CMS Pub. 100-06, ch. 6, § 130.2
Part A - Monthly Workload Operations
This part of the report presents data on carrier claims processing activity during the reporting
period. Counts of claims (real and replicate) processed, total claims (real and replicate) pending,
or pending from prior months must reflect the actual status of claims (real or replicate) workloads
as of the last day of the reporting calendar month. Data shown must be based on reliable counts of
all claims (real or replicate) processing activity and the entire "in-house" pending workload. This
data may not be derived from estimates.
If a single claim is split into two or more real claims, or into one real claim and one or more
replicate claims, the carrier considers each split (real and replicate) as a separate, distinct claim for
purposes of counting claims. The original real claim is a receipt for the month in which it was
received. It counts a claim split from the original, or identified as a replicate, as a receipt for the
month in which it is actually created or in which its system recognizes it as a separate claim. To
determine the age of pending claims, the carrier considers the receipt date as the date the original
claim was received and not the date it was split from another claim.
It reports, in Part A, only data relating to initial claims (real and replicate) actions. It does not
report data on requests for, or dispositions of, reviews, hearings, or reopenings of initial claim
actions.
Opening Pending
Line 1. Claims Pending End of Last Month - The system will pre-fill the number
pending from line 17 on the previous month's report.
Line 2. Adjustments - If it is necessary to revise the pending figure for the close of
the previous month, the carrier reports the adjustment, preceded by a minus
sign for negative adjustments, as appropriate. Adjustments normally result
from:
• Private claims incorrectly counted as Medicare claims;
• Beneficiary inquiries or other correspondence incorrectly counted
as Medicare claims; and
• Claims consisting of one or more continuation forms incorrectly
counted as more than one Medicare claim.
The carrier reports claims received near the end of the reporting month, and
placed under computer control sometime after the reporting month, as
claims received in the reporting month. It does not count them as claims
received in the following month. If some claims have not been counted in
the proper month's receipts, it counts them as adjustments to the opening
pending in the subsequent month.
Line 3. Adjusted Opening Pending - The system will sum line 1 + line 2 to
calculate the adjusted opening pending.
Receipts
Line 4. Total Claims Received During Month - The carrier reports all real claims
received during the month and all split and replicate claims generated
(recognized) during the month. (See the Medicare Claims Processing
Manual for a discussion of what constitutes a claim.) Claims received
include all claims received in its mailroom during the reporting month even
though some of them were placed under computer control in the following
month. (See §120.1 for counting receipts.)
The carrier counts claims submitted electronically after they have passed its
consistency edits. Prior to that time, it may return these bills or the entire
tape (where magnetic tape is the medium of submission), as necessary,
without counting them as received. However, once the claims or tapes
have passed consistency edits and are counted as received, it uses the actual
receipt date, not the date the edits are passed, in calculating pending and
processing times.
Line 5. Transferred to Other Carriers - The carrier reports the number of claims
received, but transferred to other carriers or Part A intermediaries, during
the month because the claimant submitted the claim to the wrong
contractor. It includes claims transferred in their entirety or split off from
other claims because they contained services from physicians/suppliers
outside of their carrier jurisdiction.
Line 6. Net Number of Claims Received - The carrier shows the net number of
claims (real and replicate) received after subtracting those transferred.
Line 7. Electronic Media Claims Received - The carrier reports the net number of
claims included in line 6 which were received in paperless form via
electronic media from providers or their billing agencies and read directly
into its claims processing system. It does not count on this line claims that
it received in hardcopy and entered using an Optical Character Recognition
(OCR) device. It does not count any claims received in hardcopy and
transformed into electronic media by any entity working for it directly or
under subcontract.
It counts claims which are split automatically by computer, without manual
intervention, as electronic media claims. This includes "required" splits
only. (See the Medicare Claims Processing Manual. It excludes replicate
claims).
