RTM codes are classified as General Medicine services. Physicians and eligible qualified healthcare professionals (including but not limited to therapists, physiatrists, nurse practitioners, and other practitioners with Medicare billing privileges) are permitted to bill using the RTM codes. Where the practitioner’s Medicare benefit does not include services furnished incident to their professional services, the items and services described by these codes must be furnished directly by the billing practitioner or, in the case of a physical therapist or occupational therapist, by a therapy assistant under the physical therapist’s or occupational therapist’s supervision.
