CMS Pub. 100-05, ch. 5, § 50.2.6
Error Resolution
A/B MACs (Part A) and A/B MACs (HHH) are responsible for resolving error conditions
reflected as return codes. These return codes are identified in §50.2.3 above and in the
Medicare Secondary Payment Technical manuals. It is easier to resolve error conditions by
turning on the test switch provided in the software and printing the displays.
After reviewing the displays, if the A/B MAC (Part A) and A/B MAC (HHH) is still unable to
resolve an error condition, it forwards these displays to its shared system’s representative. It
includes any additional documentation that may assist in resolving the error.

Unofficial copy of government-published law, reproduced from official sources with full provenance. Not an official publication; verify against official sources before relying on it in a filing. Records in the 'guidance' corpus, and only that corpus, are sub-regulatory (interpretive guidelines, survey procedures) and are not binding law. Validity bounds follow each jurisdiction's declared temporalBasis.
