Will my insurance cover a GLP-1?

Only your plan can say yes. This tells you what plans like yours tend to do, the exact questions that get a straight answer, and what to do if the answer is no.

How are you insured?
What would it be prescribed for?

Pick the main reason. Coverage often depends on it more than on the medicine.

Tell us how you are insured and what the medicine would be for. You will get what plans like yours tend to do, and the exact questions to ask.

What a prior authorization usually asks for

  • A recorded BMI with the date it was measured, at or before the start of treatment
  • Each weight-related condition, with its diagnosis
  • What you have already tried: diet, activity, a structured program, other medicines, with dates
  • Your prescriber's note on why this medicine, and the plan to review how it is working

Plans set their own forms. This list mirrors the criteria CMS publishes for the GLP-1 Bridge and the lifestyle-program requirement KFF reports, so treat it as what to have ready, not a rule.

If the answer is no

  • Work and marketplace plans: File within 180 days of the denial. The plan decides within 30 days for a medicine you have not had yet; urgent cases within 4 business days at most. If the internal appeal fails, ask in writing for an external review within 4 months. An independent reviewer decides within 45 days (72 hours if urgent), and the insurer must accept the decision. It is free under the federal process, or $25 at most under a state one.
  • Medicare Part D: Ask your plan for a redetermination within 65 days. It decides in 7 days, or 72 hours if your prescriber says waiting could harm your health. If it says no, the next step is an Independent Review Entity; the deadline is on your denial notice.

Why the reason on the prescription matters

The same molecule can be covered for one use and refused for another. Medicare law excludes drugs used for weight loss but not drugs for diabetes, heart disease or sleep apnea, and many private plans draw the same line. Wegovy is approved to lower heart risk and for MASH, Zepbound for sleep apnea, Ozempic and Mounjaro for type 2 diabetes. If one of those applies to you, it belongs on the prescription.

Medicare's GLP-1 Bridge, in full

  • $50 a 28 or 30 day fill, from 1 July 2026 to 31 December 2027. The Part D deductible does not apply, and the $50 does not count toward the $2,100 out-of-pocket cap.
  • Covers Wegovy (injection or tablets), Foundayo, and the Zepbound KwikPen only (not Zepbound single-dose pens or vials).
  • You need a Part D plan, to be 18 or older, and a prescription for weight reduction with lifestyle changes.
  • At the start: a BMI of 35 or more; or 30 or more with heart failure with preserved ejection fraction, uncontrolled high blood pressure (above 140/90 on two medicines), chronic kidney disease, stage 3a or worse; or 27 or more with prediabetes, a previous heart attack, a previous stroke, symptomatic peripheral artery disease.
  • Not for people with type 2 diabetes, moderate to severe obstructive sleep apnea, mash (fatty liver disease): they go through their Part D plan.
  • Check at medicare.gov/glp1bridge or call 1-800-MEDICARE.

Questions people ask

Does insurance cover GLP-1s for weight loss?

Sometimes. In 2025, 19% of firms with 200 or more workers covered them mainly for weight loss, rising to 43% of firms with 5,000 or more. Coverage for type 2 diabetes is far more common.

Does Medicare pay for Wegovy or Zepbound?

Part D cannot cover drugs used for weight loss by law, but it can cover Wegovy for heart risk or MASH and Zepbound for sleep apnea. For weight, the Medicare GLP-1 Bridge charges $50 a fill to eligible people from 1 July 2026 to 31 December 2027.

How long does an appeal take?

For work and marketplace plans: File within 180 days of the denial. The plan decides within 30 days for a medicine you have not had yet; urgent cases within 4 business days at most. If the internal appeal fails, ask in writing for an external review within 4 months. An independent reviewer decides within 45 days (72 hours if urgent), and the insurer must accept the decision. It is free under the federal process, or $25 at most under a state one.
