(1) The purpose of this regulation is to effectuate the provisions of RCW 48.44.325 by establishing definitions for the exceptions to coverage for mammograms. This regulation shall apply to every group and individual health care service contract which is delivered or issued for delivery or renewed in this state on or after September 1, 1992, that provides for hospital or medical care.

(2) For the purposes of RCW 48.44.325 and this regulation, supplemental contracts covering specified disease shall be defined to mean and include only those contracts which provide benefits to a member only in the event that the member contracts the disease or diseases specifically named in the contract. Also for the purposes of RCW 48.44.325 and this regulation, supplemental contracts covering limited benefits shall be defined to mean and include only those contracts providing only one of the following benefits: Hospital indemnity, accident only coverage, dental care, vision care, mental health care, chemical dependency care, pharmaceutical care, and podiatric care.

(3) Coverage of mammograms may be subject to standard contract provisions applicable to other diagnostic X-ray benefits such as deductible or copayment provisions.

(4) For purposes of RCW 48.44.325 and this regulation, a contract is "renewed" when it is continued beyond the earliest date, after September 1, 1992, upon which, at the health care service contractor's sole option:

(a) The contract's termination could have been effectuated, for other than nonpayment of premium; or

(b) The contract could have been amended to add the mammogram coverage, with, if justified, an appropriate rate increase for any increased cost in providing mammogram coverage under the contract.

The failure of the health care service contractor to take any such steps does not prevent the contract from being "renewed." The intent of this section is to bring the mammogram coverage under the maximum number of contracts possible at the earliest possible time, by permitting the health care service contractor to exclude such coverage from only those contracts as to which there exists a right of renewal on the part of the contractholder without any change in any provision of the contract.
