Work With Your Doctor to Get Upstaza (Kebilidi) Covered by Aetna in Pennsylvania: Complete Provider Partnership Guide

Answer Box: Getting Aetna to Cover Upstaza (Kebilidi) in Pennsylvania

Upstaza (Kebilidi) requires prior authorization from Aetna with genetic confirmation of AADC deficiency, treatment at a designated center, and comprehensive medical documentation. Your doctor must submit genetic testing results, enzyme assays, and clinical notes showing failed standard therapies. If denied, Pennsylvania's external review program overturns ~50% of appeals. Start today: Call Aetna at 1-866-752-7021 to request Kebilidi coverage criteria, then schedule a visit with your neurologist/geneticist to review diagnostic requirements and prepare your medical necessity letter.

Set Your Goal: What Approval Requires

Understanding Aetna's Kebilidi Coverage Criteria

Aetna treats Kebilidi (eladocagene exuparvovec-tneq) as a high-cost gene therapy requiring strict prior authorization. Based on Aetna's Clinical Policy Bulletin, your approval will depend on meeting these core requirements:

Diagnostic Confirmation Requirements:

  • Genetic testing showing biallelic pathogenic DDC variants
  • Biochemical evidence from at least one core test:
    • Plasma AADC enzyme activity (reduced)
    • CSF neurotransmitter metabolite panel (characteristic pattern)
  • Clinical phenotype consistent with classic AADC deficiency

Treatment Setting Requirements:

  • Therapy at a designated treatment center (currently Boston Children's Hospital or Texas Children's Hospital)
  • Prescribed by pediatric neurologist or geneticist
  • Single lifetime dose only

Your Partnership Strategy

Success requires coordinating with multiple specialists:

  1. Primary neurologist/geneticist (writes medical necessity letter)
  2. Designated Kebilidi center (confirms treatment capability)
  3. Aetna specialist (manages prior authorization)
Note: Currently, no Pennsylvania treatment centers are publicly listed. Patients typically travel to Boston Children's Hospital or Texas Children's Hospital for treatment.

Visit Preparation: Documenting Your Journey

Before Your Appointment

Create a comprehensive symptom and treatment timeline to support your case:

Symptom Documentation Checklist:

  • Motor milestones: When did delays become apparent? (sitting, standing, walking)
  • Movement symptoms: Frequency and severity of oculogyric crises, dystonia
  • Autonomic symptoms: Temperature instability, feeding difficulties, hypotension
  • Developmental impact: Communication, cognitive milestones, daily functioning

Treatment History Summary:

  • Medications tried: Dopamine agonists (levodopa/carbidopa), MAO-B inhibitors
  • Duration and dosing for each medication

  • Reasons for discontinuation: Intolerance, ineffectiveness, contraindications

Questions to Prepare for Your Doctor

  1. "Do my diagnostic tests meet Aetna's requirements for Kebilidi coverage?"
  2. "Which designated treatment center would you recommend for our family?"
  3. "Can you help prepare a medical necessity letter addressing Aetna's specific criteria?"
  4. "What additional documentation might strengthen our prior authorization?"

FAQ: Common Questions

How long does Aetna prior authorization take for Kebilidi in Pennsylvania? Standard review is typically 30-45 days, with expedited reviews possible for urgent cases within 72 hours for Medicare members.

What if Kebilidi is non-formulary on my Aetna plan? Request a formulary exception with documentation of medical necessity and lack of formulary alternatives. CVS Caremark manages most Aetna specialty drug authorizations.

Can I request expedited appeal if treatment is delayed? Yes, if delays could seriously jeopardize health or ability to regain function. Provide physician documentation of urgency.

Does step therapy apply to Kebilidi? Typically yes - Aetna requires documentation of failed or inappropriate standard AADC deficiency treatments before approving gene therapy.

What if my employer plan is self-funded? Self-funded ERISA plans may not be eligible for Pennsylvania's external review program. Contact your plan administrator for specific appeal procedures.

How much does Kebilidi cost without insurance? Published analyses report multimillion-dollar pricing typical of one-time gene therapies, making insurance coverage essential for most families.
