How to Use This Guide

This guide helps patients and families navigate Humana's coverage requirements for Upstaza (eladocagene exuparvovec), the FDA-approved gene therapy for AADC deficiency. We'll walk through eligibility requirements, documentation needs, and New York's appeal options if coverage is initially denied.

  • Age 18 months or older
  • Access to a certified gene therapy center in New York
  • Documented severe motor dysfunction consistent with AADC deficiency

⚠️ Possibly Eligible if you have SOME of these:

  • Clinical symptoms suggesting AADC deficiency but incomplete testing

  • Supportive care measures for motor symptoms
  • Physical and occupational therapy
  • Nutritional support and feeding assistance

Preparing for Exception Requests

If standard criteria aren't met, you may still qualify through Humana's medical exception process. This requires:

If Your Coverage Is Denied

New York residents have strong appeal rights when insurance denies coverage for medical treatments.

Internal Appeal (First Step)

  • Additional supporting documentation
  • Revised medical necessity letter

Peer-to-Peer Review

Request a discussion between your prescribing physician and Humana's medical reviewer. This often resolves coverage disputes before formal appeals.

Key benefits of New York's external appeal:

  • Independent medical expert review
  • Binding decision on the insurance company
  • Expedited review available (72 hours for urgent cases)
  • Maximum $25 filing fee (waived for financial hardship)
