The main purpose of this legislation, known as the Prevent Interruptions in Physical Therapy Act of 2025, is to allow physical therapists to use locum tenens arrangements under Medicare. Locum tenens arrangements enable healthcare providers to temporarily fill in for one another, ensuring that patients continue to receive care without interruption when their regular provider is unavailable. Key provisions of this legislation include an amendment to the Social Security Act that specifically adds physical therapists to the list of providers who can utilize locum tenens arrangements.
