Doctor Knows Best Act of 2023

This bill prohibits health insurance plans and federal health programs from requiring prior approvals, step therapy (like forcing patients to try cheaper treatments first), or medical necessity reviews for covered services. It directly affects patients receiving health insurance coverage (both private plans and federal programs like Medicare) and their doctors, who will no longer face these administrative barriers for treatments already covered. The law applies to all group and individual health insurance plans starting January 1, 2024, and extends to federal health programs by the same date. It removes specific hurdles that previously delayed or denied care, though it does not change which services are covered.
