ICD-10 Code I82.413 – Acute embolism and thrombosis of femoral vein, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.413 – Acute embolism and thrombosis of femoral vein, bilateral
What it is
This code identifies an acute blood clot or embolus in both femoral veins, the large veins in the thighs. It is used when the condition is new or active and documented as bilateral.
Clinical signs
Common findings include thigh or leg swelling, pain, tenderness, warmth, or redness. Clinical features vary; refer to documentation, and confirm that the femoral veins on both sides are involved.
When to use this code
Use I82.413 when the provider documents acute thrombosis or embolism of the femoral vein on both sides. Apply it for imaging-confirmed bilateral femoral deep vein thrombosis or equivalent clear documentation. If the record does not specify acuity or laterality, check documentation.
Do not use for
Do not use this code for chronic, unspecified, or single-sided femoral vein thrombosis. Also avoid it if the clot is documented in another venous site only; verify the exact vein and laterality.
Coding tip
Confirm both acuity and bilateral femoral involvement in the note before assigning I82.413.
