X03.0Exposure to flames in controlled fire, not in building or structure

X03.0 is the ICD-10-CM diagnosis code for exposure to flames in controlled fire, not in building or structure. It belongs to category X03 (exposure to controlled fire, not in building or structure), block X00-X08 (exposure to smoke, fire and flames) 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 X03 (exposure to controlled fire, not in building or structure), X03.0 is specifically for exposure to flames in controlled fire, not in building or structure. Related codes cover exposure to smoke in controlled fire, not in building or structure (X03.1), fall due to controlled fire, not in building or structure (X03.3), hit by object due to controlled fire, not in building or structure (X03.4) and other exposure to controlled fire, not in building or structure (X03.8).

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.
