Remittance Balancing
30 - Remittance Balancing
(Rev. 3288, Issued: 07-02-15, Effective: 08-03-15, Implementation: 08-03-15)
For Medicare the principles of remittance balancing are the same for both paper and
electronic remittance formats. Balancing requires that the total paid amount is equal to
the total submitted charges plus or minus payment adjustments for a single ASC X12 835
remittance in accordance with the rules of the standard ASC X12 835 format. Refer to
Front Matter Section 1.10.2.1 for Balancing in the ASC X12 835 version 5010 TR3.
Every HIPAA compliant ASC X12 835 transaction issued by a MAC must comply with
the ASC X12 835 version 5010 TR3 requirements, i.e., these remittances must balance at
the service, claim, and provider levels. The flat files generated by the shared systems
must be balanced at the line, claim, and provider level. As a failsafe measure claim
adjustment reason code121 and PLB reason code 90 may be used at the line, claim, and
provider level respectively to make sure that the ASC X12 835 is balanced. Shared
System generated reports must track the usage of these codes, and A/B MACs and DME
MACs must work closely with the shared system maintainers and CMS to resolve the
issues resulting in out of balance situations.
