Breakdown (mechanical) of coronary artery bypass graft, init

This code signifies a mechanical failure of a coronary artery bypass graft (CABG), such as a fracture, kinking, or disconnection of the graft itself, or a problem with the anastomotic site. This breakdown is not due to an underlying disease process like atherosclerosis, but rather a structural or functional issue with the implanted graft.

Use this code when a patient presents with symptoms directly attributable to a physical malfunction of their CABG, requiring intervention or evaluation. This includes cases where imaging reveals a structural defect in the graft or its connection points, leading to compromised blood flow. This code is appropriate for the initial episode of care for this specific mechanical complication.

• Ensure documentation clearly specifies a mechanical breakdown of the graft, not a re-stenosis or occlusion due to disease.
• Confirm this is the initial encounter for this specific complication; subsequent encounters would use a different seventh character.
• Look for terms like "fracture," "kink," "disconnection," or "structural failure" of the bypass graft.
