Exposure to smoke, fire and flames (X00-X08) ICD-10-CM
The X00–X08 section covers exposure to smoke, fire and flames with 169 ICD-10-CM diagnosis codes, of which 120 are billable in fiscal year 2026. The section is organized into the 8 code ranges listed below.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the X00–X08 Code Range
ICD-10 codes X00 through X08 classify various situations involving exposure to smoke, fire, and flames, whether from uncontrolled or controlled fires in buildings, structures, or open areas. They cover different causes such as flames, smoke inhalation, falls, or injuries related to burning buildings, furniture, or clothing. These codes also track the stage of care including initial treatment, follow-up visits, and late effects (sequela).
This ICD-10 range details incidents like exposure to flames in a house fire (X00.0), smoke inhalation from uncontrolled building fires (X00.1), injuries from collapsing burning structures (X00.2), and falls or jumps from burning buildings (X00.3 and X00.5). Synonyms such as "house fire," "conflagration in private dwelling," and "carbon monoxide fumes from conflagration" help clarify appropriate code use. The classification extends to fires outside buildings, such as forest fires or wildfires (X01), and controlled fires like charcoal or gas fires inside residences (X02). Specialized codes address ignition or melting of highly flammable materials (X04) and clothing or nightwear catching fire (X05, X06). Exposure to specific furniture fires, including bed or sofa fires, is also included (X08), with synonyms like "burning bedclothes" aiding accuracy. These detailed codes support precise documentation of fire-related injuries and exposures for both clinical care and reporting purposes.
