Starting July 1, 2026, Medicare will cover weight loss drugs.
Medicare will cover weight loss drugs for eligible Part D beneficiaries through December 31, 2027. This is a major shift. Medicare previously covered GLP-1s only when prescribed for type 2 diabetes, cardiovascular disease risk reduction, or moderate to severe obstructive sleep apnea. It did not cover them for obesity or weight management alone.
That changes with the Medicare GLP-1 Bridge program. Eligible Medicare Part D enrollees — including many Medicare Advantage plans with drug coverage — can now access GLP-1 medications for a $50 monthly copay.
It depends on which coverage pathway applies to you.
Through the Medicare GLP-1 Bridge: You pay a flat $50 per monthly supply, every fill, regardless of which phase of your Part D benefit you're in.
Through Medicare Part D: Each Medicare part D plan uses a list of approved drugs (drug formulary) which may differ from plan to plan. Your cost depends on your specific plan, your diagnosis, your deductible (up to $615 in 2026), and which tier the medication falls on in your plan's formulary.
Understand your out-of-pocket costs. Coverage doesn't mean free. Your cost will depend on your specific plan, diagnosis, deductible, and formulary tier. See the full comparison below.
To be eligible under the Medicare GLP-1 Bridge program, you must be enrolled in Medicare part D and meet at least one of the following BMI-based criteria. If you have questions about your specific coverage options you should contact 1-800-MEDICARE (1-800-633-4227) or your local State Health Insurance Assistance Program. Your knownwell clinician can also help assess your options at your visit. Book a visit with a knownwell clinician.

Prior authorization will still be required.
If you have a coverable condition under Part D, the Medicare GLP-1 Bridge programmay not apply.
For example, if you currently have an approved prior authorization through Part D for Zepbound prescribed for moderate to severe sleep apnea, Wegovy for cardiovascular risk reduction or noncirrhotic metabolic dysfunction-associated steatohepatitis (MASH), or all FDA-approved medications for treating Type 2 Diabetes (Ozempic, Mounjaro, etc.), the Medicare GLP-1 Bridge program will not cover your medication.
For these indications, drug coverage will continue under your standard Part D plan’s formulary.
Only Medicare Part D beneficiaries who are enrolled in eligible plan typesand meet the Medicare GLP-1 Bridge Clinical Criteria above will be eligible.
Eligible plan types: To qualify for coverage, Medicare beneficiaries must be enrolled in a standalone prescription drug plan (PDP) or Medicare Advantage (MA) coordinated care plan (i.e., HMO, HMOPOS, and Local and Regional PPO plans) that offers prescription drug coverage (MA-PD plans).
Part D beneficiaries in Special Needs Plans (SNPs), employer/union group waiver plans (EGWPs), and the Limited Income Newly Eligible Transition (LI NET) program are eligible to participate.

If you have Medicare and are prescribed a GLP-1 medication, your cost and coverage will depend on which pathway applies to you — the Medicare GLP-1 Bridge or your Part D plan.

Medicare part D helps cover the cost of prescription drugs. Part D is optional and offered to everyone who qualifies for Medicare. There are two ways to get Medicare Part D prescription drug coverage:
Part D is offered through private insurance companies approved by the federal government. Drug costs and coverage may vary from plan to plan.
Foundayo® (orfoglipron) is the first oral, non-peptide GLP-1 receptor agonist approved by the FDA for chronic weight management in adults with obesity or excess weight and a related health condition.
Unlike injectable GLP-1s, orfoglipron is a pill taken once daily without food restrictions. In clinical trials, patients taking orfoglipron lost an average of 7.9–8.7% of their body weight over 36 weeks.
Wegovy® is a once-weekly injectable semaglutide approved by the FDA for chronic weight management. It works by mimicking GLP-1, a hormone that regulates appetite and blood sugar, helping patients feel fuller longer and eat less over time.
In the STEP clinical trials, adults using semaglutide lost an average of 15% of their body weight over 68 weeks. Wegovy® is also FDA-approved to reduce the risk of serious cardiovascular events in adults with cardiovascular disease and obesity.
The oral formulation of semaglutide offers the same active ingredient as the Wegovy® injection in a once-daily pill. It's an option for patients who prefer not to self-inject.
Clinical data shows meaningful weight reduction comparable to other GLP-1 formulations, with the added convenience of an oral format.
Zepbound® is a once-weekly injectable tirzepatide that works on two hormone pathways — GLP-1 and GIP — making it the first dual agonist approved by the FDA for weight management.
In the SURMOUNT clinical trials, patients lost an average of 20.9% of their body weight over 72 weeks at the highest dose, the most of any approved obesity management medication to date. Zepbound® is also FDA-approved for moderate-to-severe obstructive sleep apnea in adults with obesity.

