ICD-10 Code I83.209 – Varicose veins of unspecified lower extremity with both ulcer of unspecified site and inflammation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.209 – Varicose veins of unspecified lower extremity with both ulcer of unspecified site and inflammation
What it is
This code identifies varicose veins in an unspecified lower extremity when the veins are complicated by both an ulcer and inflammation. Use it when the record confirms venous disease with these two complications, but the exact leg or ulcer site is not specified.
Clinical signs
Typical documentation may note visible varicose veins, skin inflammation, and an ulcer related to venous insufficiency. Clinical features vary; refer to documentation for the affected extremity and whether the ulcer site is described.
When to use this code
Use this code when the provider documents varicose veins of a lower extremity with both ulceration and inflammation, and does not identify the side or site more specifically. It is appropriate for venous ulcer cases with inflammatory changes. Check documentation if the ulcer location or laterality is later clarified.
Do not use for
Do not use this code for varicose veins without ulcer or inflammation, or for ulcers from nonvenous causes. If the record specifies a different extremity, site, or complication pattern, select the more specific code.
Coding tip
Look for all three elements in the note: varicose veins, ulcer, and inflammation; if any are missing, code to the documented condition only.
