Why Washington State Rules Matter

Washington has some of the strongest insurance consumer protections in the nation, which directly impact how Blue Cross Blue Shield plans handle vigabatrin coverage decisions. Under RCW 48.43.535, all health carriers—including Premera Blue Cross and Regence BlueShield (the major BCBS plans in Washington)—must follow specific timelines and procedures for specialty drug appeals.

These state rules interact with BCBS's national formulary policies in important ways. While the basic prior authorization criteria for vigabatrin remain consistent across BCBS plans, Washington's expedited appeal requirements and mandatory external review process give patients additional leverage when initial coverage requests are denied.

Prior Authorization Requirements & Timelines

Urgent vs. Non-Urgent Review Standards

Washington regulations require BCBS plans to distinguish between urgent and standard prior authorization requests. For vigabatrin, which treats serious seizure disorders, most requests qualify for expedited processing.

Urgent criteria (72-hour review):

  • Infantile spasms with developmental regression
  • Breakthrough seizures on current therapy
  • Hospital discharge requiring immediate medication access

Standard timeline: 14 days for non-urgent requests

REMS Enrollment: The Critical First Step

Before any coverage consideration, all parties must enroll in the Vigabatrin REMS program:

  1. Prescriber certification: Review prescribing information, commit to vision monitoring, agree to counsel patients on risks
  2. Patient/guardian enrollment: Complete agreement form with prescriber, acknowledge vision loss risks
  3. Pharmacy verification: Obtain Authorization to Dispense (ATD) code for each prescription
Tip: REMS enrollment can take 2-3 business days. Start this process before submitting the prior authorization to avoid delays.

Medical Necessity Documentation

BCBS requires specific clinical documentation depending on the indication:

For Infantile Spasms:

  • Confirmed diagnosis in patients ≤2 years
  • EEG showing hypsarrhythmia or modified hypsarrhythmia
  • Documentation that benefits outweigh vision loss risks
  • Baseline ophthalmologic assessment

For Refractory Complex Partial Seizures:

  • Age ≥2 years
  • Adjunctive therapy after failure of several other antiepileptic drugs
  • Specialist (neurologist) involvement
  • Creatinine clearance >10 mL/min

Step Therapy Protections in Washington

Washington's step therapy reform law (HB 1879) provides significant protections for epilepsy patients. Under this law, BCBS must approve step therapy override exceptions when specific criteria are met.

Override Criteria

Plans must grant exceptions if the prescriber attests that:

  • Patient is stable on the requested drug from prior coverage
  • Patient tried and failed the preferred drug within the past 365 days
  • Patient had an adverse reaction or contraindication to the preferred drug
  • The condition is life-threatening or rapidly worsening (epilepsy qualifies due to seizure risks)

Timeline Requirements

  • Response deadline: 3-5 business days for override requests
  • Auto-approval: If the plan doesn't respond within the required timeframe
  • Maximum step therapy period: 30 days (with possible 7-day extension if clinically justified)
Note: These protections apply to all BCBS plans in Washington, including employer-sponsored plans that voluntarily follow state regulations.

Continuity of Care & Ongoing Therapy

Renewal Requirements

Vigabatrin prior authorizations typically require renewal every 3 months for infantile spasms and every 6 months for refractory seizures. Washington law requires plans to provide adequate notice before coverage termination.

Renewal documentation must include:

  • Evidence of continued clinical benefit
  • Updated vision monitoring results
  • Confirmation of ongoing REMS enrollment
  • Assessment of developmental progress (for infantile spasms)

Grace Periods for Transitions

When transitioning between plans or coverage periods, Washington requires a minimum 30-day grace period for ongoing specialty medications. During this time, patients can continue current therapy while the new prior authorization is processed.

External Review & Consumer Protections

Washington's external review process under RCW 48.43.535 provides a powerful tool for overturning BCBS denials. This process is binding on the insurer and conducted by independent medical specialists.

