Q25.4
Q25.4 — Other congenital malformations of aorta
Non-billable headerICD-10-CM
Q25.4 is a non-billable header ICD-10-CM code for other congenital malformations of aorta. It cannot be billed on its own: choose one of the more specific child codes below.

- hypoplasia of aorta in hypoplastic left heart syndrome (Q23.4)

Q25.4 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.
Code to one of these instead Q25.4
