(1) The agency reconciles each interim supplemental payment for GEMT to the provider's filed cost report for the service year in which interim supplemental payments are made.

(2) The agency compares the total medicaid-allowable costs to the interim supplemental payments paid to the participating providers as documented in the agency's claim system, resulting in cost reconciliation.

(3) The agency performs cost settlements based on the final Centers for Medicare and Medicaid Services (CMS)-approved cost report schedules for all participating providers.

(a) The agency:

(i) Recovers from the participating provider the federal payments that exceed the participating provider's cost per qualifying transport; or

(ii) Pays the participating provider if the cost per transport exceeds the interim supplemental payment amount.

(b) If a participating provider disputes the reimbursement rate before there is an overpayment, the provider may appeal under WAC 182-502-0220.

(c) If a participating provider disputes the agency's determination that the participating provider has been overpaid, the participating provider may request a hearing under WAC 182-502-0230.

(4) The agency reports to the CMS any difference between the payments of federal funds made to the participating providers and the federal share of the qualifying expenditures and returns excess funds to CMS.

(5) Each participating provider must agree to reimburse the agency for the costs associated with administering the GEMT program. The costs are collected during the final reconciliation and settlement process and cannot be included as an expense in the participating provider's cost report.
