Venous insufficiency (chronic) (peripheral)

This code represents a condition where the veins, typically in the legs, have difficulty returning blood to the heart, leading to blood pooling. This chronic dysfunction of venous valves or obstruction results in sustained venous hypertension. It specifically refers to long-standing or peripheral venous insufficiency.

Use this code when documentation clearly indicates chronic venous insufficiency, often presenting with symptoms like edema, aching, or heaviness in the limbs, without specifying varicose veins with stasis dermatitis. This diagnosis is supported by findings such as incompetent venous valves on ultrasound or clinical signs of chronic venous stasis.

• Do not code with I83.1- or I83.2- as per the Excludes1 note, which specifies stasis dermatitis with varicose veins of lower extremities.
• Ensure documentation specifies "chronic" or "peripheral" venous insufficiency to differentiate from acute or unspecified forms.
• Consider additional codes for associated symptoms or complications, such as edema (R60.0) or pain (R10.83), if separately documented and treated.
