Exposure to excessive heat of man-made origin (W92)

The ICD-10 code W92 covers cases of exposure to excessive heat originating from man-made sources. This includes situations such as heat exposure from heaters, factory equipment, and open fires in controlled environments.

The code W92 and its variations with seventh characters; for initial encounter (W92.XXXA), subsequent encounter (W92.XXXD), and sequela (W92.XXXS); are used specifically for recording injuries or conditions caused by exposure to man-made heat sources. These might include accidents due to heat in locations like boiler rooms, drying rooms, kitchens, or transport vehicles, as well as exposure to radiant heat from gas, electric, or paraffin heaters, and open solid fuel fires. Synonyms such as "accidents due to excessive heat" or "exposure to radiant heat from open fire" help clarify situations involving man-made heat. Knowing the correct ICD-10 code for exposure to excessive heat of man-made origin assists medical coders in accurately documenting these environmental injury causes for treatment and statistical purposes.
