Contact with hot engines, machinery and tools (X17) ICD-10-CM
The X17 code range covers contact with hot engines, machinery and tools with 4 ICD-10-CM diagnosis codes. 3 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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.
- contact with hot heating appliances, radiators and pipes X16
- contact with hot household appliances X15
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 X17 Code Range
The ICD-10 code X17 covers injuries caused by contact with hot engines, machinery, and tools. These codes are specifically used to classify burns resulting from accidental exposure to hot mechanical parts or tools.
The code X17 is the general category for contact with such heat sources, while X17.XXXA, X17.XXXD, and X17.XXXS specify the encounter type: initial, subsequent, or sequela (aftereffects). These codes capture incidents like being accidentally burned by machinery, contact with hot parts of a vehicle engine, or burns caused by heat energy released from machines. Using these codes helps medical coders accurately document the cause of injury related to heat from engines and tools. The inclusion of synonyms such as "accidentally burned by machinery" and "burning due to contact with hot machinery and tools" assists in linking common injury descriptions to the appropriate ICD-10 code for these specific situations.
