Prior Authorization Requirements

Humana requires prior authorization for Upstaza as a specialty gene therapy. The request must include:

Clinical Documentation:

  • Confirmed AADC deficiency with genetic testing showing biallelic DDC mutations
  • CSF neurotransmitter analysis demonstrating low HVA and 5-HIAA levels
  • Plasma AADC activity <0.22 pmol/min/mL (if available)
  • Current motor function assessment using validated scales

Treatment History:

  • Documentation of supportive care measures tried
  • Response to current medications (MAO inhibitors, dopamine agonists)
  • Frequency and severity of oculogyric crises and other symptoms

Center Certification:

  • Confirmation that the treating facility has pediatric stereotactic neurosurgery capabilities
  • Documentation of experience with gene therapy administration
  • Post-operative monitoring plan for 14-day inpatient period
Tip: Submit requests electronically through Humana's provider portal when possible. Electronic submissions receive decisions within 1 business day for 95% of complete requests, compared to up to 7 days for other methods.

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documentation
Insufficient genetic confirmation Provide comprehensive genetic testing Biallelic DDC mutations from certified lab
Lack of center certification Verify facility credentials Hospital documentation of stereotactic capabilities
Missing prior treatment documentation Submit complete treatment history Records of supportive care and medication trials
Age eligibility questions Confirm patient age and skull maturity Birth certificate and neurosurgical assessment
Medical necessity unclear Strengthen clinical rationale Motor milestone data and quality of life measures

Most Effective Appeal Strategy: Focus on the lack of alternative treatments. Unlike other conditions, AADC deficiency has no curative therapies besides gene therapy, making medical necessity arguments particularly strong.

Frequently Asked Questions

How long does Humana prior authorization take for gene therapy? Standard requests receive decisions within 7 calendar days, with 95% of electronic submissions decided within 1 business day when complete. Expedited requests are processed within 72 hours when medical urgency is demonstrated.

What if Upstaza is not on Humana's formulary? Gene therapies may require formulary exceptions. Submit a tier exception request with medical necessity documentation. Non-formulary drugs can still be covered when medically necessary and no formulary alternatives are appropriate.

Can I request an expedited appeal if my child's condition is worsening? Yes. Washington allows expedited external review within 72 hours when standard timelines would seriously jeopardize health. Document medical urgency with physician statements about deteriorating function.

Does step therapy apply to gene therapy? Step therapy requirements vary by plan, but for AADC deficiency, there are no alternative gene therapies to try first. Focus on documenting that supportive care measures have been maximized.

What happens if I miss an appeal deadline? Contact Humana immediately to request an extension. Washington law may provide additional protections if you can demonstrate good cause for the delay, such as serious illness or lack of proper notice.

How do I find a certified treatment center in Washington? Contact the manufacturer at PTCcares.com for a list of certified centers. Major academic medical centers with pediatric neurosurgery programs are most likely to have the required capabilities.
