Final answer:
Medicare Part B does not necessarily require line-of-sight supervision for a PT student. It is applicable to various facilities including outpatient clinics, doctor's offices, and rehabilitation centers.
Step-by-step explanation:
The type of Medicare that does not necessarily require line-of-sight supervision for a PT student is Medicare Part B.
Medicare Part B is an optional insurance system that covers health-care costs outside of hospital stays for physician services, medical tests, and outpatient visits. Unlike Medicare Part A, Part B does not necessarily require line-of-sight supervision for a PT student. This means that PT students can provide certain services under the supervision of a licensed healthcare professional without the need for direct observation.
This exception is applicable to various facilities including outpatient clinics, doctor's offices, and rehabilitation centers.
