ICD-10 Code I87.393 – Chronic venous hypertension (idiopathic) with other complications of bilateral lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.393 – Chronic venous hypertension (idiopathic) with other complications of bilateral lower extremity
What it is
I87.393 identifies chronic venous hypertension caused by idiopathic venous disease in both lower extremities, with additional complications. Use it when documentation shows persistent venous pressure problems in both legs and a specified complication.
Clinical signs
Common findings include chronic leg swelling, heaviness, skin discoloration, varicosities, or venous stasis changes. Clinical features vary; refer to documentation for the exact complication, such as ulceration, inflammation, or other venous sequelae.
When to use this code
Use this code when the provider documents chronic venous hypertension, idiopathic origin, and bilateral lower-extremity involvement with another specified complication. It fits cases where the record clearly distinguishes this from uncomplicated venous disease or from unilateral disease. Check documentation if the complication is not named.
Do not use for
Do not use this code for uncomplicated chronic venous hypertension or when the condition is limited to one leg. Do not assign it if the documentation does not support idiopathic etiology or does not specify the associated complication.
Coding tip
Verify both laterality and the documented complication before assigning I87.393.
