Filsuvez (birch triterpenes topical gel) requires prior authorization from Blue Cross Blue Shield in California. For patients with junctional or dystrophic epidermolysis bullosa, the fastest path to approval involves: 1) Having your dermatologist or EB specialist submit a detailed PA request with confirmed EB subtype diagnosis and wound documentation, 2) If denied, file an internal appeal within 180 days citing California's step therapy protections, and 3) Request Independent Medical Review (IMR) through DMHC if needed—California's external review has strong overturn rates for specialty medications.

Why California State Rules Matter for Filsuvez Coverage

California's robust insurance regulations provide significant protections for patients seeking coverage of specialty medications like Filsuvez. Unlike many states, California has two insurance regulators: the Department of Managed Health Care (DMHC) oversees HMOs and most PPOs, while the California Department of Insurance (CDI) regulates other health policies.

For Blue Cross Blue Shield plans in California, most fall under DMHC oversight, which means you have access to California's Independent Medical Review (IMR) system—a powerful external appeal process with no cost to patients and binding decisions that insurers must follow.

Key California Advantages:

  • Strong step therapy override laws (AB 347) that protect rare disease patients
  • Automatic approval if insurers miss response deadlines
  • Free external review through IMR with high success rates for specialty drugs
  • Expedited timelines for urgent medical situations
Note: Self-funded employer plans (ERISA) may have different rules, though California's consumer protections often influence their practices.

Prior Authorization Timeline Standards

California law establishes strict timelines that Blue Cross Blue Shield must follow for Filsuvez prior authorization requests:

Standard vs. Urgent Timelines

Request Type BCBS Response Time California Law
Standard PA 72 hours for non-urgent Required by state
Urgent/Expedited PA 24 hours Required by state
Step Therapy Exception 72 hours (auto-approved if missed) AB 347
Internal Appeal 30 days standard, 72 hours expedited DMHC requirement

When to Request Expedited Review

For epidermolysis bullosa patients, you can request expedited review if:

  • Wounds are worsening without treatment
  • Risk of infection or complications exists
  • Current wound care is inadequate

Script for requesting expedited review: "This is a request for expedited prior authorization review due to urgent medical necessity. The patient has confirmed epidermolysis bullosa with active wounds requiring immediate specialized treatment to prevent complications."

California Step Therapy Protections for EB

California's AB 347 provides strong protections against inappropriate step therapy requirements for rare diseases like epidermolysis bullosa. Step therapy exceptions must be granted when the required first-line medication is inconsistent with good professional practice.

Medical Exception Criteria

Your doctor can request a step therapy override if standard wound treatments:

  • Are contraindicated or likely to cause adverse reactions
  • Will worsen your condition or decrease daily functioning
  • Create significant barriers to adherence
  • Have already been tried and proven ineffective

Required Documentation for EB Patients

When submitting step therapy exception requests, include:

  • Complete treatment history with specific dates
  • Reasons for discontinuation of previous therapies
  • Documentation of contraindications or prior failures
  • Specialist confirmation of EB subtype (junctional or dystrophic)
  • Wound assessment showing medical necessity for birch triterpenes
Tip: If Blue Cross Blue Shield fails to respond within 72 hours, your step therapy exception is automatically approved for the duration of the prescription.

Continuity of Care During Treatment Transitions

California provides continuity of care protections when transitioning between treatments or insurance plans. While specific epidermolysis bullosa continuity rules weren't found in our research, general protections include:

  • Up to 12 months of continued provider relationships under Medi-Cal managed care
  • Transition coverage during plan changes
  • Emergency continuation for ongoing specialty treatments

For current continuity protections specific to Filsuvez and EB care, contact the DMHC Help Center at 888-466-2219.

External Review and DMHC Complaints

California's Independent Medical Review (IMR) system provides a powerful final appeal option with no cost to patients and decisions that are binding on insurers.

IMR Timeline and Process

  1. Complete internal appeals with Blue Cross Blue Shield first
  2. File IMR application within 6 months of final denial
  3. DMHC assigns independent medical experts to review your case
  4. Decision timeline: 45 days standard, 7 days for urgent cases

IMR Success Rates for Specialty Drugs

Independent Medical Review has demonstrated strong success rates for specialty medications, with some plans showing 60-70% overturn rates when proper clinical documentation supports medical necessity.

How to File IMR

  • Online: DMHC website (healthhelp.ca.gov)
  • Phone: 888-466-2219 (DMHC Help Center)
