How to Get Epidiolex (Cannabidiol) Covered by Blue Cross Blue Shield in Washington: Complete 2025 Guide

Quick Answer: Getting Epidiolex Covered in Washington

Epidiolex (cannabidiol) requires prior authorization from Blue Cross Blue Shield plans in Washington, including Premera and Regence. You'll need confirmed diagnosis of Lennox-Gastaut syndrome, Dravet syndrome, or tuberous sclerosis complex seizures, plus documented failure of at least 2 generic anti-seizure medications. Your neurologist submits the PA request with supporting evidence. If denied, Washington's external review process through an Independent Review Organization (IRO) provides a strong appeals pathway with decisions binding on insurers.

First step today: Contact your neurologist to gather seizure logs, prior medication records, and begin the prior authorization paperwork through your plan's provider portal.

Coverage Basics

Is Epidiolex Covered by Blue Cross Blue Shield in Washington?

Yes, but with restrictions. Epidiolex requires prior authorization across all Blue Cross Blue Shield plans, including Washington's major carriers:

  • Premera Blue Cross (largest BCBS affiliate in Washington)
  • Regence BlueShield (serves Washington, Oregon, Utah, Idaho)

The medication isn't listed on standard formularies without prior approval requirements. Coverage depends on meeting specific medical criteria outlined in your plan's utilization management guidelines.

Which Conditions Qualify?

Epidiolex is FDA-approved for seizures associated with:

  • Lennox-Gastaut syndrome (LGS)
  • Dravet syndrome
  • Tuberous sclerosis complex (TSC)

Off-label use for other epilepsy conditions faces higher denial rates and requires stronger medical necessity documentation.

Prior Authorization Process

Step-by-Step: Fastest Path to Approval

  1. Neurologist gathers documentation (1-2 days)
    • Confirmed diagnosis via EEG, genetic testing, or MRI
    • 4-week seizure diary showing current frequency
    • Records of at least 2 failed generic anti-seizure medications
    • Recent liver function tests (ALT, AST, bilirubin)
  2. Submit PA request (same day)
    • Use your plan's provider portal or fax submission
    • Include medical necessity letter citing FDA labeling
    • Attach all supporting clinical documentation
  3. Plan review (15 business days standard, 72 hours expedited)
    • Utilization management team reviews against criteria
    • May request additional information or peer-to-peer review
  4. Approval and specialty pharmacy setup (1-3 days)
    • Prescription transferred to designated specialty pharmacy
    • Patient contacted for delivery coordination

Required Documentation Checklist

✓ Diagnosis confirmation:

  • LGS: EEG showing drop seizures and slow spike-wave patterns
  • Dravet: SCN1A genetic testing results
  • TSC: Brain MRI showing cortical tubers/nodules, genetic testing

✓ Prior medication trials: Names, doses, duration (minimum 4 weeks each), and specific reasons for discontinuation

✓ Current seizure burden: Detailed log showing frequency and types over past 4 weeks

✓ Baseline labs: Liver function tests within past 30 days

✓ Medical necessity letter: Neurologist statement explaining why Epidiolex is medically appropriate

Timing and Urgency

Standard Timeline

  • PA submission to decision: 15 business days
  • Expedited review: 72 hours (requires physician certification of urgency)
  • Appeals: 30 days for internal, 45 days for external IRO review

When to Request Expedited Review

Contact your plan immediately for expedited processing if:

  • Seizures occur more than weekly

  • Patient is hospitalized or at risk of serious harm
Tip: Document urgency in writing. Include physician statement that delay in treatment could seriously jeopardize health or ability to regain maximum function.

Step Therapy Requirements

Blue Cross Blue Shield plans typically require trial and failure of at least 2 generic anti-seizure medications before approving Epidiolex. Common required trials include:

Valproate 6-12 weeks Weight gain, hair loss, tremor
Levetiracetam 4-8 weeks Behavioral problems, somnolence

Topiramate 6-10 weeks Cognitive effects, kidney stones

Documenting Step Therapy Failures

For each prior medication, provide:

  • Specific dose reached and duration of trial

  • Reason for discontinuation (ineffective, intolerable side effects, contraindication)
  • Supporting notes from treating neurologist

Costs and Copay Assistance

Denials and Appeals

Common Denial Reasons and Solutions

Denial Reason How to Address
Insufficient prior trials Provide detailed records of ≥2 generic AED failures with specific doses, durations, and outcomes
Diagnosis not confirmed Submit EEG reports, genetic testing, or MRI results confirming LGS, Dravet, or TSC
Dose exceeds quantity limits Include weight-based dosing calculation and FDA labeling supporting requested dose
Missing monitoring labs Submit recent liver function tests and monitoring plan
Off-label use Provide peer-reviewed literature and medical society guidelines supporting use

Internal Appeals Process

  1. Request peer-to-peer review with plan's medical director
  2. Submit written appeal within 180 days of denial
  3. Include additional evidence addressing specific denial reasons
  4. Request expedited appeal if clinically urgent
From our advocates: We've seen success when families work closely with their neurologist to document not just that other medications failed, but specifically how they failed—whether due to lack of efficacy at maximum tolerated doses or intolerable side effects that prevented therapeutic dosing. This detailed narrative often makes the difference in appeals.
