ICD-10 Code I83.00 – Varicose veins of unspecified lower extremity with ulcer (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.00 – Varicose veins of unspecified lower extremity with ulcer
What it is
This code identifies varicose veins in a lower extremity when the affected side is not specified and an ulcer is present. Use it when the record documents both venous varicosities and a lower-leg ulcer tied to that condition.
Clinical signs
Typical findings include visible, enlarged superficial veins and a chronic ulcer in the lower leg or ankle area. Clinical features vary; refer to documentation for laterality, ulcer location, and whether venous disease is the stated cause.
When to use this code
Use I83.00 when the provider documents varicose veins of an unspecified lower extremity with ulceration and does not identify the right or left leg. This is appropriate for outpatient, inpatient, or wound-care records that clearly link the ulcer to varicose veins. If the ulcer cause or laterality is unclear, check documentation before coding.
Do not use for
Do not use this code for varicose veins without ulcer, or for ulcers unrelated to venous disease. If the record specifies the right or left leg, use the laterality-specific code instead.
Coding tip
Confirm that the ulcer is documented as associated with varicose veins and that laterality is truly unspecified.
