(Medicare Claims Processing Manual)

Each message on the file is tied to an alphabetic code o n the MSN.  Print no more than three alphabetic codes per claim level and three alphabetic codes per service line.   Messages containing fill- in blanks may be left as blanks for filling in by the system or may be entered into the system with blanks pre -filled to create as many specific messages as there are fill -in situations.  The message numbering in this section does not have to be used in MAC message generating systems.   Certain messages are mandated.  These messages and the situations for which they are mandated are identified in the MSN message file at the hyperlink at the end of this section.  This does not eliminate the need to use other messages required by instructions elsewhere in the manual.   Beneficiary liability Add -on messages should be print ed in addition to denial and reduction messages for charges which the beneficiary is determined not liable.  Liability Add -on messages should print for denials or reductions such as:    Services that are part of another service or bundled code;    Services d etermined not to be medically necessary in situations where the beneficiary was not notified in writing, prior to receipt of the service, that Medicare may not make payment;    Duplicate charges; and    Denials for utilization reasons.   The complete list of MS N messages is only available electronically.
