Medicare coverage for certain GLP-1 medications for weight loss is available through the temporary Medicare GLP-1 Bridge program as of September 20, 2026. Eligible beneficiaries with Medicare Part D can pay $50 for a one-month supply of an approved medication. Coverage began July 1, 2026, and is scheduled to continue through December 31, 2027.
Coverage is not automatic. You must have qualifying Medicare drug coverage, meet the BMI and health-condition requirements, use the medication for weight management, and obtain prior authorization from your healthcare provider.

Which GLP-1 Medications Does Medicare Cover for Weight Loss?
The Medicare GLP-1 Bridge covers these medications when they are prescribed to reduce excess body weight and maintain weight reduction:
- Foundayo tablets
- Wegovy injection or tablets
- Zepbound KwikPen
The Bridge does not cover single-dose Zepbound vials or single-dose Zepbound pens. The list of covered products may change during the program.
Who Qualifies for Medicare GLP-1 Weight-Loss Coverage?
To qualify, you must be at least 18, have eligible Medicare drug coverage, and meet one of these BMI and medical-condition combinations:
| BMI when GLP-1 treatment began | Additional requirement |
|---|---|
| 35 or higher | No additional condition listed by CMS |
| 30 or higher | Heart failure with preserved ejection fraction, uncontrolled hypertension, or stage 3a-or-higher chronic kidney disease |
| 27 or higher | Prediabetes, previous heart attack, previous stroke, or symptomatic peripheral artery disease |
Your provider must also confirm that you are using the GLP-1 medication alongside lifestyle changes, including nutrition and physical activity. CMS uses the BMI recorded when treatment began, not necessarily your current BMI.
What Medicare Drug Coverage Do You Need?
The Medicare GLP-1 Bridge generally requires one of the following:
- A standalone Medicare Part D prescription drug plan
- A Medicare Advantage plan with prescription drug coverage, known as an MA-PD plan
- An eligible Special Needs Plan
- An eligible employer or union group waiver plan
- The Limited Income Newly Eligible Transition program
Original Medicare Part A and Part B by themselves are not enough for the Bridge. You must have qualifying Medicare drug coverage.
How Much Does Medicare GLP-1 Coverage Cost?
Eligible beneficiaries pay $50 at the pharmacy for a 28- or 30-day supply, depending on the medication. The payment is separate from the regular Part D benefit.
The $50 copayment:
- Does not count toward the Part D deductible
- Does not count toward the Part D annual out-of-pocket limit
- Does not appear on the Part D Explanation of Benefits
- Cannot be reduced through Medicare Extra Help
- Cannot be spread across several months through the Medicare Prescription Payment Plan
When Will Medicare Cover a GLP-1 Through a Regular Part D Plan?
Regular Medicare Part D coverage may apply when a GLP-1 medication is prescribed for a Medicare-covered medical condition instead of weight loss alone. CMS identifies type 2 diabetes, moderate-to-severe obstructive sleep apnea, and certain metabolic dysfunction-associated steatohepatitis indications as conditions that should be handled through the beneficiary's Part D plan.
Coverage still depends on the plan's formulary, prior authorization rules, and medical requirements.
If you already receive a GLP-1 through Part D, you generally cannot switch to the $50 Medicare GLP-1 Bridge for weight management. Your existing Part D coverage should continue to handle that prescription.
Who Is Not Eligible for the Medicare GLP-1 Bridge?
You may not qualify if:
- You do not have eligible Medicare Part D coverage
- You are younger than 18
- Your BMI is below the applicable threshold
- You do not have a qualifying condition when one is required
- You already receive a GLP-1 through your Medicare drug plan
- The prescription is for an indication that should be covered through your regular Part D plan
- Your Medicare plan type is excluded from the Bridge program
The Bridge does not replace Medicare Part D. If you need prescription drug coverage, you may need to enroll in a qualifying Part D plan during an available enrollment period.
How to Apply for Medicare GLP-1 Coverage
- Check that you have qualifying Part D coverage.
- Ask your healthcare provider whether you meet the BMI and medical requirements.
- Have your provider prescribe an eligible medication for weight management.
- Take the prescription to the pharmacy.
- Complete prior authorization if the pharmacy or Bridge program requests it.
- Confirm that your provider documents diet, physical activity, and other lifestyle support.
CMS says the pharmacy claim generally starts the prior-authorization process. Your provider may need to submit documentation confirming your BMI, qualifying conditions, treatment purpose, and lifestyle program.
Bottom Line
If you think you qualify, ask your healthcare provider to verify your BMI, medical history, treatment purpose, and prior-authorization requirements before the prescription reaches the pharmacy. You can also call 1-800-MEDICARE to confirm whether your plan is part of the Medicare GLP-1 Bridge.
