Understanding Washington State Prior Authorization Laws

Washington state provides robust consumer protections that work alongside Blue Cross Blue Shield policies to ensure fair coverage decisions. These protections are especially important for rare disease medications like Opfolda.

Why State Rules Matter

Washington's insurance laws apply to fully-insured Blue Cross Blue Shield plans (like Premera Blue Cross and Regence BlueShield), but not to self-funded employer plans governed by ERISA. If you're unsure which type of plan you have, check your insurance card or call member services.

Key Timeline Standards

Under Washington law, Blue Cross Blue Shield must:

  • Respond to standard prior authorization requests within 30 days
  • Provide expedited reviews within 72 hours for urgent medical situations
  • Allow at least 180 days from a final denial to request external review

Blue Cross Blue Shield Coverage Requirements for Opfolda

Opfolda (miglustat) is an oral enzyme stabilizer that must be used with Pombiliti for late-onset Pompe disease (LOPD). It's never effective as monotherapy and is only approved for adults weighing at least 40 kg.

Coverage at a Glance

Requirement What It Means Where to Find It
Prior Authorization Required for all Blue Cross plans Premera PA requirements
Age/Weight Limits Adults ≥40 kg only FDA labeling
Combination Therapy Must be prescribed with Pombiliti Manufacturer guidelines
ERT History Must show inadequate response to current enzyme replacement therapy Clinical documentation
Specialist Involvement Typically requires neuromuscular specialist Provider network
Note: Since Blue Cross Blue Shield operates as independent plans in Washington (primarily Premera and Regence), specific coverage criteria may vary. Always verify with your specific plan.

Step-by-Step: Fastest Path to Approval

1. Confirm Your Diagnosis and Eligibility

Who: Your specialist (typically a neuromuscular or metabolic specialist) What: Document confirmed LOPD diagnosis with genetic testing or enzyme assay Timeline: Before PA submission Source: FDA Opfolda labeling

2. Document ERT Treatment History

Who: Your care team What: Detailed records showing current or previous enzyme replacement therapy and inadequate response Include: Medication names, doses, duration, and clinical outcomes (6MWT, FVC, etc.)

3. Submit Prior Authorization Request

Who: Your prescribing physician's office What: Complete PA form with all supporting documentation How: Through Blue Cross provider portal or fax Timeline: Allow 30 days for standard review

4. Include Required Clinical Information

  • Confirmed LOPD diagnosis (ICD-10 code)
  • Current weight (must be ≥40 kg)
  • Current ERT regimen and response
  • Plan for combination therapy with Pombiliti
  • Weight-based dosing plan (195 mg for 40-<50 kg; 260 mg for ≥50 kg)

5. Request Expedited Review if Urgent

When: If delays could harm your health How: Provider requests expedited review citing medical urgency Timeline: 72-hour response required

Washington's Step Therapy Protections

Washington state requires Blue Cross Blue Shield to provide step therapy exceptions when medically appropriate. For Opfolda, this is particularly relevant since it's often prescribed after trying other enzyme replacement therapies.

Medical Exception Criteria

You can request a step therapy override if:

  • Previous ERT was ineffective or caused adverse reactions
  • Current therapy is working and switching would be disruptive
  • FDA labeling doesn't support the required first-line drug for your specific condition
  • Patient safety would be compromised by the required drug

Documentation for Step Therapy Override

Your doctor should submit a step therapy exception request including:

  • Clinical notes showing previous treatment failures
  • Adverse reaction history if applicable
  • Specialist recommendation for Opfolda/Pombiliti combination

Appeals Process: Internal and External Review

If Blue Cross Blue Shield denies your Opfolda request, Washington provides a strong appeals process with multiple levels of protection.

Internal Appeals (First Step)

Timeline: 30 days from denial notice Process: Submit written appeal to Blue Cross Blue Shield Include:

  • Denial letter
  • Additional medical records
  • Provider letter explaining medical necessity

External Review (Independent Review Organization)

Washington's external review process is particularly powerful for rare disease medications. Under RCW 48.43.535:

When to Use: After internal appeals are exhausted or if Blue Cross misses deadlines Timeline: 180 days from final internal denial to request Process:

  1. Submit external review request to Blue Cross Blue Shield
  2. Blue Cross assigns certified Independent Review Organization (IRO) within 3 days
  3. IRO receives all records within 3 days
  4. You get 5 business days to submit additional information
  5. IRO decision within 30 days (72 hours for expedited cases)

Key Advantage: The IRO can override Blue Cross's medical necessity standards if they're inconsistent with evidence-based practice.

From our advocates: We've seen Washington's external review process work particularly well for rare disease cases. The key is submitting a comprehensive packet that includes specialist letters, FDA labeling excerpts, and clear documentation of why the patient meets clinical criteria. One family successfully overturned a denial by highlighting that the patient's weight and ERT history clearly met FDA-approved indications.

Common Denial Reasons and How to Fix Them

Denial Reason How to Overturn
"Requested as monotherapy" Resubmit with Pombiliti co-prescription and combination therapy plan
"Patient doesn't meet weight criteria" Provide current weight documentation showing ≥40 kg
"No evidence of ERT failure" Submit detailed treatment history with objective measures (pulmonary function, 6MWT)
"Not medically necessary" Include specialist letter citing FDA labeling and clinical guidelines
"Experimental/investigational" Reference FDA approval and cite manufacturer clinical data

Costs and Patient Assistance Options

Opfolda's U.S. pricing hasn't been separately disclosed, but the combination therapy is expensive. Assistance options include:

  • Amicus Assist Program: Patient support services from the manufacturer
  • Washington State Prescription Drug Program: For eligible residents
  • Patient Advocate Foundation: Copay assistance for qualifying patients
  • HealthWell Foundation: Grants for rare disease medications

Contact Amicus Therapeutics directly for current assistance programs.

When to Contact Washington Regulators

Contact the Washington Office of the Insurance Commissioner if:

  • Blue Cross Blue Shield misses appeal deadlines
  • You need help understanding your appeal rights
  • You want to file a complaint about the coverage process

Consumer Advocacy Line: 1-800-562-6900

The OIC provides appeal letter templates and can guide you through the external review process.

Special Considerations for Different Plan Types

Self-Funded ERISA Plans: If your Blue Cross plan is self-funded through your employer, Washington state law doesn't apply. Instead, you have federal external review rights under the Affordable Care Act, with similar timelines but different procedures.

Apple Health (Medicaid): Washington Medicaid has its own fair hearing process through the Office of Administrative Hearings, separate from commercial insurance appeals.
