N.Y. Pub. Health Law § 4500
The security of the health and welfare of the residents of this state requires, that the utmost attention be given to assure that persons seeking medical care and treatment in this state receive adequate care rendered within the standards of ethics and public policy applicable to all practices of medicine. Medical referral services, organized as profit making enterprises within this state, have been found to be engaged in the practice of medicine, have been sharing fees received for referrals with doctors and hospitals to whom patients are referred, have been otherwise compensating doctors and hospitals for accepting patients referred to them, have been giving medical advice by telephone to persons seeking referrals and have been advertising their services, all in violation of the standards of ethics and public policy applicable to the practice of medicine and which would be violations of standards of professional conduct if the acts were performed by physicians. Such profit making referral services have consistently engaged in practices inimical to the public interest which would be prohibited to physicians and have engaged in relationships with physicians which are in violation of the laws and public policy of this state and which have permitted physicians to benefit indirectly from acts and practices which would be prohibited to them directly. It is hereby declared to be the public policy of this state that the public health, safety and welfare of the citizens of this state require that such profit making medical referral service organizations be declared to be invalid and unlawful in this state.
