Understanding Humana's Uplizna (inebilizumab) Coverage

Uplizna (inebilizumab) is covered under Medicare Part B as a physician-administered infusion drug, not Part D pharmacy benefits. This means it's processed through Humana's medical benefit with specific prior authorization requirements for both approved indications:

  • AQP4-IgG positive NMOSD (neuromyelitis optica spectrum disorder) in adults
  • IgG4-related disease in adults (newly approved in 2025)

The drug carries a significant cost—approximately $140,000 per dose with year-one treatment costs around $420,000—making prior authorization nearly universal across all payers.

Note: Humana has committed to reducing prior authorization requirements by one-third and processing 95% of electronic requests within one business day by January 2026, but Uplizna remains on the PA list due to its high cost and specialized use.

Appeals Process in Michigan

Internal Appeal with Humana

Timeline: 65 days from denial notice
How to file: Same portal/fax used for original PA
Required documents:

  • Copy of denial letter
  • Updated medical necessity letter addressing denial reasons
  • Additional clinical evidence
  • Provider attestation of medical necessity

Decision timeline:

  • Standard: 30 days for pre-service, 60 days for post-service
  • Expedited: 72 hours if urgent medical need

Michigan DIFS External Review

If Humana's internal appeal is unsuccessful, Michigan residents have additional protection through the state's external review process.

Timeline: 127 days from final denial
How to file: Online form or mail/fax paper form
Cost: Free to patients
Decision timeline:

  • Standard: Up to 60 days
  • Expedited: 72 hours with physician letter stating delay would jeopardize health
From our advocates: We've seen Michigan DIFS external reviews succeed when the internal appeal documentation clearly shows the patient meets medical necessity criteria but the insurer applied overly restrictive interpretations. The key is presenting a comprehensive clinical picture that demonstrates both the severity of the condition and the appropriateness of Uplizna specifically.

Required for expedited review:

  • Written statement from treating physician
  • Documentation that delay could seriously jeopardize life, health, or ability to regain function
  • Must be for pre-service denial (treatment not yet received)

Contact DIFS: 877-999-6442 (Mon-Fri, 8 AM-5 PM) for assistance with the appeal process.
