O28.8
O28.8 — Other abnormal findings on antenatal screening of mother
Billable / specific codeICD-10-CM
O28.8 is a billable, specific ICD-10-CM code for other abnormal findings on antenatal screening of mother. It is valid for submission on a claim.
Risk adjustment
O28.8 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.
