(1) From and after July 1, 1990, no group or blanket disability insurance policy shall be issued in Idaho which excludes from coverage services rendered the insured while a resident in an Idaho state institution, provided the services to the insured would be covered by the policy if rendered to him outside an Idaho state institution.
(2)  From and after July 1, 1990, no group or blanket disability insurance policy may contain any provision denying or reducing benefits otherwise provided under the policy for the reason that the person insured is receiving health or mental health care or developmental services provided by the department of health and welfare, whether or not the department of health and welfare bases its charges for such services on the recipient’s ability to pay. Provided, nothing in this section shall prevent the issuance of a policy which excludes or reduces benefits where the charge level or amount of the charge levied by a governmental entity for such services would vary or be affected in any way by the existence of insurance coverage.
