ICD-10 Code I87.392 – Chronic venous hypertension (idiopathic) with other complications of left lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.392 – Chronic venous hypertension (idiopathic) with other complications of left lower extremity
What it is
This code identifies chronic venous hypertension in the left lower leg when the cause is idiopathic, meaning no specific underlying cause is documented, and the chart notes other complications beyond simple swelling.
Clinical signs
Typical findings include chronic leg edema, skin discoloration, aching, heaviness, or venous stasis changes in the left lower extremity. Clinical features vary; refer to documentation.
When to use this code
Use I87.392 when the provider documents chronic venous hypertension of the left leg, labels it idiopathic, and notes a complication that is not captured by a more specific venous code. Confirm the laterality and the documented complication in the record. If the cause is described differently, or the condition is bilateral, check documentation.
Do not use for
Do not use this code for uncomplicated venous insufficiency, varicose veins, or edema without documented chronic venous hypertension. Also avoid it when the provider does not specify the left lower extremity or the idiopathic nature of the condition.
Coding tip
Verify both laterality and the exact complication wording before assigning I87.392.
