Other codes that can never be billed with S02.40C
These codes carry an Excludes1 note pointing at S02.40C. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S02.40C alone.
- S01Open wound of head
Risk adjustment
S02.40C 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.

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 S02.40C.
