Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- hot liquid metals X18
7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

About the X12 Code Range
The ICD-10 code X12 category is used to specify injuries resulting from contact with various hot fluids. These codes help document accidents caused by hot liquids or vapors, including burns sustained from hot water, molten substances, or industrial liquids.
The section includes detailed codes for the initial encounter (X12.XXXA), subsequent encounters (X12.XXXD), and sequela (X12.XXXS) related to these injuries. Common terms such as "burn by hot liquid," "accident caused by hot liquid and vapor," and burns involving "hot drinks, fats, cooking oils, molten bitumen, or geothermal hot water" fall under this code set. This makes these codes essential for accurately coding injuries from diverse hot fluid exposures, whether from household accidents like kettle burns or industrial incidents involving molten plastic. The inclusion of sequela codes also addresses ongoing complications such as ulcers caused by thermal injury to the esophagus.
