Prior Therapies Evidence of treatment failures Complete treatment history with dates and outcomes

Common Denial Reasons & How to Fix Them

Denial Reason Fix Strategy Required Documentation
IDH1 mutation not documented Submit FDA-approved test results Lab report with specific mutation subtype identified
Insufficient prior therapy Document treatment failures/intolerance Complete treatment timeline with outcomes and side effects
Non-oncology prescriber Transfer to hematologist/oncologist Board-certified specialist's prescription and evaluation
Missing monitoring plan Provide detailed safety protocol Plan for differentiation syndrome monitoring and liver function tests
Not medically necessary Strengthen clinical rationale Updated medical necessity letter with guideline citations
From Our Advocates: We've seen cases where initial denials were overturned simply by providing more detailed documentation of prior therapy failures. One patient's approval came after submitting specific dates, doses, and documented side effects from previous treatments. The key was showing why alternatives weren't viable options.

  7. FDA indication reference and relevant clinical guidelines (NCCN, ASH)

Sample Key Statement

"It is my medical opinion that Rezlidhia (olutasidenib) is medically necessary for this patient with relapsed/refractory AML harboring an IDH1 R132 mutation. Previous standard therapies have failed, and this FDA-approved targeted therapy represents the most appropriate treatment option based on the tumor's molecular profile and current clinical guidelines."
