2026 ICD-10-CM Diagnosis Code I82.411 – Acute embolism and thrombosis of right femoral vein
What it is
I82.411 identifies an acute blood clot in the right femoral vein. It is used when the clot blocks venous flow in that specific leg vein.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include unilateral leg pain, swelling, tenderness, warmth, or edema, with imaging confirming acute thrombosis in the right femoral vein.
When to use this code
Use this code when the provider documents an acute embolism and thrombosis limited to the right femoral vein. It fits confirmed deep vein thrombosis in that location, including cases found on ultrasound or other imaging. If the record does not specify the right side or acute status, check documentation.
Do not use for
Do not use I82.411 for chronic or historical venous thrombosis, or for thrombosis in another vein location. If the documentation is nonspecific or conflicts with the diagnosis, check documentation.
Coding tip
