ICD-10 Code I87.333 – Chronic Venous Hypertension (Idiopathic) with Ulcer and Inflammation of Bilateral Lower Extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.333 – Chronic venous hypertension (idiopathic) with ulcer and inflammation of bilateral lower extremity
What it is
This code identifies chronic venous hypertension, or long-standing high pressure in the leg veins, caused by idiopathic disease and complicated by an ulcer with inflammation in both lower extremities. Use it when the record links venous disease to bilateral ulceration and inflammation.
Clinical signs
Typical findings include chronic leg swelling, skin discoloration, venous stasis changes, and an open ulcer on both lower legs with surrounding inflammation. Clinical features vary; refer to documentation.
When to use this code
Use I87.333 when the provider documents chronic venous hypertension of idiopathic cause with ulcer and inflammation affecting both lower extremities. The chart should support bilateral involvement and the presence of both ulceration and inflammatory changes. If the documentation is incomplete, check documentation before coding.
Do not use for
Do not use this code if the ulcer is not documented as venous, if inflammation is absent, or if only one lower extremity is involved. Do not assign it when the cause or laterality is unclear.
Coding tip
Verify that the record explicitly ties the ulcer and inflammation to chronic venous hypertension and states bilateral lower-extremity involvement.
