2026 ICD-10-CM Diagnosis Code I87.303 – Chronic venous hypertension (idiopathic) without complications of bilateral lower extremity
What it is
This code identifies chronic venous hypertension in both lower extremities when the cause is idiopathic and no complications are documented. Use it for long-standing venous pressure problems affecting both legs.
Clinical signs
Findings may include leg heaviness, swelling, aching, and visible varicose veins. Clinical features vary; refer to documentation, and confirm that no ulcers, inflammation, or other complications are recorded.
When to use this code
Use I87.303 when the provider documents chronic venous hypertension affecting both lower legs and specifically states idiopathic origin without complications. It is appropriate for outpatient, inpatient, or problem-list documentation when bilateral disease is clear. Check documentation if laterality or complications are unclear.
Do not use for
Do not use this code if the record describes venous hypertension with ulceration, inflammation, or other complications. Also avoid it when the condition is unilateral or when the documentation does not support an idiopathic cause.
Coding tip
Verify bilateral lower-extremity involvement and absence of complications before assigning I87.303.
