Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the I87 range.
Postthrombotic Syndrome
A condition caused by one or more episodes of DEEP VEIN THROMBOSIS, usually the blood clots are lodged in the legs. Clinical features include EDEMA; PAIN; aching; heaviness; and MUSCLE CRAMP in the leg. When severe leg swelling leads to skin breakdown, it is called venous STASIS ULCER.
Venous Insufficiency
Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
About the I87 Code Range
These disorders affect veins and include problems after a clot, vein compression, long-term venous insufficiency, and high pressure in veins.
I87.0 covers postthrombotic syndrome, meaning problems after a clot. I87.1 identifies vein compression, while I87.2 identifies long-term peripheral venous insufficiency, or veins that do not work well.
I87.3 covers long-term high vein pressure without a known cause. Both it and postthrombotic syndrome split by whether an ulcer, inflammation, both, other complications, or no complications are present. Their subdivisions then distinguish the right, left, both, or an unspecified lower extremity. I87.8 covers other specified vein disorders; I87.9 covers an unspecified vein disorder.
