Understanding Your Denial Letter

When Cigna denies coverage for Rezlidhia (olutasidenib), the first step is decoding your denial letter. Look for these key elements:

  • Reason code: Common codes include "not medically necessary," "step therapy required," or "non-formulary drug"
  • Appeal deadline: Typically 180 calendar days from the denial date
  • Required documentation: What Cigna needs to reconsider the decision
  • Contact information: Phone numbers for member services and appeals
Tip: Keep your denial letter handy—you'll reference it throughout the appeal process.

Most Rezlidhia denials occur when IDH1 mutation testing isn't properly documented or when prior therapy failures aren't clearly established in your medical record.
