W86.1 — Exposure to industrial wiring, appliances and electrical machinery
W86.1 is a non-billable header ICD-10-CM code for exposure to industrial wiring, appliances and electrical machinery. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.
This code requires a 7th character
The appropriate 7th character is to be added to each code from category W86
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Exposure to conductors
- Exposure to control apparatus
- Exposure to electrical equipment and machinery
- Exposure to transformers
Other codes that can never be billed with W86.1
These codes carry an Excludes1 note pointing at W86.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W86.1 alone.
- X16Contact with hot heating appliances, radiators and pipes
- X16.XXXAContact with hot heating appliances, radiators and pipes, initial encounter
- X16.XXXDContact with hot heating appliances, radiators and pipes, subsequent encounter
- X16.XXXSContact with hot heating appliances, radiators and pipes, sequela
Risk adjustment
W86.1 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
How W86.1 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to W86.1.
- Exposure›electric current›conductor(faulty)
- Exposure›electric current›control apparatus(faulty)
- Exposure›electric current›electric power generating plant, distribution station
- Exposure›electric current›transformer(faulty)
Code to one of these instead W86.1
