Section 411.37 - Amount of Medicare recovery when a primary payment is made as a result of a judgment or settlement(a)Recovery against the party that received payment - (1)General rule. Medicare reduces its recovery to take account of the cost of procuring the judgment or settlement, as provided in this section, if- (i) Procurement costs are incurred because the claim is disputed; and(ii) Those costs are borne by the party against which CMS seeks to recover.(2)Special rule. If CMS must file suit because the party that received payment opposes CMS's recovery, the recovery amount is as set forth in paragraph (e) of this section.(b)Recovery against the primary payer. If CMS seeks recovery from the primary payer, in accordance with §411.24(i), the recovery amount will be no greater than the amount determined under paragraph (c) or (d) or (e) of this section.(c)Medicare payments are less than the judgment or settlement amount. If Medicare payments are less than the judgment or settlement amount, the recovery is computed as follows: (1) Determine the ratio of the procurement costs to the total judgment or settlement payment.(2) Apply the ratio to the Medicare payment. The product is the Medicare share of procurement costs.(3) Subtract the Medicare share of procurement costs from the Medicare payments. The remainder is the Medicare recovery amount.(d)Medicare payments equal or exceed the judgment or settlement amount. If Medicare payments equal or exceed the judgment or settlement amount, the recovery amount is the total judgment or settlement payment minus the total procurement costs.(e)CMS incurs procurement costs because of opposition to its recovery. If CMS must bring suit against the party that received payment because that party opposes CMS's recovery, the recovery amount is the lower of the following: (2) The total judgment or settlement amount, minus the party's total procurement cost.
