Section 450.259 - Overpayments Attributable to Rate Adjustments(A) Whenever an overpayment occurs due to a rate adjustment that is established by the MassHealth agency in accordance with applicable law, the MassHealth agency notifies the provider in writing by issuing a remittance advice identifying the impact of the rate adjustment on all previously paid claims and stating the amount of the overpayment.(B) A provider must pay to the MassHealth agency the full amount of any overpayment attributable to a rate adjustment. The applicable recoupment account will be systematically established against all future payments until the full amount is repaid, unless the provider enters into a payment arrangement with the MassHealth agency under 130 CMR 450.260(H).(C) If a provider disputes the MassHealth agency's computation of an overpayment attributable to a rate adjustment, the provider must submit proposed corrections, including a detailed explanation, in writing to the MassHealth agency within 30 calendar days after the date of issuance of the remittance advice under 130 CMR 450.259(A). The fact that any rate adjustment is under appeal is not considered a factor in determining the amount of liability. The fact that a provider has submitted proposed corrections to the MassHealth agency does not delay or suspend the provider's payment obligations set forth under 130 CMR 450.259(B).(D) If proposed corrections are timely submitted in accordance with 130 CMR 450.259(C), the MassHealth agency reviews the proposed corrections and notifies the provider of its decision within 30 calendar days of receipt of the provider's corrections. If the MassHealth agency determines that corrections are required, the MassHealth agency makes any appropriate payment adjustments reflecting the corrections.(E) A provider must pay the MassHealth agency the full amount of the overpayment stated in a remittance advice under 130 CMR 450.259(A), regardless of any pending appeal, action, or other proceeding contesting the overpayment, including but not limited to, any appeal, action, or other proceeding contesting any rate on which the overpayment is computed. If required by a final disposition of any such appeal, action, or proceeding, the MassHealth agency issues a revised remittance advice and makes any appropriate payment adjustments to effect the final disposition.Amended by Mass Register Issue 1341, eff. 6/16/2017.Amended by Mass Register Issue S1345, eff. 6/16/2017.
