About W85

W85 is the ICD-10-CM diagnosis code for exposure to electric transmission lines. It belongs to 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.

To report this condition, pick the subcode that matches the documentation: W85.XXXA (initial encounter), W85.XXXD (subsequent encounter) and W85.XXXS (sequela).

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