Q07.0 — Arnold-Chiari syndrome
Is Q07.0 billable?
No — Q07.0 is a non-billable header code. Q07.0 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 4 billable codes beneath Q07.0.
