X98.0Assault by steam or hot vapors

X98.0 is the ICD-10-CM diagnosis code for assault by steam or hot vapors. It belongs to category X98 (assault by steam, hot vapors and hot objects), 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.

Within X98 (assault by steam, hot vapors and hot objects), X98.0 is specifically for assault by steam or hot vapors. Related codes cover hot tap water (X98.1), hot fluids (X98.2), hot household appliances (X98.3), other hot objects (X98.8) and unspecified hot objects (X98.9).

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.
