CMS Pub. 100-06, ch. 6, § 120.1
Classification of Claims for Counting
All claims data entered on page one of the performance report must represent counts of claims
(real and replicate) as defined in the Medicare Claims Processing, Chapter 1, General Billing
Requirements. The carrier includes in column (i) the following types of claims: CMS-1500s,
CMS-1490s, and CMS-1491s. Of these claims forms, it reports the assigned in column (ii) and the
unassigned in column (iii).
It includes any claims where processing has been suspended due to CMS directives since they are
still part of its claims workload.
NOTE: It does not count assigned claims received from physicians/suppliers if they are
incomplete, incorrect, or inconsistent and consequently returned for clarification. It does not have
to control such claims.
Throughout its process, it includes the date material is received on all claims (real and replicate).
It shows identifying numbers or codes on all replicate claims through the processing system so that
they can be counted and reported separately in Part A.
The carrier reports claims as received in the month the claim is received in its mailroom with the
following exceptions:
• Additional real claims resulting from a split; and
• Claims identified as replicates.
Split and replicate claims, although carrying the dates the materials were originally received, are to
be counted as receipts for the month in which they are recognized by the carrier's system as
created (i.e., split or identified as replicate) for purposes of this report.
EXAMPLE: The carrier splits a claim received in the reporting month into two claims because the
total number of line items exceeds its system's line item limitation. If it can recognize this split
when it occurs, it reports two claims in "Total Claims Received During Month" and in "Net
Number of Claims Received" (lines 4 and 6, respectively) in Part A of the report. It reports both
claims in Part A. After processing the split (replicate) claim, it reports it in Part A under
"Replicate Claims Processed" (line 16), as well as under "Total Claims Processed" (line 15). If its
system does not indicate when the split occurs, it counts the new claim as a receipt for the month
in which the system allows it to be recognized, although the date claims materials were originally
received must be carried forward and remain unchanged.
The carrier counts claims received near the end of the reporting month but placed under computer
control in the following month as received in the reporting month. It obtains this count by a
physical inventory or by computer count.
