Exposure to man-made visible and ultraviolet light (W89)
The W89 ICD-10 codes cover exposure to man-made visible and ultraviolet light sources, such as welding arcs, tanning beds, and other artificial UV lights. These codes help document injuries or skin conditions caused by overexposure to specific light types in medical records accurately.
Codes like W89.0 specify exposure to welding light (arc), including initial encounters (W89.0XXA), subsequent visits, and sequelae. Common terms linked to these codes are "overexposure to arc lamp radiation" or "exposure to welding arc," assisting coders in identifying work-related eye or skin injuries from electrical welding. The W89.1 series focuses on tanning bed exposure, marked by terms such as "addiction to sunbed use," emphasizing its potential for skin damage from artificial tanning devices. The W89.8 codes cover other man-made light exposures like ultraviolet phototherapy, including burns and skin reactions from black lights or PUVA treatment, often referencing "adverse effects from PUVA photochemotherapy." Lastly, W89.9 is for unspecified man-made visible or ultraviolet light exposure, capturing various conditions like phototoxic reactions, Stevens-Johnson syndrome from light exposure, and artificial ultraviolet induced skin pigmentation. Using these codes supports precise classification of conditions caused by different artificial light exposures in clinical documentation.

Instructional Notations
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- exposure to welding light (arc)
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.
- exposure to sunlight X32
7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
- The appropriate 7th character is to be added to each code from category W89
7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
- A - initial encounter
- D - subsequent encounter
- S - sequela
