The fastest path to approval involves three key steps: 1) Ensure your prescriber submits complete clinical documentation including diagnosis (ICD-10 code M04.2 for CAPS, I30.1 for recurrent pericarditis), prior therapy failures, and medical necessity justification; 2) Use correct billing codes (HCPCS J2793, NDC 73604-0914-xx) and meet step therapy requirements; 3) If denied, appeal within 180 days using Texas's strong patient protection laws. Start today by calling the number on your BCBSTX ID card to confirm current PA requirements and submission methods.

Coding Basics: Medical vs. Pharmacy Benefit Paths

Arcalyst (rilonacept) typically falls under the medical benefit for Blue Cross Blue Shield of Texas, not the pharmacy benefit. This means it's processed like an injectable medication administered in a clinical setting, even though patients self-inject at home.

Key Distinctions:

  • Medical Benefit: Uses HCPCS J-codes, requires prior authorization through medical management
  • Pharmacy Benefit: Uses NDC codes, processed through pharmacy benefits manager
  • BCBSTX Classification: Medical benefit for all FDA-approved indications
Tip: Always verify benefit classification by calling the member services number on your BCBSTX ID card, as some employer plans may have different structures.

ICD-10 Mapping for Arcalyst Coverage

Proper diagnosis coding is critical for Arcalyst approval. BCBSTX requires documentation that matches FDA-approved indications exactly.

Primary ICD-10 Codes for Arcalyst

Condition ICD-10 Code Documentation Requirements
CAPS (FCAS, MWS) M04.2 Cryopyrin-associated periodic syndromes with clinical features
DIRA E88.89 or E88.0 Genetic confirmation (IL1RN mutation) preferred
Recurrent Pericarditis I30.1 or I30.8 ≥2 documented episodes with inflammatory markers

Supporting Documentation Language

When documenting for prior authorization, use specific terminology that aligns with BCBSTX medical policies:

  • For CAPS: "Recurrent fever episodes," "cold-induced urticaria," "progressive sensorineural hearing loss" (MWS)
  • For DIRA: "Severe systemic inflammation," "pustular skin lesions," "IL1RN gene mutation confirmed"
  • For Recurrent Pericarditis: "Elevated CRP/ESR during episodes," "chest pain with pericardial friction rub," "recurrent after initial episode resolution"
