ICD-10 Code I87.311 – Chronic venous hypertension (idiopathic) with ulcer of right lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.311 – Chronic venous hypertension (idiopathic) with ulcer of right lower extremity
What it is
I87.311 identifies chronic venous hypertension of the right leg when poor venous return is associated with a lower-extremity ulcer. It indicates a chronic venous disorder, not an arterial or diabetic ulcer.
Clinical signs
Typical findings include leg edema, skin discoloration, varicosities, and a venous stasis ulcer on the right lower extremity. Clinical features vary; refer to documentation for ulcer location and venous cause.
When to use this code
Use this code when the record clearly states chronic venous hypertension, idiopathic, with an ulcer on the right lower leg or foot. You should also see documentation linking the ulcer to venous disease and specifying the right side.
If the note only says venous insufficiency, edema, or ulcer without laterality or venous etiology, check documentation before assigning I87.311. Confirm that the ulcer is not described as arterial, diabetic, or pressure-related.
Do not use for
Do not use this code for ulcers from diabetes, arterial disease, pressure injury, or trauma. If the venous hypertension is not documented as idiopathic or the right lower extremity is not specified, check documentation.
Coding tip
Verify both the venous diagnosis and the right-sided ulcer location in the same record before coding I87.311.
