Q40 — Other congenital malformations of upper alimentary tract

Not billable

Is Q40 billable?

No — Q40 is a non-billable header code. Q40 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 6 billable codes beneath Q40.
