External causes of morbidity (V00-Y99), in the block Exposure to animate mechanical forces (W50-W64).

What cannot be coded together with W50.0?

Non-billable headerICD-10-CM

Excludes1 inherited from the categories above W50.0

These are not written on W50.0, but they bind it: a note on a category applies to every code beneath it. Billing W50.0 with anything listed here is a denial.

Written on W50 — Accidental hit, strike, kick, twist, bite or scratch by another person

assault by bodily force (Y04)
struck by objects (W20-W22)

Risk adjustment

W50.0 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 W50.0 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 W50.0.
