CPT codes 95249 and 95250 do not have any physician work RVUs (Relative Value Units); therefore, the associated services can be performed by a trained RN, PharmD/RPh, RD, CDE or MA (if within their scope of practice) and billed by the supervising physician advanced practitioner or hospital outpatient department. However, only providers such as Physician (MD), Nurse Practitioner (NP), Physician Assistant (PA) or Clinical Nurse Specialist (CNS) can perform and bill for services associated with CPT code 95251.
