ICD-10 Code I87.31 – Chronic venous hypertension (idiopathic) with ulcer (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.31 – Chronic venous hypertension (idiopathic) with ulcer
What it is
I87.31 identifies chronic venous hypertension of the legs, caused by venous valve failure or obstruction, with an associated ulcer. It describes a long-standing venous circulation problem that has led to skin breakdown.
Clinical signs
Typical findings include lower-extremity edema, skin discoloration, varicosities, and a venous ulcer, usually near the ankle. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents chronic venous hypertension and a venous ulcer, and the provider identifies the condition as idiopathic. It fits chronic venous disease with ulceration, not an acute clotting event. Confirm laterality and ulcer details if documented.
Do not use for
Do not use this code for ulcers without documented chronic venous hypertension, or for ulcers clearly caused by arterial, diabetic, pressure, or traumatic etiologies. Check documentation.
Coding tip
Capture the ulcer site and laterality from the note, and code the venous hypertension diagnosis only when the provider explicitly links it to the ulcer.
