Generalized atherosclerosis

This code represents a widespread hardening and narrowing of the arteries throughout the body due to plaque buildup, without specifying a particular arterial site. It indicates a systemic atherosclerotic process affecting multiple vascular beds.

Use this code when documentation broadly states "generalized atherosclerosis" or "diffuse atherosclerosis" without further specificity of the affected arteries. This code is appropriate when the physician identifies atherosclerosis as a systemic condition impacting the patient's overall health, but does not pinpoint a specific anatomical location.

• Do not use this code if a more specific site of atherosclerosis (e.g., coronary, renal, peripheral) is documented; always code to the highest level of specificity.
• This code is often used as a secondary diagnosis to indicate underlying vascular disease contributing to other conditions.
• Ensure documentation supports the "generalized" nature; avoid using this code if only one or two specific sites are mentioned.
