Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.

Risk adjustment
O23 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.
