Q22

Q22 — Congenital malformations of pulmonary and tricuspid valves

Non-billable headerICD-10-CM

Q22 is a non-billable header ICD-10-CM code for congenital malformations of pulmonary and tricuspid valves. It cannot be billed on its own: choose one of the more specific child codes below.

Other codes that can never be billed with Q22

These codes carry an Excludes1 note pointing at Q22. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q22 alone.

I36Nonrheumatic tricuspid valve disorders
I37Nonrheumatic pulmonary valve disorders

Risk adjustment

Q22 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 Q22

9 child codes. Green means billable.
