Q25.21

Billable

Interruption of aortic arch

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

What This Code Means

A rare congenital heart defect where the aortic arch is completely broken or interrupted, preventing normal blood flow to the lower body.

Coding Tips

  • •This is a critical condition often requiring early surgical intervention; document associated anomalies like DiGeorge syndrome
  • •Specify which segment of the aortic arch is interrupted (between left common carotid and left subclavian artery is most common)
