Cal. Gov. Code § 37615.6
Notwithstanding the provisions of the Medical Practice Act, the board of trustees may contract with physicians and surgeons, health care provider groups, and nonprofit corporations for the rendering of professional health services on a basis that does not result in any profit or gain to the municipal hospital from the services so rendered and that allows the board of trustees to ensure that fees and charges, if any, are reasonable, fair, and consistent with the basic commitment of the municipal hospital to provide adequate health care to all residents within its service area. However, nothing in this section shall authorize activities that corporations and other legal entities are prohibited from conducting by Section 2400 of the Business and Professions Code.
