How to Get Zokinvy (Lonafarnib) Covered by Blue Shield of California: PA Requirements, Appeals & Success Strategies

Answer Box: Your Fastest Path to Zokinvy Coverage

Blue Shield of California covers Zokinvy (lonafarnib) as a specialty drug requiring prior authorization. You need confirmed HGPS or progeroid laminopathy diagnosis via genetic testing, patient age ≥12 months, BSA ≥0.39 m², and dispensing through their network specialty pharmacy like CVS Specialty.

Three steps to start today:

  1. Contact the Progeria Research Foundation for free genetic testing if not done
  2. Have your prescriber submit PA via Blue Shield provider portal with genetic confirmation
  3. Set up specialty pharmacy delivery through Blue Shield's network

California's Independent Medical Review overturns 55-75% of Blue Shield denials when properly documented.

Plan Types & Network Requirements

Blue Shield of California operates differently than other Blue Cross Blue Shield plans nationwide. As an independent licensee, they have their own formularies and policies across their plan types:

Commercial Plans (Standard, Plus, Value, Performance)

  • HMO plans require referrals to specialists; PPO plans allow direct access
  • All plan types include Zokinvy on their specialty drug formularies
  • Network requirements apply regardless of plan type

Blue Shield Promise (Medi-Cal)

  • Covers Zokinvy under Medicaid specialty drug benefits
  • Same PA requirements as commercial plans
  • Additional state oversight through California Department of Health Care Services
Note: Blue Shield of California is distinct from Anthem Blue Cross California. Make sure you're working with the correct insurer by checking your member ID card.

Formulary Status & Tier Placement

Zokinvy appears on all Blue Shield of California specialty drug lists for 2024:

Coverage Requirements:

  • Must be specified in your Evidence of Coverage (EOC)
  • Prior authorization required for all plan types
  • No preferred alternatives listed (Zokinvy is the only FDA-approved treatment for HGPS)

The drug's inclusion across all formularies reflects its orphan drug status and lack of therapeutic alternatives for progeria patients.

Prior Authorization Requirements

Medical Necessity Criteria

Based on Blue Shield's PA policies, Zokinvy approval requires:

Requirement Details Documentation Needed
Age ≥12 months Birth certificate or medical records
Body Surface Area ≥0.39 m² (Mosteller formula) Height/weight measurements
Genetic Confirmation Pathogenic LMNA mutation CLIA-certified genetic test report
Diagnosis HGPS or processing-deficient progeroid laminopathies ICD-10 Q87.1, specialist evaluation

Genetic Testing Requirements

The Progeria Research Foundation offers free diagnostic testing:

  • Submit clinical history to PRF medical director

Common pathogenic variants include:

  • c.1824C>T (G608G) - most frequent
  • Other documented LMNA mutations per policy appendix
Important: Direct-to-consumer tests like 23andMe are not acceptable for PA approval. You need clinical-grade genetic testing.

Specialty Pharmacy Setup

Blue Shield requires Zokinvy dispensing through their network specialty pharmacies.

Primary Network Partner:

  • CVS Specialty: 800-237-2767 (fax: 800-323-2445)

Setup Process:

  1. Verify Coverage: Check your member portal or call the number on your ID card
  2. PA Approval: Must be completed before pharmacy setup
  3. Prescription Transfer: Your prescriber faxes to CVS Specialty after PA approval
  4. Delivery Coordination: CVS contacts you for scheduling and insurance verification

Manufacturer Support: Sentynl Cares (1-888-251-2800) provides:

  • Bridge therapy during insurance processing
  • Financial assistance program information
  • Prescription transfer coordination

If Zokinvy isn't available through network pharmacies (rare), Blue Shield allows non-network specialty pharmacy dispensing with prior approval.

From Our Advocates: We've seen the strongest approvals when genetic testing clearly documents a pathogenic LMNA variant and the prescriber includes a detailed letter explaining how Zokinvy addresses the patient's specific progeria manifestations. Complete documentation upfront prevents delays and reduces the need for appeals.

Common Denial Reasons & Fixes
