(b) For purposes of this section, “plan contract” means every plan contract, except a specialized health care service plan contract, that covers hospital, medical, or surgical expenses.
(c) Nothing in this section shall be construed to prohibit a plan from excluding coverage for dental services provided that any exclusion does not result in any failure to provide medically-necessary basic health care services.
