Common Denial Reasons & How to Fix Them

Denial Reason Documentation to Overturn Action Steps
"Experimental/Investigational" FDA approval letter, prescribing information Submit FDA approval documentation dated August 2024 for Kebilidi (US brand)
"Non-formulary" Medical necessity letter, formulary exception request Request formulary exception with clinical justification
"Unconfirmed diagnosis" Genetic testing results, enzyme activity levels Provide comprehensive DDC gene analysis and biochemical confirmation
"Inappropriate setting" Center certification, surgeon credentials Document facility meets FDA stereotactic surgery requirements
"Lack of medical necessity" Clinical notes, severity documentation, failed therapies Detail severe phenotype, developmental delays, medication failures
From Our Advocates: We've seen AADC deficiency denials overturned when families provided comprehensive genetic testing alongside detailed documentation of the child's severe motor delays and failed medication trials. The key is demonstrating both the confirmed diagnosis and the severity that meets FDA-approved indications.

Clinician Corner: Medical Necessity Requirements

Essential Documentation for PA Success

Medical Necessity Letter Must Include:

  • Confirmed AADC deficiency diagnosis with specific genetic mutations
  • Clinical presentation consistent with severe phenotype (developmental delays, oculogyric crises, autonomic dysfunction)
  • Documentation of failed or inadequate response to standard therapies
  • Patient meets FDA age requirement (≥18 months)
  • Treatment center meets specialized facility requirements
  • Expected clinical benefits and monitoring plan

Key Clinical Evidence:

  • Genetic testing: DDC gene mutations via MLPA or next-generation sequencing
  • Biochemical markers: Elevated 3-OMD levels, reduced AADC activity
  • Clinical assessments: Motor development scales, seizure frequency, quality of life measures
  • Prior treatment history: Dopamine agonists, MAO inhibitors, other supportive care

Monitoring and Follow-up Documentation

Recent research shows that clinical observation is more valuable than CSF biomarker monitoring for assessing Upstaza response. Focus documentation on:

  • Motor milestone achievements
  • Reduction in oculogyric crises
  • Improved autonomic function
  • Enhanced quality of life measures
