Q64 — Other congenital malformations of urinary system
Is Q64 billable?
No — Q64 is a non-billable header code. Q64 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 22 billable codes beneath Q64.
