 (skip to: notes  samples)

Attribute Name	Description	Count (MRSAT.RRF)
ORDER_NO	Order number	79503
EXCLUDES1	A pure excludes. It means "NOT CODED HERE!" Indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. Used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.	5463
EXCLUDES2	Represents "Not included here". Indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When an Excludes2 note appears under a code it is acceptable to use both the code and the excluded code together.	2017
ALT_SORT_CODE	Alt sort code	1020
USE_ADDITIONAL	Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/ manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.	697
CODE_FIRST	Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.	283
CODE_ALSO	Instructs that 2 codes may be required to fully describe a condition but the sequencing of the two codes is discretionary, depending on the severity of the conditions and the reason for the encounter.	146
NOTE	Note	82
MTH_EXCLUDES1	MTH pure excludes.	19
MTH_EXCLUDES2	MTH "Not included here".	5
FROMRSAB	Root source abbreviation for the "from" identifiers of a map set	3
FROMVSAB	Versioned source abbreviation for the "from" identifiers of a map set	3
MAPSETRSAB	Root source abbreviation for a map set	3
MAPSETVERSION	Version of the map set	3
MAPSETVSAB	Versioned source abbreviation for a map set	3
MAPSETXRTARGETID	Map set target identifier used for XR mappings.	3
MTH_MAPFROMCOMPLEXITY	Indicates the complexity of "from" expressions used in a map set	3
MTH_MAPFROMEXHAUSTIVE	Indicates whether or not the "from" source of a map set is completely mapped	3
MTH_MAPSETCOMPLEXITY	Indicates the overall complexity of a map set	3
MTH_MAPTOCOMPLEXITY	Indicates the complexity of "to" expressions in a map set	3
MTH_MAPTOEXHAUSTIVE	Indicates whether or not the "to" source is completely mapped	3
SOS	Scope Statement	3
TORSAB	Root source abbreviation for the "to" identifiers of a map set	3
TOVSAB	Versioned source abbreviation for the "to" identifiers of a map set	3
MTH_CODE_FIRST	MTH Code First note. Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology.	2
