Q39

Q39 — Congenital malformations of esophagus

Non-billable headerICD-10-CM

Q39 is a non-billable header ICD-10-CM code for congenital malformations of esophagus. It cannot be billed on its own: choose one of the more specific child codes below.

Other codes that can never be billed with Q39

These codes carry an Excludes1 note pointing at Q39. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q39 alone.

K22.0Achalasia of cardia
K22.2Esophageal obstruction
K22.5Diverticulum of esophagus, acquired

Risk adjustment

Q39 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 Q39

9 child codes. Green means billable.
