About X77

X77 is the ICD-10-CM diagnosis code for intentional self-harm by steam, hot vapors and hot objects. It belongs to block X71-X83 (intentional self-harm) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: X77.0 (vapors), X77.1 (water), X77.2 (fluids), X77.3 (appliances), X77.8 (objects) and X77.9 (objects).

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