A. No health care plan shall enter into any contract with a subscriber unless it has first filed with the superintendent a full schedule of premium rates to be paid by the subscribers. The superintendent shall notify the health care plan of his approval or disapproval of such rates within fifteen (15) days after the filing thereof, or within thirty (30) days after such filing if he shall so extend the time, and if the superintendent fails to act within such period, the rates shall be deemed approved.

B. At the time the health care plan files such rates with the superintendent, it shall also file a full schedule of all health care expense payments to be made under the contracts.

C. The superintendent may disapprove any such rate found by him to be excessive, inadequate or unfairly discriminatory, considering the health care expense payments to be made.
