Coverage Basics: Is Isturisa Covered?

Yes, Humana covers Isturisa (osilodrostat), but with restrictions. The medication is placed on Tier 5 (specialty tier) of Humana's Medicare formularies, including their 2025 Premier Rx and Value Rx plans. This placement means:

  • Prior authorization required for all prescriptions
  • Specialty pharmacy dispensing only (not available at regular retail pharmacies)
  • Highest copay tier (typically 25-33% coinsurance after deductible)
  • Quantity limits may apply (commonly 60 tablets per 30 days)
Note: Humana is eliminating prior authorization for about one-third of outpatient services starting January 2026, but specialty medications like Isturisa will likely remain subject to review.

Specialty Pharmacy Requirements

Why Specialty Pharmacy?

Humana requires Tier 5 medications like Isturisa to be dispensed through designated specialty pharmacies due to:

  • High cost requiring special handling
  • Need for patient education and monitoring
  • Storage and shipping requirements
  • Clinical support services

Humana's Specialty Pharmacy Network

Common specialty pharmacies in Humana's network include:

  • Accredo Specialty Pharmacy
  • CVS Specialty
  • Humana Pharmacy (specialty division)

What to Expect

  • Initial consultation: Pharmacist will review medication, side effects, and monitoring
  • Home delivery: Medications shipped directly to your home

When Counterforce Health helps patients navigate specialty drug approvals, we often see faster resolution when the specialty pharmacy is engaged early in the process, as they can provide additional clinical support for the prior authorization.
