X77.1Intentional self-harm by hot tap water

X77.1 is the ICD-10-CM diagnosis code for intentional self-harm by hot tap water. It belongs to category X77 (intentional self-harm by steam, hot vapors and hot objects), 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 3 subcodes must be used instead.

Within X77 (intentional self-harm by steam, hot vapors and hot objects), X77.1 is specifically for intentional self-harm by hot tap water. Related codes cover steam or hot vapors (X77.0), other hot fluids (X77.2), hot household appliances (X77.3), other hot objects (X77.8) and unspecified hot objects (X77.9).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

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