Term Type | Description | Origin |
---|---|---|
AB | Abbreviation (Short description) | CODE = icd10cm_order_<YYYY>.txt (character
positions 7-13) STR = icd10cm_order_<YYYY>.txt (character positions 17-76) SDUI = same as CODE SUPPRESS = "Y" |
ET | Entry Term | CODE: value of "<name>" tag in
icd10cm_tabular_<YYYY>.xml STR: value of "<includes>" or "<inclusionTerm>" tag in icd10cm_tabular_<YYYY>.xml SDUI: same as CODE SUPPRESS = "Y" |
HT | Hierarchical Term | CODE:
SDUI: same as CODE SUPPRESS = "N" Note: Chapters, Sections, and all "non-leaf" nodes are assigned TTY = "HT." In icd10cm_order_<YYYY>.txt, a value of "0" in character position 15 indicates that the code is not valid for submission on a UB04. |
PT | Preferred Term | CODE: Value of "<name>" tag For 7th character extensions: the "<sevenChrDef extension>" char is appended to the subcategory name value STR: value of "<desc>" tag in icd10cm_tabular_<YYYY>.xml For 7th character extensions: The "<sevenChrDef>" value is appended to the desc value SDUI: same as CODE SUPPRESS = "N" Note: All "leaf" nodes are assigned TTY = "PT." In icd10cm_order_<YYYY>.txt, a value of "1" in character position 15 indicates that the code is valid for submission on a UB04. |
Most attributes are extracted from "<note>" tags in icd10cm_tabular_<YYYY>.xml.
ATN | Note Type | Description |
---|---|---|
CODE_ALSO | codeAlso | 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. |
CODE_FIRST | codeFirst | 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. |
EXCLUDES1 | 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. |
EXCLUDES2 | 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. |
NOTE | notes | |
ORDER_NO | N/A | Order number (icd10cm_order_<YYYY>.txt characters 1-5) |
USE_ADDITIONAL | useAdditionalCode | 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. |
