Certain GLP-1 weight-management drugs are now available to eligible people with Medicare for $50 per one-month supply through the Medicare GLP-1 Bridge. This temporary, nationwide program runs from July 1, 2026, through December 31, 2027, and covers Foundayo tablets, Wegovy injections or tablets, and Zepbound KwikPen only.
The Bridge is a separate CMS program, not regular Medicare Part D drug coverage. That distinction matters: the $50 copay has different cost rules from the amounts you normally pay through your Part D plan. Here’s what you need to know about eligibility, costs, and how to get started.
Who may qualify for the Medicare GLP-1 Bridge?
You must meet one of the following three body mass index (BMI) and health-condition pathways when you start GLP-1 therapy. BMI is a measure based on your height and weight.
- BMI of 35 or higher. No additional condition is listed for this tier.
- BMI of 30 or higher, plus at least one of these conditions:
- Diastolic heart failure (also called heart failure with preserved ejection fraction)
- Uncontrolled high blood pressure
- Chronic kidney disease at stage 3a or higher
- BMI of 27 or higher, plus at least one of these conditions:
- Prediabetes
- A previous heart attack or stroke
- Blocked arteries in your legs or arms (peripheral artery disease) with symptoms
These are distinct pathways. For example, a person with a BMI of 35 or higher meets the listed BMI pathway without needing one of the additional conditions in tiers two or three. A person with a BMI of 30 to 34.9 needs one of the conditions specified for tier two; the tier-three conditions are not substitutes for tier two’s list.
You must also be 18 or older and enrolled in Medicare drug coverage (Part D). This may be a standalone Part D plan or a Medicare Advantage plan that includes drug coverage.
You are not eligible for the Bridge if you already get a GLP-1 drug covered through your Part D plan, or if you have type 2 diabetes, moderate-to-severe sleep apnea, or fatty liver disease. Your Part D plan might cover GLP-1 drugs for those conditions instead. If your Part D plan already covers a GLP-1 for another covered condition, that coverage continues unchanged.
The covered products are specific: Foundayo (tablet), Wegovy (injection or tablet), and Zepbound KwikPen. The Bridge does not cover single-dose Zepbound vials or single-dose Zepbound pens. Check the official Medicare coverage page for the current eligibility questions and details.
How the $50 copay works, and what it does not do
If you qualify and your Bridge coverage is approved, you pay $50 at the pharmacy for each one-month supply. Depending on the drug, that supply is either 28 or 30 days.
The key detail is that the Bridge operates outside your regular Part D benefit. So while the copay is $50, it does not work like ordinary Part D cost-sharing. Specifically, the $50:
- Does not count toward your Part D deductible (the amount you may have to pay before your plan’s drug coverage begins).
- Does not count toward your annual Part D out-of-pocket limit or your true out-of-pocket (TrOOP) costs (the spending Medicare tracks within the Part D benefit).
- Does not appear on your Part D Explanation of Benefits (EOB) or your Medicare Summary Notice.
- Cannot be lowered by Extra Help, the Medicare program that helps eligible people with Part D costs.
- Cannot be spread across months using the Medicare Prescription Payment Plan.
In practical terms, paying $50 for a Bridge-covered supply will not build credit toward your regular Part D deductible or annual out-of-pocket limit. And if you rely on Extra Help or the Prescription Payment Plan to manage prescription expenses, those programs do not reduce or divide this Bridge copay. Keep the $50 separate from your regular Part D cost estimates when you plan your monthly budget.
How to get started
Start by discussing the Bridge with your health care provider. If the provider determines that you may qualify and prescribes a covered drug, they send the prescription to the pharmacy. When requested, the provider must complete a prior authorization (approval required before coverage is provided) and certify that the medicine is part of a lifestyle program focused on diet and exercise.
Your pharmacy may ask for your Medicare number or the last four digits of your Social Security number to process the prescription. Medicare will send you a letter confirming that your GLP-1 drug is covered through the Bridge.
Prior authorization is valid through December 31, 2027, including for refills and dose changes, unless you change GLP-1 drugs. If you switch to a different GLP-1, you may need a new approval. The program is scheduled to run through December 31, 2027; CMS extended it to collect drug-use data ahead of the potential BALANCE model in Part D.
Questions to ask before filling a prescription
A little preparation can help you understand the process and avoid surprises at the pharmacy.
Ask your provider:
- Which of the three eligibility pathways may apply to me?
- Does the prescribed product and form, such as Wegovy tablets or Zepbound KwikPen, match what the Bridge covers?
- Will you send the prescription and complete the prior authorization when requested?
- Can you certify that the medication is part of a lifestyle program focused on diet and exercise?
Confirm what to expect with your pharmacy and drug plan:
- Does the pharmacy have the prescription and the information it needs to process the Bridge claim?
- Is the prescription being processed through the Medicare GLP-1 Bridge rather than your regular Part D coverage?
- Should I expect to pay the $50 copay for this one-month supply?
The Bridge is separate from Part D, so don’t assume that the copay will show up in your plan’s usual cost records. If you need help checking your eligibility or the status of prior authorization, call 1-800-MEDICARE (1-800-633-4227); TTY users can call 1-877-486-2048.
If you have been paying cash
If you have been paying out of pocket for a GLP-1, check whether you meet the Bridge’s eligibility requirements and ask your provider about the next steps. Paying cash does not, by itself, establish that you qualify. The BMI and health-condition pathway, age, Part D enrollment, exclusions, prescription, and prior authorization requirements still apply.
If you have been getting a GLP-1 covered through Part D for another condition, that coverage continues unchanged, but you are not eligible for the Bridge while you already receive GLP-1 coverage through your Part D plan. Ask your plan or provider how your existing coverage applies before making any changes.
