What This Guide Covers

This guide helps hemophilia A patients and their healthcare providers navigate Humana's prior authorization process for Hemlibra (emicizumab-kxwh) in Washington state. Whether you're dealing with an initial request or appealing a denial, we'll walk through the specific requirements, timelines, and appeal rights unique to Washington residents.

Hemlibra is FDA-approved for routine prophylaxis in hemophilia A patients with or without FVIII inhibitors, but insurance coverage requires demonstrating medical necessity through proper documentation and adherence to payer-specific protocols.

Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals for specialty medications like Hemlibra. Our platform analyzes denial letters and plan policies to draft point-by-point rebuttals that align with each payer's specific requirements.

Before You Start: Verify Your Coverage

Check Your Plan Type and Coverage

Coverage Type What It Means Where Hemlibra Is Covered
Medicare Advantage Integrated Part C plan with Part D drug coverage Part D prescription benefit (not Part B medical)
Commercial/ACA Employer or marketplace plan Prescription drug benefit, likely specialty tier

  • Your specific plan type and formulary
  • Whether prior authorization is required
  • Your plan's specialty pharmacy requirements

From Our Advocates

"We've seen many Hemlibra denials overturned when families provide detailed bleeding logs showing the frequency and impact of episodes. One patient's appeal succeeded after documenting 15 bleeding episodes in six months despite factor VIII prophylaxis, demonstrating clear medical necessity for Hemlibra's superior protection. The key was showing not just the number of bleeds, but their impact on school attendance and daily activities."
