Common Denial Patterns

  • Formulary denials directing members to preferred (often CVS-owned) alternatives
  • Step therapy requirements before covering brand-name or specialty drugs
  • Prior authorization denials for specialty medications and high-cost drugs
  • Quantity limit denials exceeding PBM-defined dosage limits

Appeal Best Practices

  1. 1Request a Coverage Determination or formulary exception — not just an appeal
  2. 2Have the prescriber submit a supporting statement with clinical rationale
  3. 3Document all failed alternatives with dates, doses, and outcomes
  4. 4For Medicare Part D, use the CMS standardized exception process — the plan must decide within 72 hours standard / 24 hours expedited, counted from the prescriber's supporting statement (42 CFR 423.568(b), 423.572(a))
  5. 5Check if the state has any PBM transparency or gag clause prohibition laws

Points to Check

  • Step therapy protocols can be overridden with proper documentation of medical necessity
  • State PBM reform laws may provide additional protections (e.g., gag clause prohibitions)
  • Medicare Part D has strict CMS-mandated exception timelines that CVS Caremark must follow
