This bill proposes an amendment to Title XVIII of the Social Security Act, specifically concerning Medicare provisions for healthcare providers. Its central aim is to extend the ability to utilize locum tenens arrangements to physical therapists, a provision currently available to physicians. The legislation would modify section 1842(b)(6) of the Social Security Act, enabling physical therapy practices to engage temporary substitute therapists. This ensures uninterrupted patient care for outpatient physical therapy services when a primary therapist is temporarily absent. The amendment is designed to take effect for all services furnished after the date of the Act's enactment.
