WAC 182-502-0130. Interest penalties—Providers

(1) Providers who are enrolled as contractors with the medicaid agency's medical care programs may be assessed interest on excess benefits or other inappropriate payments. Nursing home providers are governed by WAC 388-96-310 and are not subject to this section. (2) The agency assesses interest when: (a) The excess benefits or other inappropriate payments were not the result of agency error; and (b) A provider is found liable for receipt of excess benefits or other payments under RCW 74.09.220 ; or (c) A provider is notified by the agency that repayment of excess benefits or other payments is due under RCW 74.09.220 . (3) The agency assesses interest at the rate of one percent for each month the overpayment is not satisfied. Daily interest calculations and assessments are made for partial months. (4) Interest is calculated beginning from the date the agency receives payment from the provider. Interest ceases to be calculated and collected from the provider once the overpayment amount is received by the agency. (5) The agency calculates interest and amounts, which are identified on all agency collection notices and statements.
