Medicare Coverage Rules for Wegovy
Medicare Part D and Medicare Advantage plans may cover Wegovy only when prescribed for a covered medical condition, such as obesity or weight-related health issues, and when the drug is on the plan's formulary. Original Medicare (Part A and Part B) generally does not cover prescription drugs for weight loss, including Wegovy, unless used for an accepted medical indication like reducing cardiovascular risk in certain patients. Coverage depends on the specific plan, formulary tier, and whether the prescribing provider meets Medicare requirements. For details on Medicare drug coverage rules, see the official Medicare.gov page on Part D coverage.
Medicare Advantage plans, offered by private insurers, can set their own rules for Wegovy coverage, including prior authorization, step therapy, or quantity limits. Some plans may require documentation of obesity-related conditions such as type 2 diabetes, high blood pressure, or sleep apnea before approving coverage. Copayments, coinsurance, and deductibles vary widely by plan, so checking the plan's formulary and pharmacy network is essential.

Eligibility and Requirements for Medicare to Pay for Wegovy
Medical Necessity and Diagnosis Criteria
Medicare is more likely to cover Wegovy when the drug is deemed medically necessary for a beneficiary with a body mass index (BMI) of 30 or higher, or a BMI of 27 or higher with at least one weight-related comorbidity. Coverage often requires documentation from a healthcare provider showing that other weight management treatments have been tried or are not appropriate. Medicare Part D plans may require prior authorization, meaning the prescriber must submit clinical evidence supporting the need for Wegovy before the plan will approve coverage.
Documentation and Provider Guidelines
Prescribers must follow Medicare guidelines for obesity screening, counseling, and treatment when requesting Wegovy coverage. This often includes records of previous weight loss attempts, medical history, and ongoing monitoring plans. Medicare Advantage plans may require the prescribing provider to be in-network and to use a preferred pharmacy or specialty pharmacy network for Wegovy dispensing.

Costs and Alternatives if Medicare Does Not Cover Wegovy
Typical Out-of-Pocket Costs with Medicare Part D
When Medicare Part D covers Wegovy, costs depend on the plan's formulary tier, deductible, and pharmacy network. Brand-name drugs like Wegovy often fall into higher tiers, leading to coinsurance rates of 25 to 33 percent or higher after the deductible is met. Beneficiaries in the coverage gap, commonly called the donut hole, may face higher costs until they reach catastrophic coverage. Manufacturer savings programs or copay cards may help lower out-of-pocket expenses for eligible patients.
Alternative Weight Management Options Covered by Medicare
If Medicare does not cover Wegovy, beneficiaries can access alternative weight management services, including intensive behavioral therapy for obesity, which is covered under Medicare Part B when provided by a primary care provider. Medicare also covers medical nutrition therapy for beneficiaries with diabetes or renal disease. Some Medicare Advantage plans offer additional wellness benefits, fitness programs, or telehealth weight management services that may complement or substitute for medication-based treatment.
