Atherosclerosis of other specified arteries

This code signifies the hardening and narrowing of arteries due to plaque buildup (atherosclerosis) in locations other than the aorta, renal, mesenteric, or extremities. It indicates a systemic atherosclerotic process affecting various arterial beds not specifically classified elsewhere.

Use this code when documentation specifies atherosclerosis in arteries such as the carotid (without cerebral infarction), subclavian, or iliac arteries, provided there is no associated gangrene, rest pain, or ulceration. It is appropriate when the physician explicitly identifies atherosclerosis in a "specified" but "other" arterial site.

• Do not use this code for atherosclerosis of the coronary arteries; specific codes exist for those conditions.
• Ensure the documentation clearly identifies the specific "other" artery involved to support this code over a more general or unspecified code.
• Always sequence this code after any acute manifestations or complications directly resulting from the atherosclerosis, if applicable.
