Inclusion terms

- Impacted shoulders
Other codes that can never be billed with O66.0
These codes carry an Excludes1 note pointing at O66.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O66.0 alone.

- O64.4XX0Obstructed labor due to shoulder presentation, not applicable or unspecified
- O64.4XX1Obstructed labor due to shoulder presentation, fetus 1

Risk adjustment
O66.0 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 O66.0 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 O66.0.
