ICD-10 Code I83.005 – Varicose veins of unspecified lower extremity with ulcer other part of foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.005 – Varicose veins of unspecified lower extremity with ulcer other part of foot
What it is
This code identifies varicose veins in an unspecified lower extremity when an ulcer is present on another part of the foot. Use it when the record links the venous disease to a foot ulcer, but laterality is not documented.
Clinical signs
Typical findings include visible, enlarged superficial veins and a venous ulcer on the foot. Clinical features vary; refer to documentation for location, laterality, and whether the ulcer is actively present.
When to use this code
Use I83.005 when the provider documents varicose veins of a lower extremity with an associated ulcer on the foot, and the side is not specified. It fits outpatient, inpatient, or wound-care records that clearly connect the ulcer to venous insufficiency. If the note identifies a different ulcer site or a different venous disorder, check documentation.
Do not use for
Do not use this code for varicose veins without an ulcer, or when the ulcer is not on the foot. If laterality is documented, use the more specific code instead.
Coding tip
Confirm that the ulcer is documented as venous-related and that “unspecified lower extremity” truly applies before assigning I83.005.
