Q51Congenital malformations of uterus and cervix

Non-billable headerICD-10-CM

Q51 is a non-billable header ICD-10-CM code for congenital malformations of uterus and cervix. It cannot be billed on its own: choose one of the more specific child codes below.

Other codes that can never be billed with Q51

These codes carry an Excludes1 note pointing at Q51. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q51 alone.

Risk adjustment

Q51 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 Q51

10 child codes. Green means billable.
