About W86.1XXA
W86.1XXA is the ICD-10-CM diagnosis code for exposure to industrial wiring, appliances and electrical machinery, initial encounter. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
The 7th character "A" means initial encounter: use it while the patient is receiving active treatment for the condition.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as E925.2 (accident caused by industrial wiring, appliances, and electrical machinery).
