The state agency shall establish on a statewide basis a system for the centralized disbursement of medical assistance payments to vendors.
An account is established in the state treasury from which medical assistance payments to vendors shall be made.

The state agency shall prescribe and furnish vendors suitable forms for submitting claims under the medical assistance program.
The state agency in establishing a statewide system of centralized disbursement of medical assistance payments shall comply with federal requirements in order to receive the maximum amount of federal funds which are available for the purpose, together with such additional federal funds which may be made available for the operation of a centralized system of disbursement of medical assistance payments to vendors.
If required by federal law or rules promulgated thereunder, or by authorized rule of the state agency, each county shall pay to the commissioner of management and budget the portion of medical assistance paid by the state for which it is responsible.
The county shall advance medical assistance costs not met by federal funds, based upon estimates submitted by the state agency to the county agency, stating the estimated expenditures for the succeeding month. Upon the direction of the county agency, payment shall be made monthly by the county to the state for the estimated expenditures for each month. Adjustment of any overestimate or underestimate based on actual expenditures shall be made by the state agency by adjusting the estimate for any succeeding month.
Payment to counties under this subdivision is subject to the provisions of section 256.017.
The commissioners of human services and administration may contract with any agency of government or any corporation for providing all or a portion of the services for carrying out the provisions of this section. Local welfare agencies may pay vendors of transportation for nonemergency medical care when so authorized by rule of the commissioner of human services.
