About X00.4XXD

X00.4XXD is the ICD-10-CM diagnosis code for hit by object from burning building or structure in uncontrolled fire, subsequent encounter. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

The 7th character "D" means subsequent encounter: use it for encounters after active treatment, while the patient is healing or recovering.

Code first: any associated cataclysm.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

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

Before ICD-10, this condition was coded in ICD-9-CM as E890.8 (other accident resulting from conflagration in private dwelling).
