ICD-10 Code I87.319 – Chronic venous hypertension (idiopathic) with ulcer of unspecified lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.319 – Chronic venous hypertension (idiopathic) with ulcer of unspecified lower extremity
What it is
This code identifies chronic venous hypertension of unknown cause with an ulcer on an unspecified lower leg. Use it when the record shows venous disease and an ulcer, but the exact leg site is not documented.
Clinical signs
Typical findings include chronic venous stasis changes, edema, skin discoloration, and a lower-extremity ulcer. Clinical features vary; refer to documentation for laterality and whether the ulcer is active or healing.
When to use this code
Use I87.319 when the provider documents idiopathic chronic venous hypertension and an ulcer of the lower extremity, but does not specify right or left. It also fits when the ulcer is linked to venous hypertension and the documentation lacks a more precise site.
Choose this code only after confirming the venous etiology in the record. If the ulcer is documented at a specific leg site, or if another cause is stated, code that information instead.
Do not use for
Do not use this code for ulcers without documented venous hypertension or when the cause is arterial, diabetic, pressure-related, or traumatic. Check documentation if the ulcer site or etiology is unclear.
Coding tip
Always verify both the venous diagnosis and the unspecified lower-extremity location before assigning I87.319.
