Interim Cost and Enrollment Reports
20 - Interim Cost and Enrollment Reports
(Rev. 4, 10-01-01)
In addition to the annual budget and enrollment forecast, the cost-based HMO/CMP is
required to submit interim reports and enrollment data on a cumulative quarterly basis.
CMS, in accordance with 42 CFR 417.572(c)(2), may reduce the frequency of the interim
reporting requirements if it is determined that the HMO/CMP has an adequate ongoing
accounting and enrollment data system that furnishes the records needed to verify the
interim per capita rate. Generally, CMS would require, at a minimum, 1 year of operating
experience under a Medicare contract before waiving any quarterly interim cost reporting
requirements. The interim cost and enrollment reports, unless waived, must be submitted
to CMS within 60 days of the end of each HMO/CMP fiscal quarter. The reports may be
used to adjust the interim rate. If the reports are not submitted timely, CMS may adjust
the interim rate based on the best available information. An adjustment to the interim rate
will remain in effect until such time as the required reports are submitted. If there is not
enough data available, interim payments will not be made.
The last interim cost and enrollment report submitted for a specific contract period will
be the basis for an interim settlement with the HMO/CMP. (See section 20.1.2.)
