- Maternal care for disproportion due to cephalopelvic disproportion NOS
- Maternal care for disproportion due to fetopelvic disproportion NOS
Risk adjustment
O33.9 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.
