(a) The actual cost of hospitalization utilized in any calendar month at the State Medical Center by medical indigents as determined as provided in § 6-64-503 which is in excess of the dollar value at prevailing average per diem cost of one-twelfth (1/12) of the quotas set out in § 6-64-505 shall be charged to the county in which the recipient of the medical service resides or, in case a quota is assigned to the municipality in which the recipient resides, to the municipality.

(b)

(1) No unused quota amounts remaining in any month may thereafter be used as a credit against charges in any other month.

(2) Furthermore, no unused portion of a quota during any month by any county shall be allowed as a credit against any other county that may have exceeded its quota during such month.

(c)

(1) Each thirty (30) days a statement of charges due to the State Medical Center shall be mailed to the county judge or chief administrative officer of the municipality for the net cost of excess services, as defined in subsection (a) of this section, rendered during the calendar month preceding.

(2) Whenever the county or municipality fails to pay to the State Medical Center, within thirty (30) days, the net charges billed to the county or municipality for services in excess of the quotas established in § 6-64-505, the medical center shall make a certification to the Treasurer of State setting forth the names of the county or municipality as the case may be, the amount owed by the county or municipal corporation, and the period during which the unpaid debt shall have accrued.

(3) Upon receipt of the certification, the Treasurer of State shall withhold from such moneys as would otherwise be due such county or municipality from the general revenues of this state the amount needed to liquidate the debt and transfer the amount thereof to the University of Arkansas Medical Center Fund. Any remaining balance of such general revenues which would otherwise have been payable to the county or municipality shall be paid to such county or municipality as in the instance in which no withholding was made.
