I87: Other disorders of veins

I87.2: Venous insufficiency (chronic)(peripheral)

Venous insufficiency, specifically chronic peripheral venous insufficiency, is a condition affecting the veins, the blood vessels responsible for returning blood from various parts of your body back to your heart. When you have venous insufficiency, your veins struggle to send blood from your limbs back to your heart, typically due to damaged or weak valve structures within the veins. This can result in pooling or backward flow of blood, mostly noticeable in the legs due to the effect of gravity. Common symptoms include swelling of your legs or ankles, feeling of heaviness, aching, or cramping in your legs, as well as varicose veins. Skin changes such as discoloration and even ulcers in serious cases can also occur. This condition is generally ongoing and progressive, but its speed and severity can vary among individuals.
