Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Broken power line

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.

  • Brokenpower line(causing electric shock)
  • Exposuretransmission line, electric(s)
  • Exposureelectric currenthigh-voltage cable
  • Exposureelectric currenttransmission lines

Code to one of these instead W85

3 child codes. Green means billable.
