Except as provided in this Part or in Public Health Law article 2 title 11- D, a practitioner authorized to order clinical laboratory services, pharmacy services, radiation therapy services, or X-ray or imaging services may not make a referral for such services to a health care provider authorized to provide such services where such practitioner or immediate family member of such practitioner has a financial relationship with such health care provider. A referral shall not be construed to include an arrangement whereby a treating practitioner makes arrangements with another covering practitioner for the treatment and/or care of the treating practitioner's patients for services routinely provided by the treating practitioner when the treating practitioner is unavailable to treat such patients.
