A hospital may avail itself of the provisions of this chapter for purposes of determining payment for hospitalization of a medically indigent person only if the hospital has filed a detailed statement of costs with the secretary of social services in the form prescribed by the secretary. The statement of costs shall compute and set forth the ratios of costs to charges for the hospital's fiscal year covered by the statement of costs. The statement of costs shall be filed with the secretary at least annually, unless such period is extended or otherwise provided by the secretary, but a hospital may file a detailed statement of costs or amendments to such a statement once every six months.
