Policy Overview: Blue Cross Blue Shield California Plans

Blue Shield of California operates as an independent Blue Cross Blue Shield Association plan, covering both commercial and Medicaid (Medi-Cal) members across the state. Their Brineura coverage policy applies to all plan types but may have different prior authorization workflows.

Key Policy Details:

  • Prior authorization required for all Brineura prescriptions
  • Specialty tier placement with higher cost-sharing
  • Site-of-care restrictions to specialized infusion centers
  • Ongoing authorization required for continued treatment

The policy follows FDA labeling closely but adds specific documentation requirements for coverage determination.

Indication Requirements: CLN2 Disease Confirmation

Diagnostic Criteria

Blue Shield California requires confirmed CLN2 disease diagnosis through one of two methods:

  1. TPP1 enzyme deficiency demonstrated in leukocytes, fibroblasts, or dried blood spots
  2. Two pathogenic variants in the TPP1/CLN2 gene (biallelic mutations in trans)

The diagnosis must be established by a geneticist or pediatric neurologist experienced in neuronal ceroid lipofuscinoses.

Age and Functional Requirements

Patient must meet ALL criteria:

  • Age 3 years or older at treatment initiation
  • Ambulatory status (able to walk with or without assistance)
  • CLN2 Clinical Rating Scale score of 3-6 on combined motor and language domains, with at least 1 point in each domain
Note: FDA approval has expanded to include children under 3, but Blue Shield California's current policy maintains the 3+ age requirement pending policy updates.

Step Therapy & Medical Exceptions

Brineura is exempt from traditional step therapy because it's the only FDA-approved disease-modifying treatment for CLN2 disease. However, Blue Shield requires documentation that:

  • No prior enzyme replacement therapy for CLN2 has been attempted
  • No previous stem cell or gene therapy for CLN2
  • Supportive care optimization has been considered alongside Brineura

Medical Exception Pathways

If coverage is initially denied, exceptions may be granted for:

  • Contraindications to required pre-treatments
  • Clinical urgency due to rapid disease progression
  • Access barriers to specialized testing or care

Quantity and Frequency Limits

Standard Authorization:

  • 300 mg per infusion (maximum dose)
  • Every 14 days (once every two weeks)
  • Initial authorization period: 6 months
  • Renewal requirements: Clinical assessment documenting benefit or stable function

Dose Modifications:

  • Lower doses may be approved for younger children based on clinical judgment
  • Frequency adjustments not typically covered outside standard protocol

Required Diagnostics and Documentation

Laboratory Requirements

Before Initial Authorization:

  • TPP1 enzyme activity results showing deficiency
  • Genetic testing (if enzyme testing unavailable) confirming pathogenic variants
  • Complete blood count and basic metabolic panel
  • Liver function tests baseline

Ongoing Monitoring:

  • CLN2 Clinical Rating Scale assessments every 6 months
  • Brain MRI annually to assess disease progression
  • Neurological evaluations by pediatric neurologist

Clinical Documentation Checklist

✓ Diagnosis confirmation with lab/genetic results
✓ Current functional status using standardized scales
✓ Treatment history and prior therapies attempted
✓ Specialist consultation notes from pediatric neurologist
✓ Surgical readiness assessment for device placement
✓ Family understanding of treatment requirements and expectations

Site of Care and Specialty Pharmacy Requirements

Approved Treatment Centers

Brineura must be administered at healthcare facilities meeting specific requirements:

Facility Requirements:

  • Trained personnel experienced in intraventricular administration
  • Emergency equipment including cardiopulmonary resuscitation capabilities
  • Hypersensitivity management protocols and medications
  • Neurosurgical consultation availability

Surgical Device Prerequisites:

  • Intraventricular access device must be implanted 5-7 days before first infusion
  • Codman® HOLTER RICKHAM Reservoirs with ventricular catheter preferred
  • Device patency confirmation before each infusion

Specialty Pharmacy Coordination

Blue Shield typically requires Brineura to be:

  • Dispensed through their designated specialty pharmacy network
  • Shipped directly to the infusion center
  • Coordinated with infusion scheduling and thawing protocols

Evidence to Support Medical Necessity

Clinical Guidelines and Evidence

Primary Supporting Evidence:

  • FDA approval for CLN2 disease in patients ≥3 years (FDA label)
  • Clinical trial data showing slowed functional decline
  • Consensus guidelines from CLN2 disease experts

Key Clinical Studies to Reference:

  • Phase 1/2 and Phase 2 studies demonstrating reduced motor and language decline
  • Brain volume preservation data compared to natural history
  • Safety profile in pediatric populations

Documentation Strategy

When submitting for authorization, include:

  1. Patient-specific rationale linking diagnosis to treatment indication
  2. Functional assessment showing current ambulatory status
  3. Prognosis without treatment based on natural history studies
  4. Treatment goals and expected outcomes
  5. Monitoring plan for ongoing assessment

Sample Medical Necessity Documentation

Medical Necessity Letter Template

"[Patient name] is a [age]-year-old child with confirmed CLN2 disease (neuronal ceroid lipofuscinosis type 2) diagnosed through [TPP1 enzyme deficiency/genetic testing showing pathogenic variants]. Current functional status demonstrates [specific CLN2 Clinical Rating Scale scores] with preserved ambulatory function.

CLN2 disease is a progressive neurodegenerative condition with inevitable loss of motor and cognitive function without disease-modifying therapy. Brineura (cerliponase alfa) is the only FDA-approved treatment that directly addresses the underlying enzyme deficiency and has demonstrated efficacy in slowing functional decline in clinical trials.

The patient meets all coverage criteria: confirmed CLN2 diagnosis, age ≥3 years, ambulatory status, and access to appropriate infusion facility. Without treatment, rapid neurological deterioration is expected based on natural history studies. Treatment will be administered at [facility name], which meets all safety and monitoring requirements.

Expected outcomes include slowed loss of ambulatory function and potential preservation of current developmental abilities. Regular monitoring will assess treatment response using standardized CLN2 rating scales."

Appeals Process in California

California offers robust appeal rights through two regulatory agencies depending on your plan type.

Internal Appeals (First Step)

Timeline: 30 days for standard appeals, 72 hours for urgent cases
Required: Submit through Blue Shield's member portal or provider system
Documentation: Include all supporting clinical evidence and specialist letters

Independent Medical Review (IMR)

For DMHC-regulated plans (most Blue Shield HMO and PPO plans):

  • Contact: DMHC Help Center at 888-466-2219
  • Timeline: 45 days for standard IMR, 7 days for expedited
  • Cost: Free to patients
  • Success rates: Variable, but California IMRs have overturned many specialty drug denials

For CDI-regulated plans:

  • Contact: California Department of Insurance at 800-927-4357
  • Similar timeline and process to DMHC IMR
Tip: California's IMR process is binding on insurers. Independent medical experts review the case and determine if treatment is medically necessary.

Common Denial Reasons and Solutions

Denial Reason Solution Strategy
Age under 3 years Request exception based on expanded FDA approval; provide clinical urgency documentation
Lack of ambulatory function Document current mobility status; provide CLN2 rating scale scores
Inadequate diagnostic testing Ensure both enzyme and genetic testing completed; provide lab reports
Site-of-care concerns Pre-approve infusion facility; provide facility credentials and safety protocols
"Experimental" designation Reference FDA approval and clinical trial data; cite peer-reviewed studies
Cost considerations Highlight lack of alternative treatments; document expected functional preservation
