Specialty pharmacy won't fill my script — what do I do?
Specialty pharmacy refusal usually means a prior-auth or formulary issue. Diagnose then fight.
When a specialty pharmacy (Accredo, CVS Specialty, Optum Specialty, etc.) refuses to fill your prescription, the root cause is almost always at the PBM or plan level — prior-auth missing, formulary exclusion, step-therapy requirement, or quantity limit. The pharmacy is just the messenger.
Steps
- Call the specialty pharmacy and ask for the SPECIFIC reason for refusal (CARC code or PBM rejection reason)
- Identify whether it's prior auth, formulary, step therapy, or quantity
- Have the prescriber's office submit the appropriate paperwork (PA form, formulary exception, peer-to-peer)
- If still denied, formal appeal through the plan's process
