W90.2Exposure to laser radiation

W90.2 is the ICD-10-CM diagnosis code for exposure to laser radiation. It belongs to category W90 (exposure to other nonionizing radiation), 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 W90 (exposure to other nonionizing radiation), W90.2 is specifically for exposure to laser radiation. Related codes cover radiofrequency (W90.0), infrared radiation (W90.1) and other nonionizing radiation (W90.8).

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.
