Q25
Q25 — Congenital malformations of great arteries
Non-billable headerICD-10-CM
Q25 is a non-billable header ICD-10-CM code for congenital malformations of great arteries. It cannot be billed on its own: choose one of the more specific child codes below.
Other codes that can never be billed with Q25
These codes carry an Excludes1 note pointing at Q25. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q25 alone.
Risk adjustment
Q25 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.
