The purpose of this legislation, known as the "Seniors' Access to Critical Medications Act of 2025," is to allow certain outpatient prescription drugs to be prescribed and dispensed by physicians without violating existing self-referral rules under the Medicare program. This aims to improve access to medications for seniors and streamline the process for obtaining necessary drugs. Key provisions of the legislation include an exception to the physician self-referral prohibition for specific outpatient prescription drugs that are covered under Medicare Part D.
