W89.0Exposure to welding light (arc)

W89.0 is the ICD-10-CM diagnosis code for exposure to welding light (arc). It belongs to category W89 (exposure to man-made visible and ultraviolet light), block W85-W99 (exposure to electric current, radiation and extreme ambient air temperature and pressure) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within W89 (exposure to man-made visible and ultraviolet light), W89.0 is specifically for exposure to welding light (arc). Related codes cover tanning bed (W89.1), other man-made visible and ultraviolet light (W89.8) and unspecified man-made visible and ultraviolet light (W89.9).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

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