ICD-10 Code I82.220 – Acute embolism and thrombosis of inferior vena cava (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.220 – Acute embolism and thrombosis of inferior vena cava
What it is
This code identifies an acute blood clot or embolus in the inferior vena cava, the large vein that returns blood from the lower body to the heart. Use it when the provider documents a new, active thrombotic event in that vessel.
Clinical signs
Clinical features vary; refer to documentation. Patients may have symptoms of venous obstruction, such as swelling, pain, or signs of impaired venous return, and imaging is often used to confirm the diagnosis.
When to use this code
Use I82.220 when the record specifically states acute embolism or thrombosis of the inferior vena cava. It fits confirmed IVC clotting documented by imaging, operative findings, or a clear provider assessment. If the note only mentions suspected clot or another vein location, check documentation.
Do not use for
Do not use this code for chronic, old, or resolved IVC thrombosis unless the provider states it is acute. It is also incorrect for thrombosis in a different vein, such as the femoral, iliac, or portal veins.
Coding tip
Verify that the provider names the inferior vena cava and the acute nature of the event before assigning I82.220.
