About X77.0
X77.0 is the ICD-10-CM diagnosis code for intentional self-harm by steam or hot vapors. 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), X77.0 is specifically for intentional self-harm by steam or hot vapors. Related codes cover hot tap water (X77.1), 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.
