ICD-10 Code I83.009 – Varicose veins of unspecified lower extremity with ulcer of unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.009 – Varicose veins of unspecified lower extremity with ulcer of unspecified site
What it is
This code identifies varicose veins in a lower extremity when the affected leg is not specified and an ulcer is present, but the ulcer site is not documented. Use it when the record confirms both the venous disease and an associated ulcer.
Clinical signs
Typical findings include visible, enlarged superficial veins in a leg with skin breakdown or an open sore consistent with venous disease. Clinical features vary; refer to documentation for laterality and ulcer location.
When to use this code
Use I83.009 when the provider documents varicose veins of a lower limb and an ulcer, but does not specify right, left, or ulcer site. It is appropriate for outpatient, inpatient, or problem-list documentation when the diagnosis is established and no more specific code is available.
If laterality or ulcer location is documented elsewhere in the chart, code to the more specific option instead. Check documentation when the note is incomplete or the ulcer is described only as a wound without venous association.
Do not use for
Do not use this code for varicose veins without an ulcer, or for ulcers from arterial, diabetic, pressure, or traumatic causes. Do not assign it when the leg or ulcer site is specifically documented and a more detailed code applies.
Coding tip
Look for both venous varicosities and an ulcer diagnosis in the same record, and capture laterality and ulcer site whenever the documentation supports it.
