Does Centene Ambetter Cover Wegovy? Medicare Advantage Coverage Guide 2026
Medicare Advantage enrollees on Ambetter Medicare (administered by Centene Corporation) often ask whether their plan covers Wegovy (semaglutide 2.4mg). Here’s the overview: coverage depends on several plan-specific factors.
Centene Ambetter’s Formulary Position on Wegovy
Ambetter Medicare operates with a Part D formulary that tiers medications based on coverage level. For the 2026 plan year, Wegovy is typically classified as Tier 4 (Specialty) on most Centene Ambetter plan designs.
Cost implications:
- Cost-sharing: 25%-33% coinsurance based on plan variant and drug tier
- Prior authorization: Mandatory — a PA request is needed
- Quantity limits: May apply — typically one pen/month
- Step therapy: Might need failed trial of first-line therapies first
In the donut hole phase, you’ll owe a larger share before catastrophic coverage applies.

- Centene Ambetter typically will approve Wegovy when prescribed for its FDA-approved indication
