SilverScript (Aetna Medicare Rx) Part D Review 2026

CVS Health subsidiary; ~5M Part D enrollees. Strong formulary depth for brand-name and specialty drugs; CVS Pharmacy preferred network is broad in most metros. Best for enrollees on multiple brand or specialty medications where formulary breadth matters more than the lowest possible monthly premium.

CVS Health / Aetna All 50 states + DC SmartSaver, Choice, Plus PDPs Broad brand & specialty formulary
★★★★★ 4.9/5 from Medicare-eligible callers nationwide

Quick verdict

Best for: Medicare enrollees on multiple brand-name medications, specialty drugs (oncology, MS, hepatitis C, autoimmune, GLP-1), or complex polypharmacy regimens. SilverScript's formulary depth typically produces lower total annual cost than cheaper-premium competitors when brand drugs are involved.

Not for: generic-heavy enrollees who could get equivalent coverage on Wellcare Value Script at a lower premium. Always compare via Medicare.gov Plan Finder with your actual prescription list.

Strengths

  • Comprehensive formulary — strongest brand and specialty drug coverage among major standalone Part D carriers.
  • Broad CVS preferred pharmacy network.
  • CVS Specialty Pharmacy for specialty drug fulfillment.
  • Integration with Aetna MA for coordinated benefits.
  • Three plan tiers let enrollees pick the right premium/coverage trade-off.

Watchouts

  • Higher monthly premiums than Wellcare's value plans — rarely $0.
  • CVS-direct steering on the SmartSaver plan may inconvenience non-CVS users.
  • Prior authorization on some specialty drug categories.
  • Plan tier confusion — three plans with different formularies can complicate comparison.
