Final answer:
The two requirements that must be met for therapy services to be reimbursed under Medicare are the prescription requirement and medical necessity.
Step-by-step explanation:
For therapy services to be reimbursed under either Medicare Part A or B, two requirements must be met: prescription requirement and medical necessity. This means that a physician or other authorized health care provider must prescribe the therapy, deeming it necessary for the treatment of an individual's health condition. Additionally, the therapy services must be considered medically necessary, which involves a determination that the services are proper and needed for the diagnosis or treatment of a medical condition, that they meet the standards of good medical practice, and are not primarily for the convenience of the patient or doctor.
