How to appeal a Step Therapy / Fail-First denial
A step-therapy or fail-first denial means the payer won't cover the drug or treatment you ordered until the patient has tried and failed a cheaper preferred option first, even when the clinical case for going straight to your choice is strong.
Common code: CARC 197 (precert/auth absent) / 243 (services not authorized by network provider) — step-therapy protocol not metWhy payers issue it
- The payer's formulary requires a preferred agent be tried before yours
- The patient's prior failures or contraindications weren't documented on the request
- An exception was warranted but never filed
- The protocol applies but the patient already met it and it wasn't shown
What overturns it
- Document the patient's prior trials, failures, intolerances, or contraindications to the preferred agent
- File a step-therapy exception or medical-necessity override with the clinical record
- Cite the payer's own exception criteria and any state step-therapy override law
- Request a peer-to-peer to make the case directly to the medical director
Worth appealing? Step-therapy denials hit biologic-heavy specialties hardest, and they're frequently overturned once the chart shows the patient already failed or can't take the preferred drug. The clinical justification usually exists, it just has to reach the reviewer.

A step-therapy or fail-first denial means the payer won't cover the drug or treatment you ordered until the patient has tried and failed a cheaper preferred option first, even when the clinical case for going straight to your choice is strong. To overturn it: document the patient's prior trials, failures, intolerances, or contraindications to the preferred agent; file a step-therapy exception or medical-necessity override with the clinical record; cite the payer's own exception criteria and any state step-therapy override law; request a peer-to-peer to make the case directly to the medical director.
