Medicare Financial Management Manual (Pub. 100-06), Ch. 3 § 60
Interim Rate Adjustments and Periodic Interim Payment Adjustments – FI only
60 - Interim Rate Adjustments and Periodic Interim Payment Adjustments – FI only
(Rev. 29, 01-02-04)
The interest provisions of Chapter 4, §30 do not apply to FI overpayments or underpayments determined
as a result of interim rate and periodic interim payment (PIP) adjustments or utilization reviews. If
necessary, an interim rate or periodic interim payment adjustment shall occur prior to the end of the cost
reporting year. When this occurs, the interim rate or periodic interim rate is adjusted for the remainder
of the cost reporting year in order to have aggregate payments approximate total allowable costs. This
adjustment is based on any overpayment or underpayment determined as a result of the interim review.
Since payments are adjusted, this overpayment or underpayment should not exist at the end of the cost
reporting year.
If the adjustment of the payments would provide a hardship to the provider and an extended repayment
plan is requested instead, interest shall accrue on the overpayment. The interest rate charged shall be the
rate in effect on the date the notice of payment adjustment was sent to the provider unless a specific
instruction is issued as in the case of Interim Payment System (IPS) recoveries for FY 1998 & 1999
(Transmittal A-99-47). This is true for any entity that is reimbursed in such a way that interim rate
adjustments and/or periodic interim payment adjustments are required.
If the review is completed after the end of the cost reporting year or after the cost report is filed,
adjustments to the interim or periodic rate are not possible. In this case any determined overpayment or
underpayment shall be considered in conjunction with the final settlement. By taking the overpayment
or underpayment into consideration with the tentative or final settlement the FI will issue a tentative
settlement payment, tentative settlement demand letter, or Notice of Program Reimbursement. When a
demand letter or Notice of Program Reimbursement is issued, interest will be assessed if necessary, and
the provider will be notified of it’s appeal rights. Any determined overpayment shall then be recouped.
