Time Value of Money
10.7.2.3 - Time Value of Money
(Rev. 2242, Issued: 06-17-11, Effective: 07-01-11, Implementation: 07-01-11)
Effective for hospital outpatient services furnished in the first cost reporting period on or
after January 1, 2009, at the time of any reconciliation under §10.7.2.2, OPPS outlier
payment may be adjusted to account for the time value of money of any adjustments to
OPPS outlier payments as a result of reconciliation. As described in 42 CFR
419.43(d)(6)(ii), the time value of money is applied from the midpoint of the hospital or
CMHC’s cost reporting period being settled to the date on which the CMS Central Office
receives notification from the Medicare contractor that reconciliation should be
performed.
If a hospital or CMHC’s OPPS outlier payments have met the criteria for reconciliation,
CMS will calculate the aggregate adjustment using the instructions below concerning
reprocessing claims and determine the additional amount attributable to the time value of
money of that adjustment. The index that is used to calculate the time value of money is
the monthly rate of return that the Medicare trust fund earns. This index can be found at
http://www.ssa.gov/OACT/ProgData/newIssueRates.html.
The following formula is used to calculate the rate of the time value of money:
(Rate from Web site as of the midpoint of the cost report being settled / 365) * # of
days from that midpoint until date of reconciliation. NOTE: The time value of
money can be a positive or negative amount depending if the provider is owed money
by CMS or if the provider owes money to CMS.
For purposes of calculating the time value of money, the “date of reconciliation” is the
day on which the CMS Central Office receives notification. This "date of reconciliation"
is based solely on the date CMS Central Office receives notification and not on the date
that reconciliation is approved by the CMS Central and Regional Offices. This date is
either the postmark from the written notification sent to the CMS Central Office via mail
by the Medicare contractor, or the date an email was received from the Medicare
contractor by the CMS Central Office, whichever is first.
The following is an example of the procedures for reconciliation and computation of the
adjustment to account for the time value of money:
EXAMPLE:
Cost reporting period: 01/01/2009 - 12/31/2009
Midpoint of cost reporting period: 07/01/2009
Date of reconciliation: 12/31/2010
Number of days from midpoint until date of reconciliation: 548
Rate from Social Security Web site: 4.625%
Overall ancillary CCR used to pay actual original claims in cost reporting period:
0.40 (This CCR could be from the tentatively settled 2006 or 2007 cost report.)
Final settled operating CCR from 01/01/2009 - 12/31/2009 cost report: 0.50
Total OPPS outlier payout in 01/01/2009 - 12/31/2009 cost reporting period:
$600,000
Because the CCR fluctuated from 0.40 at the time the claims were originally paid to 0.50
at the time of final settlement and the provider has an OPPS outlier payout greater than
$500,000, the criteria have been met to trigger reconciliation. The Medicare contractor
notifies the CMS Central and Regional Offices.
The Medicare contractor reprices the claims in accordance with the process in §10.7.2.4
below. The repricing indicates the revised outlier payments are $700,000.
Using the values above, the rate that is used for the time value of money is determined:
(4.625 / 365) * 548 = 6.9438%
Based on the claims reconciled, the provider is owed $100,000 ($700,000 - $600,000) for
the reconciled amount and $6,943.80 for the time value of money.
