About W86.1

W86.1 is the ICD-10-CM diagnosis code for exposure to industrial wiring, appliances and electrical machinery. It belongs to category W86 (exposure to other specified electric current), 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 W86 (exposure to other specified electric current), W86.1 is specifically for exposure to industrial wiring, appliances and electrical machinery. Related codes cover domestic wiring and appliances (W86.0) and other electric current (W86.8).

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.
