Why Washington State Rules Matter

Washington has some of the strongest patient protections in the country for specialty medications like Opsumit (macitentan). The state requires insurers to provide clear step therapy override processes, maintain continuity of care during plan transitions, and respond to emergency appeals within 24 hours.

These protections work alongside Aetna CVS Health's own policies to create multiple pathways for coverage. Washington's external review process through Independent Review Organizations (IROs) gives you a final appeal option where medical experts—not insurance company employees—make binding coverage decisions.

Note: If you have an employer-sponsored ERISA plan, some state protections may not apply, but many large employers voluntarily follow Washington's appeal standards.

Washington's Step Therapy Protections

Washington law provides strong protections against inappropriate step therapy requirements. Since January 2021, insurers must allow step therapy overrides when:

  • The required drug was ineffective for you previously
  • The required drug is expected to be ineffective or cause harm based on your clinical characteristics
  • You're stable on your current medication and switching could threaten your health

Emergency Override Process: If Aetna requires step therapy for Opsumit, your doctor can request an emergency override. Washington law requires insurers to respond within 24 hours for urgent requests. If they don't respond in time, the override is automatically approved.

From our advocates: We've seen patients successfully argue that switching from a stable PAH therapy to try other medications first could worsen their functional status and increase hospitalization risk. Document your current stability and the potential consequences of delays.

Appeals Process: Internal to External Review

Internal Appeals with Aetna

Level 1: Standard Appeal

  • Deadline: 180 days from denial
  • Timeline: 30 days for decision (14 days for urgent)
  • How to file: Call 1-800-CVS-CARE or submit through member portal

Level 2: Peer-to-Peer Review

  • Request clinical review with Aetna's medical director
  • Your prescriber discusses the case directly
  • Often resolves coverage disputes faster than formal appeals

External Review in Washington

If internal appeals fail, Washington's external review process provides independent medical review:

Timeline and Process:

  • Deadline to file: 21 calendar days after final internal denial
  • IRO assignment: Within 3 working days
  • Decision: 15 calendar days (72 hours for expedited)
  • Cost: Free to you (insurer pays)

How to Request External Review: Contact the Washington Office of Insurance Commissioner at 1-800-562-6900 or file online. The OIC will assign an Independent Review Organization with PAH specialists to review your case.

What Makes External Review Powerful: The IRO's decision is binding on Aetna. Medical experts review whether the denial was appropriate based on medical necessity, not just plan rules.

What if Opsumit isn't on my Aetna formulary? You can request a formulary exception by documenting medical necessity and providing clinical justification for why formulary alternatives aren't appropriate.

How do I prove medical necessity for Opsumit? Document your PAH diagnosis, functional class, prior therapies, and treatment goals. Include right heart catheterization results and specialist assessments.
