Non-formulary drug denials
Your drug isn't on the plan's formulary. Appealable via the plan's formulary exception process — which federal law requires plans to maintain.
What this denial means
A non-formulary denial means the requested drug is not on the plan's formulary (preferred drug list) at all, or is on a tier with prohibitive cost-sharing. Federal law requires all ACA-compliant plans, Medicare Part D plans, and most commercial plans to maintain a formulary exception process — a way for you to request coverage of a non-formulary drug when it's medically necessary.
How to appeal it
Formulary exception requests typically require the prescriber to document: (1) why the formulary alternatives are clinically inappropriate (allergy, intolerance, contraindication, prior failure, or inferior efficacy); (2) the specific clinical evidence supporting the requested non-formulary drug for the patient's condition; (3) the prescribed dosing and duration. For Medicare Part D, formulary exception decisions: 24 hours expedited / 72 hours standard. For commercial plans: 72 hours expedited / 7 days standard (varies). When denied, escalate to internal appeal then external review.
