About X17

X17 is the ICD-10-CM diagnosis code for contact with hot engines, machinery and tools. It belongs to block X10-X19 (contact with heat and hot substances) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: X17.XXXA (initial encounter), X17.XXXD (subsequent encounter) and X17.XXXS (sequela).

Don't report X17 together with the conditions in its Excludes1 note: contact with hot heating appliances, radiators and pipes (X16) and contact with hot household appliances (X15).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
