ADDITIONAL REIMBURSEMENT FOLLOWING PROVIDER COMPLAINT

(a) If, after an investigation, the commission determines that a Medicaid managed care organization owes additional reimbursement to a provider, the organization shall, not later than the 90th day after the date the provider filed the complaint, pay the additional reimbursement or provide to the provider a reimbursement payment plan under which the organization must pay the entire amount of the additional reimbursement not later than the 120th day after the date the provider filed the complaint. (b) The commission may require a Medicaid managed care organization to pay interest on any amount of the additional reimbursement that is not paid on or before the 90th day after the date the provider to whom the amount is owed filed the complaint. If the commission requires the organization to pay interest, interest accrues at a rate of 18 percent simple interest per year on the unpaid amount beginning on the 90th day after the date the provider to whom the amount is owed filed the complaint and accrues until the date the organization pays the entire reimbursement amount.