When You're Eligible

External review is available after exhausting internal appeals for:

  • Coverage denials for medically necessary services
  • Adverse benefit determinations
  • Disputes over medical necessity definitions

How to File

  1. Request deadline: Up to 180 days from final internal denial
  2. Submission method: Contact the Washington Office of Insurance Commissioner at 1-800-562-6900 or submit online
  3. Required documents: Final denial letter, member ID, medical records, explanation of why the denial is incorrect
  4. Cost: Free to patients

Timeline and Process

  • Standard review: Decision within 45 days
  • Expedited review: Decision within 72 hours for urgent cases
  • Carrier cooperation: BCBS must provide all relevant records to the Independent Review Organization (IRO) within 3 business days
  • Patient submission time: At least 5 business days to provide additional evidence
From our advocates: We've seen many vigabatrin denials overturned through Washington's external review process, particularly when families provide comprehensive documentation of failed alternatives and the urgent nature of seizure control. The key is presenting a complete clinical picture that demonstrates medical necessity according to established guidelines.

Practical Scripts & Appeal Language

Patient Phone Script for BCBS

"I'm calling about a prior authorization denial for vigabatrin (PA reference number: ____). This medication is FDA-approved for my child's infantile spasms, and we've completed all REMS requirements. Under Washington state law, I'm requesting an expedited internal appeal because delayed treatment risks developmental regression. Can you please transfer me to the appeals department and provide the expedited review form number?"

Medical Necessity Appeal Paragraph

"This request for vigabatrin coverage meets all medical necessity criteria under BCBS policy [policy number]. The patient has confirmed infantile spasms with EEG documentation of hypsarrhythmia, is within the FDA-approved age range (1 month-2 years), and has completed baseline vision screening. Per Washington state step therapy protections under HB 1879, any required step therapy should be waived given the urgent nature of this life-threatening condition and the lack of equally effective alternatives for infantile spasms."

Citing State Rules in Appeals

Reference specific Washington regulations to strengthen your appeal:

  • "Under RCW 48.43.535, I am requesting external review of this adverse benefit determination"
  • "Per WAC 284-43-210, this urgent condition requires 72-hour processing"
  • "Washington's step therapy reform law requires exception approval for this life-threatening condition"

Coverage Limits & ERISA Plans

Self-Funded Employer Plans

While Washington state insurance laws don't automatically apply to self-funded employer plans governed by ERISA, many large employers voluntarily adopt similar procedures. If your BCBS plan is self-funded and doesn't follow Washington's external review process, you can contact the U.S. Department of Labor at 866-444-3272 for ERISA plan appeals guidance.

Medicaid (Apple Health) Considerations

For Medicaid-related denials in Washington (Apple Health), the appeals process differs slightly. Contact 800-562-3022 for Medicaid-specific guidance, though managed care enrollees may also access independent review through the same IRO process.

FAQ

How long does BCBS prior authorization take for vigabatrin in Washington? Standard requests take up to 14 days, but urgent cases (like infantile spasms with regression) must be processed within 72 hours under Washington regulations.

What if vigabatrin is non-formulary on my BCBS plan? You can request a formulary exception by demonstrating medical necessity and lack of formulary alternatives. Washington's step therapy protections may apply if preferred drugs are contraindicated.

Can I request an expedited appeal if BCBS denies coverage? Yes, if delayed access would risk serious health impairment. For seizure disorders, this typically qualifies as urgent. Internal appeals must be processed within 72 hours for urgent cases.

Does step therapy apply if I've used vigabatrin successfully outside Washington? Under Washington's step therapy reform law, if you were stable on vigabatrin within the past 365 days, plans must approve override exceptions without requiring you to retry preferred alternatives.

What happens if the external review upholds BCBS's denial? The IRO decision is binding, but you can still contact the Washington Office of Insurance Commissioner for additional guidance or file a complaint if you believe the process was mishandled.

How much does vigabatrin cost without insurance in Washington? Generic vigabatrin costs approximately $4,557 for 100×500mg tablets, while brand Sabril can cost over $19,000. Counterforce Health can help identify manufacturer assistance programs and appeal strategies to reduce out-of-pocket costs.

Are there patient assistance programs for vigabatrin? Yes, Lundbeck (Sabril manufacturer) and generic manufacturers offer patient assistance programs. Additionally, organizations like the Epilepsy Foundation may provide guidance on financial assistance options.

What if my employer plan doesn't follow Washington state rules? Self-funded ERISA plans aren't bound by state insurance laws, but many voluntarily adopt similar procedures. Contact the U.S. Department of Labor at 866-444-3272 for ERISA-specific appeals guidance.
