O11.4
O11.4 — Pre-existing hypertension with pre-eclampsia, complicating childbirth
Billable / specific codeICD-10-CM
O11.4 is a billable, specific ICD-10-CM code for pre-existing hypertension with pre-eclampsia, complicating childbirth. It is valid for submission on a claim.
Risk adjustment
O11.4 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.
