ICD-10 Code I82.41 – Acute embolism and thrombosis of femoral vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.41 – Acute embolism and thrombosis of femoral vein
What it is
I82.41 identifies an acute blood clot or embolus in the femoral vein. Use it when documentation states acute thrombosis or embolism involving the femoral vein, usually as a form of deep vein thrombosis.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include unilateral leg swelling, pain, tenderness, warmth, or discoloration, with imaging used to confirm femoral vein involvement.
When to use this code
Use this code when the provider documents an acute embolism or thrombosis specifically in the femoral vein. It fits confirmed femoral deep vein thrombosis, whether described as embolic or thrombotic in origin. Check documentation if the clot location is broader or only suspected.
Do not use for
Do not use this code for chronic, old, or resolved femoral vein thrombosis. Do not use it when the clot is documented in another vein or when the record only says “history of DVT.”
Coding tip
Code the exact vein named in the record; if laterality or acuity is unclear, check documentation before assigning I82.41.
