Exposure to electric current, radiation and extreme ambient air temperature and pressure (W85-W99)
This ICD-10 range W85-W99 captures medical codes for injuries and health conditions caused by exposure to electric currents, various forms of radiation, and extreme man-made environmental factors such as heat, cold, and air pressure changes. These codes help classify both initial injuries and their follow-up care or complications.
The codes from W85 to W86 cover electric current exposure including contact with electric transmission lines, domestic wiring, and industrial electrical machinery. Terms like "accident caused by central electric current" or "exposure to electric current from electric transmission lines" direct coders and clinicians to these specific injury types. Radiation exposures are detailed in categories W88 through W90, including ionizing radiation (like X-rays, radioactive isotopes, and other ionizing sources) and nonionizing radiation exposures such as radiofrequency, infrared, laser, and microwave radiation. Codes under W89 relate to man-made visible and ultraviolet light exposures, including welding light or tanning beds, with synonyms such as "overexposure to visual and ultraviolet light sources" or "addiction to sunbed use." Cold and heat injuries from man-made sources are covered under W92 and W93, specifying types like boiler room heat injuries or contact with dry ice and liquid air. Finally, codes from W94 to W99 address injuries from rapid or prolonged changes in air pressure, including diving accidents, aircraft cabin pressure loss, and other man-made environmental factors. This coding structure helps precisely document exposures, initial encounters, subsequent care, and sequelae for accurate clinical and billing documentation.

Instructional Notations
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.
