Summary

Premera HMO is implementing significant prior authorization and coverage changes for multiple drug categories effective January 3, 2025, including new step therapy requirements for cancer drugs (HER2 inhibitors moving biosimilars to first-line), stricter criteria for asthma medications (IL-5 inhibitors requiring higher eosinophil counts), and new coverage criteria for multiple sclerosis treatments. These changes will require prior authorization documentation and affect billing for oncology, pulmonology, and neurology practices.

Providers must update documentation templates to include new medical necessity criteria including specific lab values, previous medication trials, and specialist consultation requirements.
