Why Washington State Rules Matter

Washington provides some of the strongest consumer protections in the nation for insurance appeals, especially important for expensive specialty drugs like Busulfex. The state's regulations work alongside federal Medicare rules to give you additional rights and faster resolution paths.

Key Washington Advantages:

  • Robust step therapy exceptions under WAC 284-43-5080 that go beyond federal minimums
  • Independent Review Organizations (IROs) that can override Humana's denials
  • Active consumer advocacy through the Office of Insurance Commissioner
  • Expedited review timelines for urgent medical situations like transplant preparation

These protections apply to Humana Medicare Advantage plans, though self-funded employer plans may have different rules.

Step Therapy Protections in Washington

Washington Administrative Code (WAC) 284-43-5080 provides comprehensive protections against inappropriate step therapy requirements. You can request a medical exception if:

Automatic Exception Criteria:

  • The required step therapy drug is contraindicated or likely to cause adverse reactions
  • The drug is expected to be ineffective based on clinical history
  • You've already tried the required drug or similar medication without success
  • You're stable on current therapy and switching would risk safety or efficacy

For HSCT Conditioning Regimens:

  • Document the critical timing of transplant preparation
  • Cite any prior conditioning regimen failures or intolerances
  • Reference the medical urgency that makes step therapy inappropriate

Appeal Language for Step Therapy: "In accordance with WAC 284-43-5080, a medical exception to step therapy is requested based on [contraindication/prior failure/clinical urgency]. The patient requires immediate access to Busulfex for hematopoietic stem cell transplant conditioning, and delays could compromise transplant success."
