About X97
X97 is the ICD-10-CM diagnosis code for assault by smoke, fire and flames. It belongs to block X92-Y09 (assault) 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: X97.XXXA (initial encounter), X97.XXXD (subsequent encounter) and X97.XXXS (sequela).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
