Why Washington State Rules Matter

Washington provides some of the strongest consumer protections for specialty drug coverage in the nation. Unlike many states, Washington law prohibits insurers from forcing substitution of nonpreferred drugs with preferred alternatives unless medically necessary (RCW 48.43.0961). This means if you're stable on Haegarda, Aetna CVS Health can't simply switch you to a cheaper alternative without clinical justification.

The state also requires independent external review for all coverage denials, taking final decisions out of the insurer's hands. Washington's Office of Insurance Commissioner (OIC) provides free consumer advocacy at 1-800-562-6900 and maintains certified Independent Review Organizations (IROs) with medical experts who understand rare diseases like hereditary angioedema.

Note: These protections apply to most commercial plans, but self-funded employer plans (ERISA) may have different appeal processes. Ask your HR department about your plan type.

Counterforce Health helps patients navigate these complex appeal processes by analyzing denial letters and crafting evidence-based rebuttals that align with payer policies and state regulations.

Step Therapy Protections

If Aetna requires you to try other HAE medications first (step therapy), Washington law provides medical exception criteria. Your doctor can request a step therapy override if:

  • Prior therapy failed: Document inadequate response to required medications
  • Prior therapy caused harm: Allergic reactions, intolerable side effects
  • Contraindication exists: Medical reason you can't use preferred drug
  • Delay would be harmful: Urgent medical need for immediate treatment

Documentation That Helps

When requesting step therapy override, include these specific phrases in your appeal:

  • "Patient experienced therapeutic failure with [specific drug] despite adequate trial duration"
  • "Contraindicated due to [specific medical condition/allergy]"
  • "Delay in treatment poses significant risk of [specific harm]"
  • "Clinical guidelines support use of Haegarda in this patient population"

Continuity of Care Rights

Washington's continuity protections ensure you can maintain Haegarda therapy during transitions:

Network Changes

If your HAE specialist leaves Aetna's network, you have rights to:

  • 90 days continued coverage at in-network rates
  • Notification requirement: 30 days advance notice from Aetna
  • Transition planning: Time to find new in-network provider

Formulary Changes

If Aetna removes Haegarda from formulary:

  • Advance notice required: 60 days before change
  • Exception process available: Medical necessity review
  • Grandfathering possible: Existing patients may continue coverage

External Review Process

Washington's independent external review gives you a final appeal option when Aetna denies coverage:

How to Request External Review

  1. Complete Internal Appeals: Must exhaust Aetna's internal process first
  2. File Within 180 Days: From final internal denial
  3. Submit to OIC: Call 1-800-562-6900 or use online form
  4. IRO Assignment: OIC assigns certified Independent Review Organization
  5. Medical Review: IRO panel includes specialists familiar with HAE
  6. Final Decision: Binding determination within 30 days

What the IRO Reviews

  • Medical necessity: Is Haegarda appropriate for your condition?
  • Plan terms: Does your policy cover this treatment?
  • Clinical evidence: Do medical records support coverage?
  • Standard of care: Is denial consistent with medical practice?

Common Denial Reasons & Solutions

Denial Reason How to Overturn Required Documentation
"Not medically necessary" Provide HAE attack logs and specialist letter Emergency room visits, acute treatment records
"Experimental/investigational" Cite FDA approval for HAE prophylaxis FDA label for Haegarda
"Step therapy required" Document failure of preferred alternatives Trial records for C1-INH, lanadelumab, or berotralstat
"Non-formulary drug" Request formulary exception Medical necessity letter with clinical rationale
