ICD-10 Code I82.419 – Acute embolism and thrombosis of unspecified femoral vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.419 – Acute embolism and thrombosis of unspecified femoral vein
What it is
This code identifies an acute blood clot or embolus in a femoral vein when the affected side is not documented. Use it for a new, active clot in the thigh vein.
Clinical signs
Typical findings include unilateral leg swelling, pain, warmth, or tenderness, but clinical features vary; refer to documentation. Imaging confirmation of femoral vein thrombosis is commonly used.
When to use this code
Use I82.419 when the record states acute embolism and thrombosis of the femoral vein and does not specify left or right. It also fits cases where the provider documents an acute femoral DVT without laterality. Check documentation if the note describes chronic, recurrent, or another venous site.
Do not use for
Do not use this code for chronic thrombosis, superficial vein thrombosis, or DVT in a different vein location. If the side is documented, choose the laterality-specific code instead.
Coding tip
Confirm that “acute” and “unspecified femoral vein” are both documented before assigning I82.419.
