Other disorders of veins (I87)

ICD-10 code section I87 covers other disorders of veins, primarily used to classify conditions affecting venous structures beyond common varicose veins. This set includes detailed codes for complications like postthrombotic syndrome, vein compressions, chronic venous insufficiency, and various venous hypertension disorders.

This code group distinctly addresses postthrombotic syndrome (I87.0), which is also known by synonyms such as post-thrombotic syndrome of right or left lower extremity or venous insufficiency of leg. Specific subcodes differentiate cases with or without ulcers or inflammation, and specify affected limbs. The section also includes codes for chronic venous hypertension (I87.3), sometimes called idiopathic chronic venous hypertension, with options indicating whether ulcers or inflammation are present, helping coders pinpoint exact clinical details. Additionally, compression of veins (I87.1) covers conditions like superior vena cava syndrome and venous obstruction syndromes. Miscellaneous venous disorders are captured under other specified (I87.8) or unspecified vein disorders (I87.9), including rare vascular abnormalities or postprocedural complications. Using these codes allows precise documentation and tracking of complex venous diseases for medical billing and clinical care.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

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.

Superior Vena Cava Syndrome

A condition that occurs when the obstruction of the thin-walled SUPERIOR VENA CAVA interrupts blood flow from the head, upper extremities, and thorax to the RIGHT ATRIUM. Obstruction can be caused by NEOPLASMS; THROMBOSIS; ANEURYSM; or external compression. The syndrome is characterized by swelling and/or CYANOSIS of the face, neck, and upper arms which is called Pemberton's sign. Classification of SVC obstruction is often based on COLLATERAL CIRCULATION.

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.
