Executing and Testing MSPPAY Software
A/B MACs (Part B) and DME MACs receive the MSP software through their standard
system along with the Medicare Secondary Payment Technical Manual documenting, and
describing the execution of the MSPPAY Module(s). The input data elements and output
data elements required are referenced in these manuals. The Medicare Integrated Systems
Testing (MIST) contractor is responsible for testing and verifying the accuracy of the
MSPPAY software when updates are implemented. A/B MACs (Part B) and DME MACs
also test the MSPPAY software independently and review the results.

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.
