About X12

X12 is the ICD-10-CM diagnosis code for contact with other hot fluids. 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: X12.XXXA (initial encounter), X12.XXXD (subsequent encounter) and X12.XXXS (sequela).

Don't report X12 together with the conditions in its Excludes1 note: hot (liquid) metals (X18).

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