Appealing a Cosentyx denial by insurer
The path depends on who manages your benefit. The most common:
Coverage runs through the pharmacy benefit. Appeal the coverage determination and, when the drug is non-formulary, file a formulary or tier exception with a provider attestation that covered alternatives are unsuitable.
Publishes detailed prior-authorization criteria. A denial usually means a criterion was not documented. Appeal through a coverage review, with a formulary exception for excluded drugs.
Administers many UnitedHealthcare and employer plans. Appeals and exceptions follow the plan's published PA criteria; expedited review exists for urgent cases.
Internal appeal first, then independent external review. Pre-service decisions are generally made within 30 days, urgent within 72 hours.
Internal appeals and external review; pharmacy denials often route through OptumRx criteria.
Independent state plans, so criteria vary. Match the appeal to your specific BCBS plan, internal appeal first, then external review.
