ICD-10 Code I87.313 – Chronic venous hypertension (idiopathic) with ulcer of bilateral lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.313 – Chronic venous hypertension (idiopathic) with ulcer of bilateral lower extremity
What it is
This code identifies chronic venous hypertension from an idiopathic cause, complicated by an ulcer on both lower extremities. Use it when documentation links the ulcer to long-standing venous pressure problems and does not identify another cause.
Clinical signs
Typical findings include chronic leg swelling, skin discoloration, varicosities, and an open ulcer near the lower leg or ankle. Clinical features vary; refer to documentation for laterality, ulcer location, and any described venous insufficiency.
When to use this code
Use I87.313 when the provider documents chronic venous hypertension, idiopathic, with ulceration affecting both lower extremities. The record should clearly connect the ulcer to venous disease rather than trauma, diabetes, pressure, or arterial disease. If the ulcer site or laterality is unclear, check documentation before coding.
Do not use for
Do not use this code for venous hypertension without ulcer, or when the ulcer is due to another documented cause. If the condition is secondary to another disease, or the ulcer is not bilateral, choose the more accurate documented code.
Coding tip
Verify that “idiopathic” and bilateral ulcer involvement are both documented before assigning I87.313.
