Q84

Q84 — Other congenital malformations of integument

Non-billable headerICD-10-CM

Q84 is a non-billable header ICD-10-CM code for other congenital malformations of integument. It cannot be billed on its own: choose one of the more specific child codes below.

Other codes that can never be billed with Q84

These codes carry an Excludes1 note pointing at Q84. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q84 alone.

L67Hair color and hair shaft abnormalities
L68Hypertrichosis
P83Other conditions of integument specific to newborn

Risk adjustment

Q84 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 Q84

9 child codes. Green means billable.
