ICD-10 Code I83.819 – Varicose veins of unspecified lower extremity with pain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.819 – Varicose veins of unspecified lower extremity with pain
What it is
This code identifies varicose veins in a lower extremity when the affected side is not documented and pain is present. It is used for symptomatic venous enlargement, not for simple cosmetic vein changes.
Clinical signs
Typical findings include visibly enlarged, twisted superficial veins with leg aching, heaviness, or discomfort. Clinical features vary; refer to documentation.
When to use this code
Use I83.819 when the record states varicose veins of a lower extremity and specifically documents pain, but does not specify right or left. Apply it when the note supports symptomatic venous disease rather than incidental varicosities. Check documentation if the laterality is available.
Do not use for
Do not use this code if the provider documents a specific leg, because a laterality-specific code is more accurate. Avoid it for spider veins, edema without varicose veins, or pain with no documented varicose veins.
Coding tip
Code the laterality first whenever the chart clearly identifies the affected leg.
