ICD-10 Code I87.391 – Chronic venous hypertension (idiopathic) with other complications of right lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.391 – Chronic venous hypertension (idiopathic) with other complications of right lower extremity
What it is
This code identifies chronic venous hypertension in the right lower leg when the cause is idiopathic and the record notes other specified complications. It reflects long-standing impaired venous return with a documented complication beyond simple swelling.
Clinical signs
Findings may include leg edema, skin discoloration, varicosities, pain, heaviness, or venous stasis changes. Clinical features vary; refer to documentation.
When to use this code
Use I87.391 when the provider documents chronic venous hypertension affecting the right lower extremity and specifies an additional complication, but not a more specific listed complication. The idiopathic cause must be stated or implied by the chosen code. Check documentation if the record only says venous insufficiency, edema, or varicose veins without chronic venous hypertension.
Do not use for
Do not use this code for left-sided or bilateral disease, or when the complication is better described by a more specific ICD-10-CM code. Do not assign it if chronic venous hypertension is not documented.
Coding tip
Verify laterality and the exact complication in the note before coding, because those details determine whether I87.391 is appropriate.
