X02.4Hit by object from burning building or structure in controlled fire

X02.4 is the ICD-10-CM diagnosis code for hit by object from burning building or structure in controlled fire. It belongs to category X02 (exposure to controlled fire 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 X02 (exposure to controlled fire in building or structure), X02.4 is specifically for hit by object from burning building or structure in controlled fire. Related codes cover exposure to flames in controlled fire in building or structure (X02.0), exposure to smoke in controlled fire in building or structure (X02.1), injury due to collapse of burning building or structure in controlled fire (X02.2), fall from burning building or structure in controlled fire (X02.3), jump from burning building or structure in controlled fire (X02.5) and other exposure to controlled fire in building or structure (X02.8).

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.
