Coronary Artery Bypass Surgery

Coronary artery bypass surgery creates a new path for blood to flow to your heart. This surgery is sometimes called a coronary artery bypass graft (CABG) or heart bypass. It's the most common heart surgery in adults. You may need this surgery if you have a blocked or partially blocked artery in your heart.

Questions About Z95.1Overview

Is Z95.1 (Presence of cardiac and vascular implants and grafts) a billable code?

Can Z95.1 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because presence of aortocoronary bypass graft describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z95.1 exempt from POA reporting?
