Overview of Pub. 100-05, the MSP Manual
In addition to the General MSP Overview content provided within this chapter,
subsequent chapters of the MSP Manual are available for access at
https://www.cms.gov/Regulations-and-Guidance/Guidance/Manuals/Internet-Only-
Manuals-IOMs-Items/CMS019017. These chapters offer a variety of information
ranging from general MSP provisions and the relationship to other laws to specific
guidance concerning MSP prepayment processing requirements, MSP Recovery
activities, and the MSP Common Working File (CWF) process.
The MSP Manual also includes a chapter outlining information that should be
collected from beneficiaries, instances where MSP billing should be applied,
and the requirements among providers, physicians, or other suppliers. The
Electronic Correspondence Referral System (ECRS) User Guide and ECRS
Quick Reference Card are MSP Manual chapters as well, intended to provide
technical guidance to A/B MACs, DME MACs, and CMS regional office (RO)
staff attempting to transmit change requests to existing CWF MSP
information or submit MSP coverage inquiries.

The link goes to the issuing authority’s own document — the one we read to produce this record. Where a source publishes whole titles rather than sections, your browser may need a moment to jump to the provision.
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.
