ICD-10 Code I83.011 – Varicose veins of right lower extremity with ulcer of thigh (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.011 – Varicose veins of right lower extremity with ulcer of thigh
What it is
This code identifies varicose veins in the right leg with an associated ulcer on the thigh. Use it when documentation links the ulcer to venous disease in the right lower extremity.
Clinical signs
Typical findings include visibly enlarged, tortuous veins and a chronic skin ulcer on the right thigh. Clinical features vary; refer to documentation for laterality and the ulcer’s venous cause.
When to use this code
Use I83.011 when the provider documents varicose veins of the right lower extremity and specifies an ulcer of the thigh. The record should support that the ulcer is part of the venous disease picture, not a separate traumatic or pressure-related wound.
If the ulcer site or laterality is unclear, check documentation before assigning the code. You should also confirm that the condition is not better described by a different venous ulcer code.
Do not use for
Do not use this code for varicose veins without an ulcer, or for ulcers of another cause. Check documentation if the ulcer is on a different leg location or if laterality is not stated.
Coding tip
Match the documented vein disease, laterality, and ulcer location exactly before coding.
