Understanding Your Denial Letter

When Aetna denies Arcalyst coverage, the denial letter will specify the reason code. Common reasons include:

  • Prior authorization required (most common for new requests)
  • Step therapy not met (for recurrent pericarditis - must try colchicine and NSAIDs first)
  • Non-formulary drug (Arcalyst may require formulary exception)
  • Diagnosis not covered (must be FDA-approved indication: CAPS, DIRA, or recurrent pericarditis)
  • Prescriber requirements not met (must be cardiologist or rheumatologist)
Tip: Look for the appeal deadline in your denial letter. Texas law gives you up to 4 years to appeal, but acting quickly improves your chances.
