ICD-10 Code I83.10 – Varicose veins of unspecified lower extremity with inflammation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.10 – Varicose veins of unspecified lower extremity with inflammation
What it is
This code identifies varicose veins in a lower extremity when the affected leg is not specified and inflammation is documented. Use it for chronic venous vein enlargement with inflammatory changes, not for uncomplicated varicosities.
Clinical signs
Typical findings include visibly enlarged, twisted superficial veins and local signs of inflammation such as tenderness, redness, or swelling. Clinical features vary; refer to documentation.
When to use this code
Use I83.10 when the record states varicose veins of a lower limb with inflammation but does not identify the right or left side. It also fits notes describing inflamed varicosities, superficial phlebitic changes, or similar language without a more specific laterality.
Do not use for
Do not use this code for varicose veins without inflammation, or when the documentation specifies a different lower-extremity site or laterality. Check documentation if the note instead describes deep vein disease or another vascular disorder.
Coding tip
If the provider names the side, code the laterality-specific option instead of this unspecified code.
