W85 — Exposure to electric transmission lines
W85 is a non-billable header ICD-10-CM code for exposure to electric transmission lines. 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.

Risk adjustment
W85 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 W85 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 W85.
- Broken›power line(causing electric shock)
- Exposure›transmission line, electric(s)
- Exposure›electric current›high-voltage cable
- Exposure›electric current›transmission lines
Code to one of these instead W85
3 child codes. Green means billable.
