ICD-10 Code I87.322 – Chronic venous hypertension (idiopathic) with inflammation of left lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.322 – Chronic venous hypertension (idiopathic) with inflammation of left lower extremity
What it is
I87.322 identifies chronic venous hypertension in the left lower extremity when the cause is idiopathic and inflammation is present. It describes long-term venous pressure problems affecting one leg, with inflammatory changes documented.
Clinical signs
You may see leg swelling, skin discoloration, aching, heaviness, or inflammatory skin changes in the left lower limb. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic venous hypertension in the left leg, specifies idiopathic origin, and notes inflammation. It is appropriate for chronic venous disease with inflammatory findings, not just simple venous insufficiency. Check documentation if laterality or etiology is unclear.
Do not use for
Do not use it if the record does not specify idiopathic cause or left-sided involvement. Avoid this code for venous hypertension without inflammation or for other venous disorders with a different documented diagnosis.
Coding tip
Match all three elements exactly: chronic venous hypertension, idiopathic etiology, and left lower extremity inflammation.
