Line Item Detail Billing and Automated Claim Adjustments
50.4 - Line Item Detail Billing and Automated Claim Adjustments
(Rev. 1364, Issued: 11-02-07: Effective: 04-01-08; Implantation: 04-07-08)
The implementation of line item detail billing for ESRD claims effective on April 1, 2007
requires that each service be submitted on a separate line with the appropriate line item
date of service. The Medicare standard systems perform line item date of service
compare for RDFs claims with statement billing periods overlapping the statement billing
period of another processed claim. This prevents monthly claims from receiving
overlapping edits based on the statement billing period dates but rather, only when the
RDF claim has a line item that duplicates another processed claim or falls within the
dates of an inpatient hospital stay. Standard systems reject only those overlapping line
items while any line items not overlapping another claim continue to process for
payment. As a result of this logic, the RDFs no longer have to submit the occurrence
span code 74 on the monthly dialysis claim when an inpatient stay occurred during the
same month.
The initial line item detail billing instruction did not implement a process for rejecting
services on the RDF claim overlapping an inpatient stay when the RDF claim is received
before the inpatient hospital claim. A subsequent instruction implemented for April 1,
2008 requires the Medicare Common Working File (CWF) to create an informational
unsolicited response prompting the standard system to perform an automated adjustment
of the processed 72x claim that contains line item dates of service that are overlapping
dates of an incoming inpatient hospital claim. The admission and discharge dates of an
inpatient stay are not considered overlapping dates and may be payable to the RDF.
