Necrosis of artery

This code represents the death of arterial tissue, often due to a lack of blood supply (ischemia) or other pathological processes. It signifies irreversible cellular injury leading to the breakdown of arterial wall components. This condition can affect any artery in the body.

Use this code when documentation explicitly states necrosis of an artery, such as in cases of arterial gangrene, severe vasculitis leading to tissue death, or complications of arterial injury. Supporting documentation should clearly identify the artery involved and confirm the necrotic state of the arterial tissue.

• Do not use this code for simple arterial occlusion or stenosis without documented tissue death of the artery itself.
• Always code the underlying cause of the arterial necrosis, if known, as a primary diagnosis when applicable.
• Be sure to specify the affected artery with a more specific code if available and documented (e.g., necrosis of specific peripheral arteries).
