(1) Except as provided in this section, a health maintenance agreement entered into or renewed after December 31, 1989, shall offer optional coverage for the treatment of temporomandibular joint disorders.
(a) Health maintenance organizations offering medical coverage only may limit benefits in such coverages to medical services related to treatment of temporomandibular joint disorders. No health maintenance organizations offering medical and dental coverage may limit benefits in such coverage to dental services related to treatment of temporomandibular joint disorders. No health maintenance organization offering medical coverage only may define all temporomandibular joint disorders as purely dental in nature.
(b) Health maintenance organizations offering optional temporomandibular joint disorder coverage as provided in this section may, but are not required to, offer lesser or no temporomandibular joint disorder coverage as part of their basic group disability contract.
(c) Benefits and coverage offered under this section may be subject to negotiation to promote broad flexibility in potential benefit coverage. This flexibility shall apply to services to be reimbursed, determination of treatments to be considered medically necessary, systems through which services are to be provided, including referral systems and use of other providers, and related issues.
(2) Unless otherwise directed by law, the insurance commissioner shall adopt rules, to be implemented on January 1, 1993, establishing minimum benefits, terms, definitions, conditions, limitations, and provisions for the use of reasonable deductibles and copayments.
(3) A health maintenance organization need not make the offer of coverage required by this section to an employer or other group that offers to its eligible enrollees a self-insured health plan not subject to mandated benefit statutes under Title 48
RCW that does not provide coverage for temporomandibular joint disorders.
