CMS Pub. 100-09, ch. 1, § 10
Introduction
This chapter contains general instructions and requirements for Medicare carriers,
including DMERCs and intermediaries for processing correspondence. Normally, the
term “contractor” is used in this manual to mean any or all of these. If an instruction
should apply to only one type of contractor, this will be specified.
Instructions for preparation of the MSN are found in Chapter 21 of the Medicare Claims
Processing Manual. Similarly, the Medicare Secondary Payer (MSP) correspondence
instructions are found in the MSP Manual.
This manual does not apply to End Stage Renal Disease (ESRD) Network Organizations
or Quality Improvement Organization (QIO). They have separate instructions in the
ESRD Network Organizations Manual and QIO Manual, respectively.

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.
