(a) Each subscriber's contract issued after July 1, 1966, by a service corporation constitutes a direct obligation of the participant providers or participant hospitals of the service corporation to render the medical or hospital services, as the case may be, as agreed to be rendered by the participants in the subscriber's contract.

(b) Each subscriber's contract or certificate must in adequate detail set out provisions from which can be readily determined

(1) the services to which the subscriber is entitled from participant providers or participant hospitals, as the case may be;

(2) the benefits, if any, to which the subscriber is entitled on an indemnity basis, consistent with AS 21.87.120, 21.87.130 and the other provisions of this chapter;

(3) the periodic subscription charge, rate, or fee payable by or to the subscriber; or, if not so expressed and the charge, rate, or fee is subject to change, the subscriber's contract must require that not less than 30 days' written notice of the new charge, rate, or fee shall be given to the subscriber or the remitting agent of the subscriber before the change is effective;

(4) the date when the respective services and benefits become available to the subscriber, date of expiration of the contract, and the terms, if any, under which the contract may be continued or renewed;

(5) all other terms and conditions of the agreement between the parties consistent with this chapter;

(6) that the subscriber's contract and riders and endorsements thereon or thereto, together with application therefor, if any, signed by the subscriber, and identification issued to the subscriber, constitutes the entire contract between the parties.

(c) A contract may not restrict the subscriber's right to free choice of provider or hospital, but must restrict benefits to be provided on a service basis to services rendered by participant providers and participant hospitals.

(d) All exceptions and exclusions in the contract shall be printed and otherwise set out as prominently as the services or benefits to which they apply.

(e) This title may not be construed to prohibit a service corporation from issuing contracts to groups of persons under a master contract. In this event, however, each subscriber covered under the master contract shall be issued an individual certificate that shall set out in adequate detail the provisions itemized in (b) of this section.

(f) All proposed forms of subscriber's contracts shall be filed with the director and are subject to the approval of the director under AS 21.87.180.
