Termination-Due Process

(a) Before terminating a contract with a physician or provider, a health maintenance organization shall provide to the physician or provider a written explanation of the reasons for termination.

(b) On request, before the effective date of the termination and within a period not to exceed 60 days, a physician or provider is entitled to a review by an advisory review panel of the health maintenance organization’s proposed termination, except in a case involving:

(1) imminent harm to patient health;

(2) an action by a state medical or dental board, another medical or dental licensing board, or another licensing board or government agency that effectively impairs the physician’s or provider’s ability to practice medicine, dentistry, or another profession; or

(3) fraud or malfeasance.

(c) An advisory review panel must:

(1) be composed of physicians and providers who are appointed to serve on the standing quality assurance committee or utilization review committee of the health maintenance organization; and

(2) include, if available, at least one representative of the physician’s or provider’s specialty or a similar specialty.

(d) The health maintenance organization must consider, but is not bound by, the recommendation of the advisory review panel.

(e) The health maintenance organization on request shall provide to the affected physician or provider a copy of the recommendation of the advisory review panel and the health maintenance organization’s determination.

Anti-retaliation

(f) A health maintenance organization may not terminate participation of a physician or provider solely because the physician or provider informs an enrollee of the full range of physicians and providers available to the enrollee, including out-of-network providers.
