UnitedHealthcare's Coverage Criteria for Zokinvy (lonafarnib) in Georgia: What Counts as "Medically Necessary"?

Answer Box: Getting Zokinvy Covered by UnitedHealthcare in Georgia

Zokinvy (lonafarnib) requires prior authorization from UnitedHealthcare with strict genetic and clinical criteria. To qualify, you need documented HGPS or specific progeroid laminopathy mutations, age ≥12 months, BSA ≥0.39 m², and specialist prescription. First step today: Contact your genetics specialist to confirm genetic testing results and initiate the prior authorization through OptumRx. If denied, Georgia offers external review within 60 days through the Georgia Department of Insurance.

Policy Overview: Plan Types and Coverage

UnitedHealthcare requires prior authorization for Zokinvy across all plan types—HMO, PPO, and Medicare Advantage—through their pharmacy benefits manager OptumRx. The medication carries a PA (Prior Authorization) flag on all UnitedHealthcare formularies, meaning coverage is never automatic.

Coverage at a Glance

Requirement What It Means Where to Find It
Prior Authorization Required for all plans UHC PA Notification
Formulary Status PA flag on all tiers OptumRx formulary documents
Authorization Duration 12 months initial and renewal UHC policy documents
Age Requirement ≥12 months FDA labeling requirements
BSA Requirement ≥0.39 m² Clinical dosing criteria

Indication Requirements: FDA Status and Genetic Confirmation

Zokinvy has FDA approval for two specific conditions, and UnitedHealthcare strictly adheres to these indications:

Covered Diagnoses

  • Hutchinson-Gilford Progeria Syndrome (HGPS) with documented LMNA gene mutation
  • Processing-deficient Progeroid Laminopathies with either:
    • Heterozygous LMNA mutation with progerin-like protein accumulation, or
    • Homozygous/compound heterozygous ZMPSTE24 mutations

Genetic Testing Requirements

All approvals require CLIA-certified laboratory results confirming the specific genetic mutation. The Progeria Research Foundation offers diagnostic testing programs that may provide testing at no cost to families.

Note: Processing-proficient progeroid laminopathies and other progeroid syndromes are explicitly excluded from coverage.

Step Therapy and Medical Exceptions

UnitedHealthcare does not list specific step therapy protocols for Zokinvy in their June 2025 policy, likely because no therapeutic alternatives exist for these ultra-rare conditions.

However, some automated systems may flag the request for step therapy review. If this occurs:

  1. Document lack of alternatives in the medical necessity letter
  2. Reference FDA orphan drug status and unique mechanism of action
  3. Cite clinical guidelines showing Zokinvy as first-line therapy

Quantity Limits and Dosing Rules

  • Initial 4 months: 115 mg/m² twice daily with food

BSA Calculation Requirements

UnitedHealthcare requires current height and weight documentation to verify BSA ≥0.39 m². Dosing must not exceed FDA label specifications, with member measurements provided to the insurance plan.

Example BSA Calculation:

  • 2-year-old, 12 kg, 85 cm = BSA 0.53 m² (qualifies)
  • Daily dose: 115 mg/m² × 0.53 m² = 61 mg twice daily

Required Diagnostics and Documentation

Essential Documentation Checklist

  • Genetic test results from CLIA-certified laboratory
  • Specialist consultation notes confirming diagnosis
  • Current height and weight with BSA calculation
  • Cardiovascular monitoring plan (carotid ultrasound or PWV)
  • ICD-10 code Q87.1 (congenital malformation syndromes)
  • HCPCS J-code J8499 for billing

Specialist Requirements

Prescription must come from or be made in consultation with:

  • Geneticist
  • Metabolic disorder specialist
  • Progeria specialist
  • Pediatrician with genetics expertise

Specialty Pharmacy Requirements

UnitedHealthcare typically routes Zokinvy through their specialty pharmacy network via OptumRx. While specific site-of-care restrictions for Georgia weren't available in our research, most specialty medications require:

  • Specialty pharmacy dispensing (not retail pharmacy)
  • Prior authorization approval before first fill
  • Temperature-controlled shipping for oral capsules
  • Patient education and monitoring through pharmacy services

Contact OptumRx at 888-397-8129 to verify current network requirements and preferred dispensing locations in Georgia.

Sample Medical Necessity Letter

Key Elements to Include:

"[Patient name] is a [age]-year-old with genetically confirmed [HGPS/progeroid laminopathy] requiring Zokinvy (lonafarnib) therapy. Genetic testing from [CLIA lab] confirms [specific mutation]. Current BSA is [X.XX] m², meeting FDA criteria of ≥0.39 m².

Zokinvy is FDA-approved specifically for reducing mortality risk in this condition, with no therapeutic alternatives available. The progressive nature of [condition] necessitates immediate treatment initiation. Cardiovascular monitoring will be conducted via [carotid ultrasound/PWV] every [frequency].

Dosing will follow FDA labeling: [dose] mg/m² twice daily with food, with planned increase after 4 months per protocol."

Common Denial Reasons and Solutions

Denial Reason Solution Required Documents
Missing genetic confirmation Submit CLIA lab results Genetic test report
Insufficient BSA Provide current measurements Height/weight documentation
Non-specialist prescriber Add genetics consultation Specialist attestation
Dosing concerns Clarify BSA-based calculation Dosing worksheet
Lack of monitoring plan Detail cardiovascular surveillance Monitoring protocol
