Policy Overview

UnitedHealthcare covers Upstaza (marketed as Kebilidi in the US) under their medical benefit drug policy rather than standard pharmacy benefits. The therapy requires prior authorization across all plan types—commercial HMO/PPO, Medicare Advantage, and Medicaid managed care plans in Michigan.

Plan Types and Coverage

  • Fully-insured commercial plans: Eligible for Michigan external review if denied
  • Self-funded employer plans: Follow internal appeals only; cannot use state external review
  • Medicare Advantage: Subject to CMS appeal rights and expedited review options
  • Medicaid managed care: Coverage through Michigan's Medicaid program with state-specific appeal processes
Note: Check your member ID card to determine if OptumRx manages your pharmacy benefits, as this affects the prior authorization submission process.

The official policy documents can be found on the UnitedHealthcare Provider Portal, though gene therapy policies are often managed separately from standard formulary listings.


Medical Necessity Requirements

UnitedHealthcare's coverage criteria for Upstaza align with FDA labeling and clinical guidelines. All of the following must be documented:

Diagnostic Confirmation

Genetic Testing Requirements:

  • Biallelic pathogenic variants in the DDC gene confirmed through genetic sequencing
  • Laboratory report showing compound heterozygous or homozygous mutations
  • Testing performed at a CLIA-certified laboratory

Clinical Presentation:

  • Documented autonomic dysfunction consistent with AADC deficiency
  • Developmental delays and neurological symptoms
  • Patient age ≥18 months (per FDA approval)

Biochemical Evidence (at least one required):

  • Plasma AADC enzyme activity assay showing decreased or absent activity, OR
  • CSF neurotransmitter metabolites showing characteristic pattern (low 5-HIAA, low HVA, elevated 3-OMD, elevated L-dopa)

Treatment Setting Requirements

  • Therapy must be administered at a UnitedHealthcare-certified gene therapy center
  • Verify network status and certification before scheduling
  • Centers must have specialized neurosurgical capabilities for stereotactic infusion

Non-certified treatment center Switch to certified facility UnitedHealthcare provider directory verification
Incomplete clinical documentation Comprehensive symptom assessment Detailed neurological evaluations, developmental assessments
Age eligibility question Confirm patient ≥18 months Birth certificate, current age documentation

Frequently Asked Questions

How long does UnitedHealthcare prior authorization take in Michigan? Standard prior authorization decisions are made within 15 business days. Expedited reviews (when medically urgent) are completed within 72 hours. Call 1-800-711-4555 to request expedited review.

What if Upstaza is not on my formulary? Upstaza/Kebilidi is covered under medical benefit policies rather than standard pharmacy formularies. Prior authorization is required regardless of formulary status.

Can I request an expedited appeal if denied? Yes, if your physician certifies that delay would seriously jeopardize your health. Both UnitedHealthcare internal appeals and Michigan external reviews offer expedited timelines (72 hours).

Does step therapy apply to gene therapies? While no direct alternatives exist for AADC deficiency gene therapy, UnitedHealthcare may require documentation of supportive care attempts and symptom progression.

What happens if my employer plan is self-funded? Self-funded plans cannot use Michigan's external review process. You must follow the plan's internal appeal procedures and may have access to federal external review options.

How do I find a UnitedHealthcare-certified gene therapy center? Call UnitedHealthcare provider services at 1-800-711-4555 to verify certified centers in your area. Not all facilities offering gene therapy are necessarily certified by UnitedHealthcare.

What documentation should I keep during the appeals process? Maintain copies of all submissions, confirmation numbers, correspondence, and medical records. Document all phone calls with dates, times, and representative names.

Can my doctor help with the appeal process? Yes, physicians can file appeals on your behalf with proper authorization. Many successful appeals include physician peer-to-peer reviews with UnitedHealthcare medical directors.


From our advocates: We've seen families successfully navigate gene therapy approvals by starting the documentation process early—often months before the planned treatment date. The key is having all genetic testing, clinical assessments, and center certifications confirmed before submitting the initial prior authorization. While each case is unique, thorough preparation significantly improves approval chances.
