Q25.45

Billable

Double aortic arch

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A congenital condition where the aorta (main artery from the heart) splits into two arches instead of one, which can restrict blood flow to the lungs and esophagus.

Coding Tips

  • •This is a structural heart defect present at birth; verify imaging confirmation (echocardiogram or CT) in the medical record
  • •May be associated with symptoms like difficulty swallowing or breathing; document any associated conditions separately
