To amend the Public Health Service Act to direct the Secretary of Health and Human Services to establish drug adherence guidelines, and for other purposes.

This bill requires the HHS Secretary to create drug adherence guidelines aiming for 90% medication adherence among Medicare Part B and D drug users. It mandates using AI and machine learning technologies in developing these guidelines and prioritizes promoting generic and biosimilar drugs where possible. The policy directly affects Medicare beneficiaries and providers by setting a measurable adherence target for covered drugs. Key changes include new federal guidelines focused on improving medication consistency through technology and cost-effective drug options.
