UnitedHealthcare's Coverage Criteria for Upstaza (Eladocagene Exuparvovec) in Washington: What Counts as "Medically Necessary"?

Answer Box: UnitedHealthcare requires prior authorization for Upstaza (eladocagene exuparvovec) gene therapy, demanding genetic confirmation of DDC mutations, biochemical proof of AADC deficiency, and administration at a certified gene therapy center. If denied, Washington residents can appeal through internal review, then request external review through an Independent Review Organization (IRO). First step: Gather genetic testing results, enzyme activity assays, and clinical documentation before submitting the OptumRx prior authorization form.

Policy Overview

UnitedHealthcare manages Upstaza (eladocagene exuparvovec) coverage through OptumRx, their specialty pharmacy benefit manager. The therapy requires prior authorization across all plan types—commercial HMO/PPO, Medicare Advantage, and Medicaid managed care plans in Washington.

Key Policy Elements:

  • Prior Authorization: Required for all Upstaza/Kebilidi requests
  • Formulary Status: Typically non-formulary or specialty tier requiring extensive documentation
  • Plan Coverage: Fully-insured commercial plans eligible for Washington's external review; self-funded ERISA plans have limited state appeal rights
  • Administration Route: Medical benefit coverage for inpatient gene therapy administration

Medical Necessity Requirements

UnitedHealthcare's medical necessity criteria for Upstaza align with FDA labeling and established diagnostic standards for AADC deficiency:

Core Requirements

Requirement Documentation Needed Source
Genetic Confirmation Biallelic pathogenic mutations in DDC gene FDA Label
Age Eligibility Patient ≥18 months old FDA Labeling
Clinical Diagnosis Documented AADC deficiency symptoms Clinical assessment
Biochemical Evidence Reduced plasma AADC enzyme activity OR characteristic CSF neurotransmitter profile Laboratory confirmation
Treatment Setting Certified gene therapy center with qualified neurosurgical team UHC Policy

Clinical Presentation Documentation

Your medical necessity letter must document classic AADC deficiency symptoms:

  • Severe developmental delays and hypotonia
  • Oculogyric crises and movement disorders
  • Autonomic dysfunction (temperature instability, excessive sweating)
  • Feeding difficulties and failure to thrive
Tip: Include specific developmental milestone delays with dates and assessments to strengthen your case.

Step Therapy & Exception Pathways

While no direct alternatives exist for AADC deficiency gene therapy, UnitedHealthcare typically requires documentation of:

Previous Treatment Attempts:

  1. Supportive medications (dopamine agonists, MAO inhibitors, vitamin B6/pyridoxine)
  2. Symptomatic management (anti-seizure medications, feeding support)
  3. Physical and occupational therapy interventions

Medical Exception Criteria:

  • Contraindications to standard supportive care
  • Documented treatment failures with conventional approaches
  • Progressive disease despite optimal supportive management

Submit exception requests through the OptumRx prior authorization portal with detailed clinical rationale.

Required Diagnostics

Essential Laboratory Evidence

UnitedHealthcare requires at least two independent diagnostic modalities for coverage approval:

Primary Tests:

  • Genetic Testing: DDC gene sequencing showing biallelic pathogenic variants
  • Enzyme Activity: Plasma AADC enzyme assay demonstrating reduced activity (<50% of normal)

Supporting Evidence:

  • CSF Analysis: Neurotransmitter metabolite panel showing:
    • Low 5-hydroxyindoleacetic acid (5-HIAA)
    • Low homovanillic acid (HVA)
    • Elevated 3-O-methyldopa (3-OMD)
    • Elevated L-DOPA

Documentation Requirements

All test results must be:

  • From CLIA-certified laboratories
  • Performed within 12 months of PA submission
  • Include reference ranges and interpretation
  • Signed by ordering physician
Note: Some plans may accept older genetic testing if the diagnosis is well-established, but recent biochemical confirmation is typically required.

Site of Care Requirements

UnitedHealthcare mandates Upstaza administration at designated Centers of Excellence (COE) meeting specific criteria:

Facility Requirements:

  • UnitedHealthcare/Optum-recognized gene therapy center
  • Specialized neurosurgical team experienced in stereotactic procedures
  • Inpatient monitoring capabilities for post-procedure care
  • Compliance with FDA REMS program requirements

Provider Qualifications:

  • Board-certified neurosurgeon with gene therapy experience
  • Multidisciplinary team including anesthesiology, intensive care
  • Institution must maintain gene therapy accreditation

Evidence Documentation

Clinical Guidelines to Reference

When building your medical necessity case, cite these authoritative sources:

  1. FDA Labeling: Kebilidi prescribing information and clinical trial data
  2. International Guidelines: European consensus on AADC deficiency diagnosis and management
  3. Peer-Reviewed Literature: Published case series and outcome studies
  4. Professional Society Statements: Child Neurology Society or similar endorsements

Sample Medical Necessity Narrative

"Patient meets FDA-approved indication for eladocagene exuparvovec with confirmed biallelic DDC mutations (c.XXX>X, c.XXX>X), plasma AADC enzyme activity <10% of normal, and classic phenotype including developmental delays, oculogyric crises, and autonomic dysfunction. Previous trials of pyridoxine, carbidopa/levodopa, and dopamine agonists provided minimal benefit. Gene therapy represents the only disease-modifying treatment option for this progressive, life-limiting condition."

Appeals Process in Washington

Washington state provides robust consumer protections for insurance denials, including gene therapy coverage disputes.

Internal Appeals Process
