The costs incurred by the treatment facility and other providers of services to diagnose or treat the carrier for tuberculosis must be borne by the carrier, the carrier's health plan, or public programs. During the period of insurance coverage, a health plan may direct the implementation of the care required by the health order or court order and shall pay at the contracted rate of payment, which shall be considered payment in full. Inpatient hospital services required by the health order or court order and covered by medical assistance or general assistance medical care are not billable to any other governmental entity. If the carrier cannot pay for treatment, and the carrier does not have public or private health insurance coverage, the carrier shall apply for financial assistance with the aid of the county. For persons not otherwise eligible for public assistance, the commissioner of human services shall determine what, if any, costs the carrier shall pay. The commissioner of human services shall make payments at the general assistance medical care rate, which will be considered payment in full.
