42 CFR § 410.74 - Physician assistants' services.
(2) The physician assistant -
(i) Meets the qualifications set forth in paragraph (c) of this section;
(ii) Is legally authorized to perform the services in the State in which they are performed;
(iii) Performs services that are not otherwise precluded from coverage because of a statutory exclusion;
(iv) Performs the services in accordance with state law and state scope of practice rules for physician assistants in the state in which the physician assistant's professional services are furnished. Any state laws and scope of practice rules that describe the required practice relationship between physicians and physician assistants, including explicit supervisory or collaborative practice requirements, describe a form of supervision for purposes of section 1861(s)(2)(K)(i) of the Act. For states with no explicit state law and scope of practice rules regarding physician supervision of physician assistant's services, physician supervision is a process in which a physician assistant has a working relationship with one or more physicians to supervise the delivery of their health care services. Such physician supervision is evidenced by documenting at the practice level the physician assistant's scope of practice and the working relationships the physician assistant has with the supervising physician/s when furnishing professional services.
(vi) Performs the services -
(A) In all settings in either rural and urban areas; or
(B) As an assistant at surgery.
(b) Services and supplies furnished incident to a physician assistant's services. Medicare Part B covers services and supplies incident to the services of a physician assistant if the requirements of § 410.26 are met.
(c) Qualifications. For Medicare Part B coverage of his or her services, a physician assistant must meet all of the following conditions:
(1) Have graduated from a physician assistant educational program that is accredited by the Commission on Accreditation of Allied Health Education Programs; or
(2) Have passed the national certification examination that is administered by the National Commission on Certification of Physician Assistants; and
(3) Be licensed by the State to practice as a physician assistant.
(d) Professional services. Physician assistants can be paid for professional services only if the services have been professionally performed by them and no facility or other provider charges for the service or is paid any amount for the furnishing of those professional services.
(2) The services are provided on an assignment-related basis, and the physician assistant may not charge a beneficiary for a service not payable under this provision. If a beneficiary has made payment for a service, the physician assistant must make the appropriate refund to the beneficiary.
(e) Medical record documentation. For physician assistants' services, the physician assistant may review and verify (sign and date), rather than re-document, notes in a patient's medical record made by physicians; residents; nurses; medical, physician assistant, and advanced practice registered nurse students; or other members of the medical team, including, as applicable, notes documenting the physician assistant's presence and participation in the service.