Claims Processed
Line 8. Total CWF Claims - The carrier reports the number of initial claims
(described in lines 9, 10 and 11 below) processed through Common
Working File (CWF) and posted to CWF history. It does not include
claims sent to CWF and rejected, unless they were resubmitted and posted
to CWF history in the reporting month. The counts entered in lines 9, 10
and 11 are exclusive of each other and represent the total number of CWF
claims (real or replicate) processed during the month. On page 1, it reports
these claims in the month it move the claim to a processed location in its
system after receipt of the host's response to pay, apply entirely toward the
deductible or deny in full. For pages 2-9, it reports these claims as
processed in the month during which the scheduled payment date falls,
which may be in a subsequent reporting period.
Line 9. Claims Paid - The carrier reports the number of initial CWF claims (real or
replicate) that it approved for payment and for which the CWF host
responded by accepting its determination during the month. It reports only
claims which are completely processed. If payment is made on part of a
claim and the remainder of the claim requires no payment or is denied for
any reason, it reports the claim as paid. It reports claims that have been
fully adjudicated, with a response having been received from the CWF
host, and that are being held only due to the payment floor.
Line 10. Claims Applied Towards Deductible - The carrier reports the number of
CWF claims (real or replicate) for which no payment was made because the
deductible had not been met. It includes claims for which all charges were
applied toward the deductible, as well as those for which some charges
were denied.
Line 11 Claims Denied - The carrier reports the number of CWF claims (real or
replicate) for which all services were denied because, for example, the
beneficiary was not eligible for Part B benefits, the filing limitation was
exceeded, or services were not covered.
Line 12. Total Non-CWF Claims - The carrier reports the number of initial claims
(real or replicate) processed outside CWF. Non-CWF claims are those
either rejected by or not submitted to CWF which it finally adjudicates
outside of CWF and are, therefore, not posted to its history in the reporting
month. It reports these claims as non-CWF, even if it plans to submit an
informational record in the future. Also, it reports these claims in the month
in which it made the determination as to their final disposition.
Line 13. Claims Approved - Of those claims reported on line 12 as not processed
through CWF, the carrier reports the number approved for payment or with
all charges applied toward the deductible.
Line 14. Claims Denied - Of those claims reported on line 12, the carrier reports the
number on which all services were denied.
Line 15. Total Claims Processed - The carrier reports the sum of lines 8 and 12.
Line 16. Replicate Claims Processed - The carrier reports the number of replicate
claims included under Total Claims Processed, line 15, column (1).
Replicate claims are those claims split off from original (real) claim.
Replicate claims are generally created because of computer line item
limitations, the carrier is making partial payments, or it is carving out
individual specialty types of services. (See the Medicare Claims
Processing Manual, Publication 100-04, Chapter 1, Section 70.2.).
Closing Pending
Line 17. Claims Pending at End of Month - The system calculates the number of
bills pending at the end of the month by adding line 3 (adjusted opening
pending) to line 6 (net receipts) and subtracting line 15 (total processed). It
does not report as pending those bills that the carrier has moved to a
processed location after being accepted by the host and are holding only
due to the payment floor. It reports such bills as processed on line 17.
Distribution by Days Elapsed Since Receipt
Line 18. 1-15 Days - The carrier reports the number of claims, by type, included in
line 17 which are 1-15 days old.
Line 19. 16-30 Days - The carrier reports the number of claims, by type, included in
line 17 which are 16-30 days old.
Line 20. 31-60 Days - The carrier reports the number of claims, by type, included in
line 17 which are 31-60 days old.
Line 21. 61-90 Days - The carrier reports the number of claims, by type, included in
line 17 which are 61-90 days old.
Line 22. Over 90 Days - The carrier reports the number of claims, by type, included
in line 17 which are over 90 days old.
Claim Investigations
Line 23. Number of Claims Investigated During Month - The carrier reports the
number of claims (real and replicate) that required contact during the
month by telephone, correspondence, or automatic inquiry with physician,
beneficiary, supplier, or social security office, or other entities outside the
carrier for missing, incorrect, or inconsistent information. It counts only
the number of claims investigated, not the number of contacts made.
