What Affects Approval Timeline

Several factors determine how quickly Blue Cross Blue Shield of Michigan processes your Thiola/Thiola EC prior authorization:

Benefit Type: Thiola is typically covered under the pharmacy benefit as a non-preferred specialty drug (Tier 4 or higher), requiring prior authorization and potentially step therapy requirements.

Documentation Completeness: The most common cause of delays is incomplete clinical documentation. BCBS Michigan requires specific evidence including:

  • Confirmed cystinuria diagnosis (ICD-10: E72.01)
  • 24-hour urine cystine levels >500 mg/day
  • Documentation of failed conservative therapy
  • Specialist prescription from urologist or nephrologist

Specialty Review: Since Thiola is a specialty medication for a rare condition, requests may require additional clinical review, which can extend processing time.

Note: Blue Cross Blue Shield of Michigan covers approximately 67% of commercial plan members in the state, making their policies particularly important for Michigan patients.
