Medicare GLP-1 Bridge Eligibility: 6 Checks Before You Call

To qualify for the Medicare GLP-1 Bridge you need an eligible type of Medicare drug coverage, you must be 18 or older, and your BMI at the start of GLP-1 treatment has to fit one of three paths (35+, or 30+ or 27+ with certain conditions). You also can't have type 2 diabetes, moderate-to-severe sleep apnea or noncirrhotic fatty liver disease, which route you to your regular Part D plan. Below are six checks to run, plus a fill-in sheet so your call with the plan, pharmacy or prescriber is short.

If you need the basics first (what the Bridge is, the $50 copay, the dates), start with our Medicare GLP-1 Bridge overview. This page is the hands-on part.

Who is eligible for the Medicare GLP-1 Bridge?

CMS and Medicare.gov list the rules in a few places. Here they are as six yes/no checks. You need a "yes" on 1, 2, 5 and 6, and a "no" on 3 and 4.

☐ 1. Do you have an eligible type of Medicare drug coverage?

You need Medicare drug coverage, and the type of plan matters. For 2026, CMS lists:

Eligible	Not eligible (unless you also have a standalone Part D plan)
Standalone Part D plans (PDPs)	Medicare Advantage private fee-for-service (PFFS)
Medicare Advantage HMO, HMO-POS, local or regional PPO plans with drug coverage	Cost plans
Special Needs Plans (SNPs)	Prepayment plans
Employer/union group plans (EGWPs)	PACE
LI NET	Fallback and religious fraternal benefit plans

Where to find it: the front of your plan card, your Evidence of Coverage, or your Medicare.gov account. If your card says "PFFS," check the right-hand column before going further.

Open enrollment heads-up: Medicare Open Enrollment runs October 15 – December 7. If you're thinking about switching plans for 2027, check that the new plan type is still on the eligible side.

☐ 2. Are you 18+ and does your starting BMI fit one of the three paths?

CMS measures BMI at the start of GLP-1 therapy, even if you started before July 1, 2026 or before you had Part D. There are three ways in:

Path	BMI at start of GLP-1 therapy	Plus at least one of these
A	35 or higher	Nothing else needed
B	30 or higher	Heart failure with preserved ejection fraction (diastolic heart failure); uncontrolled high blood pressure (above 140/90 despite two blood-pressure medicines, per the CMS form); or chronic kidney disease stage 3a or higher
C	27 or higher	Prediabetes (by ADA criteria); previous heart attack; previous stroke; or symptomatic peripheral artery disease

What to dig up: the date you started your first GLP-1 and the height and weight recorded around then. The CMS form tells prescribers that if your BMI has dropped since you started, they should pick your initial BMI. Today's number isn't the one that counts.

☐ 3. Do you have a condition that sends you to Part D instead?

The Bridge excludes people with type 2 diabetes, moderate-to-severe obstructive sleep apnea or noncirrhotic MASH (fatty liver disease), even if they meet the BMI criteria. That isn't necessarily bad news. Medicare.gov notes your Part D plan may cover GLP-1s for those conditions. The CMS prior authorization form adds one more: if the medicine is prescribed to lower the risk of heart attack and stroke in someone with established cardiovascular disease, the request goes to the Part D plan. CMS also says it may check submitted information against Medicare data, for example whether you have a type 2 diabetes diagnosis. Our Bridge vs Part D guide explains that path.

☐ 4. Are you already getting a GLP-1 through your Part D plan?

If your Part D plan already covers your GLP-1, you're not eligible for the Bridge. CMS also tells pharmacies that if someone fills a GLP-1 through Part D, later Bridge refills will be rejected. Don't experiment with "let's try it both ways" at the counter.

☐ 5. Is your prescription for a covered product?

Only Wegovy (pen or tablet), Foundayo, and the Zepbound KwikPen count. Zepbound single-dose vials and single-dose pens don't. If your current prescription is for one of those, talk to your prescriber about whether a different format makes sense. That decision belongs to them.

☐ 6. Can your prescriber sign the attestation?

Your prescriber has to certify, under penalty of perjury, that the medicine is prescribed to reduce and maintain body weight alongside ongoing lifestyle changes, including structured nutrition and physical activity. There's no separate program certificate to upload, but the attestation has to be true. Your prescriber doesn't need to be enrolled in Medicare, but they can't be on Medicare's Preclusion List.

What to gather before you call: a fill-in sheet

Copy this into your notes app or print it.

Item	Your answer
Medicare Number (or last 4 of SSN for the pharmacy)
Drug plan name and type (PDP, HMO, PPO, SNP…)
Date I started my first GLP-1
Height and weight on that date / BMI
Qualifying path (A, B or C) and condition, if B or C
Type 2 diabetes, moderate-to-severe sleep apnea or MASH? (Y/N)
Currently filling a GLP-1 through Part D? (Y/N)
Exact product and strength prescribed
Prescriber name, office phone, fax
Pharmacy name and phone

Handy to keep: if you log weight in an app, export or screenshot the entries around your start date. GLPily keeps your weight history and shot or pill log together, which makes "when did I start, and what did I weigh?" easy to answer.

How the process actually runs

This is the order CMS describes for providers and pharmacies. Knowing it helps you spot where things are stuck:

1. Prescription goes to the pharmacy first. If the prescriber submits the prior authorization before the pharmacy runs a claim, the system returns "patient not found."
2. The pharmacy submits a claim to the Bridge. It doesn't need a Part D denial first.
3. A prior authorization request goes to your prescriber, usually within 24–72 hours. If nothing arrives after 72 hours, the prescriber can download the fax form from CMS.
4. A decision comes within 72 hours of submission, sent to the prescriber. You get the decision by mail.
5. Once approved, it's good through December 31, 2027, including refills and dose changes, unless you switch to a different GLP-1.

If the answer is no

There's no formal appeals process for the Bridge. If the denial came from wrong or incomplete information (an old BMI, a missing condition, a typo), your prescriber can resubmit the form with corrected or new information. If you simply don't meet the criteria, ask your prescriber whether a Part D path applies for another approved use, and compare plans during open enrollment. Our guide to reading a formulary helps with that comparison.

Common questions

Does Medicare Advantage qualify for the GLP-1 Bridge?

Many plans do. Medicare Advantage HMO, HMO-POS and PPO plans with drug coverage, Special Needs Plans and employer group plans are eligible. Private fee-for-service, cost, PACE and a few other plan types aren't, unless you also have a standalone Part D plan.

My BMI is lower now than when I started. Do I still qualify?

CMS applies the BMI criteria at the start of GLP-1 therapy, including for people who started before July 1, 2026 or before enrolling in Part D. Have the records from your start date ready.

Who submits the prior authorization?

Your prescriber does, after the pharmacy runs a claim. The CMS form says only prescribing clinicians can submit it, so you can't send it yourself. CMS strongly encourages electronic prior authorization; fax is also accepted.
