In order to promote and preserve the health of the people of this state, there is established a Hospital Care for the Indigent Program to be administered by the Department of Human Resources. The purpose of this program is to assist counties in the purchase of hospital care for persons who are ill or injured and who can be helped by treatment in a hospital but are financially unable to meet the full cost of hospital care from their own resources or from the resources of those upon whom they are legally dependent. The purchase of such hospital care shall be limited to the nonprofit basic cost of hospital care needed for the treatment of the ill or injured, as deemed necessary and ordered by the physician in charge of the case in accordance with this article and the rules, regulations, and standards adopted and promulgated pursuant to this article.
