30.5 - Notification to Providers Regarding Interest Assessment
(Rev. 41, 04-30-04)
A. Cost Report Reminder Letters
The FI is required to issue reminder letters to a provider of the time limitation for filing the cost report when
the institutional provider fails to file by the last day of the fourth month following the end of the cost report
period. In addition to the requirements outlined in Chapter 3, §30 and Chapter 4, §20 the FI must include
the following in a cost report reminder letter:
1.
Late Filing Interest- If a cost report is not filed on time and indicates an amount is due CMS,
or if it is subsequently determined that an additional overpayment exists, such as when an NPR is issued,
interest will be assessed on the overpayment from the due date of the cost report to the date the cost report
was filed. This interest assessment is made regardless of whether the overpayment is liquidated within 30
days.
2.
Assessed Interest- If a cost report is filed on time and indicates an amount is due CMS,
interest will accrue on that overpayment from the date the cost report is due, unless full payment
accompanies the report or the provider and the contractor agree in writing, in advance, to recoup the amount
of the overpayment from interim payments over the next 30-day period.
B. Notice of Program Reimbursement (NPR)
In addition to the requirements outlined in audit instructions, all NPRs issued after September 3, 1982, must
include the following:
"In accordance with the procedures of 42 CFR 405.378ff interest will be assessed on the
amount due CMS unless full payment is made within 30 days from the date of the Notice.
Interest will be assessed for each full 30-day period that payment is delayed."
C. Overpayment Demand Letters
In addition to the requirements of Chapter 4, §20 and §90 the FI and Carrier’s written demand for repayment
must contain a notice that in accordance with 42 CFR 405.378, interest shall be assessed on all
overpayments at the prevailing rate specified by the Secretary of the Treasury unless repayment is made
within 30 days. Interest shall be assessed for each full 30-day period that payment is delayed and shall
accrue from the date of the final determination. The demand letter shall include the appropriate interest rate
that will be assessed if payment in full is not received within 30 days.
