Does Medicare cover GLP-1 medications?
medicare
Medicare is the federal health insurance program for adults 65+ and certain younger people with disabilities.
Medicare Part D covers GLP-1s for FDA-approved diabetes use only. Medicare does NOT cover GLP-1 medications for weight loss (current law excludes anti-obesity drugs from Part D, though the Treat and Reduce Obesity Act has been introduced to change this).
Medicare coverage by drug
- Not coveredWegovysemaglutide
Medicare does NOT cover Wegovy for weight loss. Federal law currently excludes anti-obesity medications from Medicare Part D. The Treat and Reduce Obesity Act, introduced in Congress, would change this — as of 2026 it has not become law.
- Not coveredZepboundtirzepatide
Same statutory exclusion as Wegovy. Medicare does not cover Zepbound for weight loss.
- CoveredOzempicsemaglutide
Medicare Part D covers Ozempic for FDA-approved type 2 diabetes use. Most plans require prior authorization with documented T2D diagnosis.
- CoveredMounjarotirzepatide
Medicare Part D covers Mounjaro for type 2 diabetes with prior authorization.
- Not coveredSaxendaliraglutide
Medicare does not cover Saxenda for weight loss (same statutory exclusion as Wegovy/Zepbound).
Reminder: coverage varies by plan
Medicare offers many plan designs. The same medication can be covered under one Medicare plan and excluded from another. Always confirm with your specific plan's formulary or call the number on your insurance card before assuming coverage.
Frequently asked
Does Medicare cover GLP-1 medications for weight loss?+
Medicare Part D covers GLP-1s for FDA-approved diabetes use only. Medicare does NOT cover GLP-1 medications for weight loss (current law excludes anti-obesity drugs from Part D, though the Treat and Reduce Obesity Act has been introduced to change this). GLP-1 coverage at Medicare varies plan by plan. For Wegovy and Zepbound (weight-loss indications), expect prior authorization at minimum, with formal documentation of BMI and previous lifestyle interventions. For Ozempic and Mounjaro (type 2 diabetes), coverage is generally easier when prescribed for diabetes.
Does Medicare require a prior authorization for Wegovy or Zepbound?+
Yes, prior authorization (PA) is the norm for weight-loss GLP-1s across Medicare plans. A PA typically requires documented BMI ≥30 (or ≥27 with a comorbidity), prior attempts at structured weight loss, and sometimes step-therapy through cheaper alternatives. Your prescriber's office files the PA — the typical turnaround is 3-15 business days.
How do I check if my specific Medicare plan covers a drug?+
Three steps: (1) Log into your Medicare member portal and search the drug formulary by name. (2) Call the member services number on your insurance card. (3) Ask your prescriber to submit a benefits inquiry. Plan designs differ widely within Medicare — what's covered for one member may not be covered for another.
What if Medicare denies my GLP-1 prior authorization?+
Three options: (1) Appeal — most plans grant an appeal that adds physician peer-to-peer review; your prescriber can request this. (2) Switch indication if clinically appropriate (e.g., if you have prediabetes and BMI ≥30, your physician may have different coverage paths). (3) Use manufacturer direct-pay (NovoCare, LillyDirect) which doesn't depend on insurance approval. Federal program coverage policies follow CMS rules and have less plan-by-plan variability — appeals are still available.
Are compounded GLP-1s covered by Medicare?+
Generally no. Most insurance plans, including Medicare, do not cover compounded semaglutide or tirzepatide regardless of pharmacy. As of 2026, the FDA is winding down large-scale compounding, so coverage questions are increasingly moot — most patients are transitioning to branded GLP-1s or manufacturer direct-pay programs.
