific GLP-1 weight-loss drugs — Wegovy^®, Zepbound^®, and Foundayo^® — for a flat $50 per month, no matter the dose.

Importantly, the Bridge is a separate, centrally-run program — not a change to your plan's normal benefit. It operates outside the regular Part D flow: your prescriber submits a prior authorization directly to CMS(administered through Humana, which runs Medicare's LI NET program), and CMS approves or denies it. Your Part D plan does not have to opt in for you to use it.

Who qualifies

To use the Medicare GLP-1 Bridge, you generally need all three of the following:

1
You are enrolled in Medicare Part D.
This includes standalone Part D plans and Medicare Advantage plans with prescription drug coverage (MA-PD). Original Medicare without a drug plan can't access the Bridge.
2
You meet one of the three BMI tiers.
The Bridge uses a tiered system based on body mass index (BMI) plus, at lower BMIs, a related health condition:
- Tier 1 — BMI 35 or higher. No additional condition required.
- Tier 2 — BMI 30 or higherwith one of: heart failure (preserved ejection fraction), high blood pressure that isn't controlled on two or more medications, or chronic kidney disease (stage 3a or higher).
- Tier 3 — BMI 27 or higher with one of: prediabetes, a previous heart attack, a previous stroke, or symptomatic peripheral artery disease.
Your doctor measures and documents these on the prior authorization. Note: type 2 diabetes, sleep apnea, and high cholesterol are noton the Bridge's qualifying-condition list for weight-loss use.
3
Your prescriber submits a prior authorization to CMS.
Unlike a normal Part D drug, the request goes to CMS's central processor (run by Humana through the LI NET program) — not to your own plan. CMS reviews it and approves, denies, or asks for more information.

Important: These criteria come from CMS's published Bridge rules and can be updated. Final eligibility is confirmed when CMS reviews your prior authorization. Always verify the current criteria at CMS.gov or with your plan before scheduling appointments.

How the $50 copay actually works

Under the Bridge, the $50 is a true flat copay set by CMS: you pay $50 for a one-month supply, and it stays $50 even as your dose increases over time. That predictability is the whole point of the program.

A few things that surprise people:

It's the same in every coverage phase.Unlike a normal Part D drug, the $50 doesn't change based on whether you've met your deductible.
It does not count toward your deductible or toward the annual Part D out-of-pocket cap ($2,100 in 2026). The Bridge is accounted for outside the regular Part D benefit.
Extra Help can't be applied to it.If you receive the Part D low-income subsidy (Extra Help), it doesn't lower the $50 Bridge copay further.

So for most people the math is simple: about $50 a month for a covered GLP-1, for as long as you stay eligible and the demonstration runs (through December 31, 2027).

What you need to do

Step 1 — Confirm you have Part D coverage and check your tier

Make sure you're enrolled in a Part D or Medicare Advantage drug plan — the Bridge works regardless of which plan you have, since CMS runs it centrally and plans don't need to opt in. Then review the three BMI tiers above to see which one you may fall under.

Step 2 — Schedule a visit with your primary care doctor

Bring documentation of your weight history, current health conditions, and any prior weight-loss attempts. Your doctor needs this to fill out the prior authorization form accurately. Ask specifically whether they have experience with GLP-1 prior authorizations under Medicare.

Step 3 — CMS reviews the prior authorization

Because the Bridge runs through CMS's central processor (Humana, via the LI NET program), the prior authorization is reviewed there rather than by your own Part D plan. If it's approved, you can fill the prescription at a participating pharmacy. If it's denied or needs more information, work with your doctor to add documentation and resubmit. See the further reading section below for more on appeals.

Step 4 — Fill at a participating pharmacy

Once approved, your prescription goes to a pharmacy that accepts your Part D plan. Major chains (Walgreens, CVS, Walmart, Costco) generally participate. Independent pharmacies may or may not — check first.

Questions seniors actually ask

Which GLP-1 drugs does the Medicare GLP-1 Bridge cover?

For weight management, the Bridge covers Wegovy (injection and tablets), Zepbound (KwikPen), and Foundayo. Diabetes GLP-1 medications like Ozempic and Mounjaro are covered through Medicare's regular coverage, not the Bridge.

How much will I pay, and how long does the Bridge last?

A flat $50 for a one-month supply, the same at any dose. It does not count toward your Part D deductible or the annual out-of-pocket cap. The demonstration runs from July 1, 2026 through December 31, 2027.

Can I use a compounded version to save money?

No — compounded semaglutide or tirzepatide is not covered. Only the FDA-approved brand-name medications above. Using a compounded version means paying out of pocket and losing the $50 Bridge price.

What if I am on Medicare Advantage instead of Original Medicare?

If your Medicare Advantage plan includes prescription drug coverage (an MA-PD plan), you are eligible for the Bridge just like someone with a standalone Part D plan.

Will my doctor know about this?

Many primary care doctors are still learning the Bridge's details — especially that the prior authorization goes to CMS rather than your Part D plan. Bring printed information to your appointment.

What if I am denied?

Work with your doctor to add documentation and resubmit, and use your appeal rights. Many initial denials are overturned once additional documentation is provided.
