Does SilverScript Cover Rybelsus? Medicare Advantage Coverage Guide 2026
Seniors on Medicare Advantage with SilverScript Part D (from CVS Health/Aetna) frequently want to know whether their plan covers Rybelsus (oral semaglutide). In brief: coverage depends on your plan’s formulary tier, Part D structure, and medical indication.
SilverScript’s Formulary Position on Rybelsus
SilverScript Part D uses a drug formulary that categorizes medications based on coverage level. Currently, Rybelsus is generally placed on Tier 5 (Non-preferred specialty) for typical SilverScript plan designs.
Cost implications:
- Cost-sharing: $100–$300+ depending on plan variant and drug tier
- Prior authorization: Mandatory — clinical documentation must be provided
- Quantity limits: Often enforced — limited to FDA-recommended dosing
- Step therapy: May require failed trial of first-line therapies first
In the donut hole phase, enrollees pay 25% coinsurance until catastrophic coverage kicks in.
Coverage for FDA-Approved vs. Off-Label Use
For type 2 diabetes (FDA-approved):
- SilverScript typically will authorize Rybelsus with appropriate documentation
- PA criteria: HbA1c levels, prior medication history
- Coverage is more consistent when used on-label
For weight loss (for chronic weight management):
- Original Medicare Part D excludes anti-obesity medications for weight loss alone
- That said: recent CMS guidance expanded formulary inclusion rules for weight management medications
- SilverScript could provide supplemental benefits that extend to weight management medications — review your plan’s specific formulary
