Q89

Q89 — Other congenital malformations, not elsewhere classified

Non-billable headerICD-10-CM

Q89 is a non-billable header ICD-10-CM code for other congenital malformations, not elsewhere classified. It cannot be billed on its own: choose one of the more specific child codes below.

Other codes that can never be billed with Q89

These codes carry an Excludes1 note pointing at Q89. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q89 alone.

Q18Other congenital malformations of face and neck
Q20Congenital malformations of cardiac chambers and connections
Q24.0Dextrocardia
D73.0Hyposplenism
D73.1Hypersplenism

Risk adjustment

Q89 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 Q89

8 child codes. Green means billable.
