ICD-10 Code I87.339 – Chronic venous hypertension (idiopathic) with ulcer and inflammation of unspecified lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.339 – Chronic venous hypertension (idiopathic) with ulcer and inflammation of unspecified lower extremity
What it is
This code identifies chronic venous hypertension without a known cause, complicated by both ulceration and inflammation in an unspecified lower leg. Use it when the record supports venous disease affecting the lower extremity but does not name a specific side.
Clinical signs
Typical findings include chronic leg swelling, skin discoloration, venous stasis changes, and an open ulcer with surrounding inflammation. Clinical features vary; refer to documentation for laterality and whether the ulcer is active.
When to use this code
Use I87.339 when the provider documents chronic venous hypertension as idiopathic and notes both ulcer and inflammation, but does not specify right or left lower extremity. It is appropriate for outpatient, inpatient, and wound-care records when the diagnosis is clearly stated. Check documentation if the ulcer location or laterality is unclear.
Do not use for
Do not use this code for venous hypertension with no ulcer or no inflammation, or when the cause is documented as another condition. If the affected side is known, choose the more specific laterality code instead.
Coding tip
Confirm that the note links the ulcer and inflammation to chronic venous hypertension before assigning this code.
