X00.4Hit by object from burning building or structure in uncontrolled fire

X00.4 is the ICD-10-CM diagnosis code for hit by object from burning building or structure in uncontrolled fire. It belongs to category X00 (exposure to uncontrolled 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 X00 (exposure to uncontrolled fire in building or structure), X00.4 is specifically for hit by object from burning building or structure in uncontrolled fire. Related codes cover exposure to flames in uncontrolled fire in building or structure (X00.0), exposure to smoke in uncontrolled fire in building or structure (X00.1), injury due to collapse of burning building or structure in uncontrolled fire (X00.2), fall from burning building or structure in uncontrolled fire (X00.3), jump from burning building or structure in uncontrolled fire (X00.5) and other exposure to uncontrolled fire in building or structure (X00.8).

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.

Code first: any associated cataclysm.

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