Medicare Secondary Payer Manual (Pub. 100-05), Ch. 7 § 70.13
Intra-governmental Payment and Collection System
70.13 – Intra-governmental Payment and Collection System
(Rev. 12438; Issued: 01-04-24; Effective: 02-06-24; Implementation: 02-06-24)
The collection report generated from the IPAC system includes a breakout of principal and interest collected
on individual debts; however, the report does not show the outstanding balance and the status of the debt
after the collection. Due to system limitations, interest on the CMS debts that have been referred to Treasury
and its PCAs does not continue to accrue on Treasury/PCA records during the entire collection process.
Therefore, the amount of interest collected by Treasury or its PCAs may not equal the amount of interest
shown as accrued by the MSP Contractors.
