ICD-10 Code I87.331 – Chronic venous hypertension (idiopathic) with ulcer and inflammation of right lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.331 – Chronic venous hypertension (idiopathic) with ulcer and inflammation of right lower extremity
What it is
This code identifies chronic venous hypertension in the right lower leg when a venous ulcer is present and the area shows inflammation. It reflects long-standing impaired venous return, not an arterial ulcer or acute infection.
Clinical signs
Typical findings include a chronic ulcer on the right lower extremity with surrounding redness, swelling, or skin irritation. Clinical features vary; refer to documentation for venous stasis changes, edema, and ulcer location.
When to use this code
Use I87.331 when the record clearly documents chronic venous hypertension, an ulcer on the right leg, and inflammation at that site. You should also confirm the condition is idiopathic and not due to another specified cause. If the note only says venous insufficiency or leg ulcer, check documentation before coding.
Do not use for
Do not use this code for arterial ulcers, pressure ulcers, diabetic foot ulcers, or ulcers without documented venous hypertension. Do not assign it if the inflammation is not documented or the right-sided location is unclear.
Coding tip
Verify the laterality, ulcer presence, and inflammation in the provider note before assigning I87.331.
