Presence of aortocoronary bypass graft

This code indicates that a patient has undergone a surgical procedure to bypass blocked coronary arteries using a graft from the aorta. It signifies the current existence of this bypass, which improves blood flow to the heart muscle. This intervention is typically performed to treat coronary artery disease.

Use this code for patients who have a documented history of coronary artery bypass graft (CABG) surgery and the graft is still present. This applies to both initial encounters and subsequent visits where the presence of the graft is relevant to the patient's ongoing care or condition. Do not use this code for patients who have had the graft removed or who are being evaluated for potential CABG.

• Always confirm the documentation explicitly states the presence of the graft, not just a history of CABG.
• This code is often used as a secondary diagnosis to provide context for other cardiovascular conditions or complications.
• Distinguish from Z95.5 (Presence of coronary angioplasty implant and graft) which specifies an angioplasty implant and a graft.