The Medicare Bridge program covers patients based on BMI and clinical criteria:
• BMI 35 or higher — no additional diagnosis required
• BMI 30 or higher — with heart failure with preserved ejection fraction (HFpEF), uncontrolled hypertension, or chronic kidney disease (stage 3a+)
• BMI 27 or higher — with pre-diabetes, prior heart attack (MI), prior stroke, or symptomatic peripheral artery disease
Your knownwell clinician will confirm which criteria apply at your visit.
Possibly, yes. If you were already prescribed a GLP-1 for weight management before July 1, 2026, you may still qualify — even if your current BMI has changed since you started. Your knownwell clinician will attest in the prior authorization that you met the eligibility criteria when you first began the medication.
For example, if you started a GLP-1 in 2024 with a BMI of 37 but now have a BMI of 33 due to weight loss, your clinician can document the original qualifying BMI to support your PA.
No, not yet. The current coverage with the Medicare Bridge program is running through December 31, 2027. After that, Centers for Medicare & Medicaid Services will evaluate outcomes and make a decision on extending coverage.
Advocates and the obesity medicine community are pushing for permanent coverage through legislation like the Treat and Reduce Obesity Act (TROA).
Yes, if your Medicare Advantage plan includes drug coverage (called an MA-PD plan). Most Medicare Advantage plans include prescription drug coverage, which means you are eligible for the Medicare GLP-1 Bridge program if you meet the clinical criteria.
Check with your plan directly to confirm. If you're unsure whether you have a standalone Part D plan or Medicare Advantage with drug coverage, look at your plan card or call 1-800-MEDICARE.

If your authorization is denied because you don't meet the program's coverage criteria, we offer affordable cash-pay options for weight management medications.
If your prior authorization is incorrectly denied, we can resubmit or appeal on your behalf. Your clinician can discuss all your treatment options and help you find the best path forward for your care.
Yes — starting July 1, 2026, for eligible patients who meet the BMI criteria above, even without a diabetes diagnosis. This is the major shift: previously, Medicare coverage required a diabetes or cardiovascular diagnosis. The Bridge program extends coverage to obesity management as a standalone indication.
This change comes through the Medicare GLP-1 Bridge program, a demonstration authorized by the CMS Innovation Center (CMMI) under the Social Security Act's Section 1115A. The program is designed to test whether covering these medications reduces hospitalizations, improves outcomes, and lowers long-term Medicare costs.
The Treat and Reduce Obesity Act (TROA), long advocated by obesity medicine specialists, has pushed for exactly this kind of coverage expansion for years. This demonstration is the first concrete step toward making it a permanent benefit.
Through the Medicare GLP-1 Bridge, you pay a flat $50 per monthly supply. Through standard Medicare Part D, your cost depends on your specific plan, your diagnosis, your deductible, and which tier the medication falls on in your plan's formulary.
Once you get started with knownwell, our team can help you understand which pathway applies to you and what to expect for your costs.
Medicare covers GLP-1s like Wegovy for certain clinical indications. The Bridge program is expanding the list of covered medications. The preferred medication depend on your diagnoses and specific plan's drug formulary.
For the Bridge Program, Wegovy and Zepbound are covered when prescribed for weight management. Other drugs like Ozempic or Mounjaro may be covered through your part D plan, but specific coverage varies by plan.
