ICD-10 Code I82.22 – Embolism and thrombosis of inferior vena cava (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.22 – Embolism and thrombosis of inferior vena cava
What it is
I82.22 identifies a 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 documentation specifically names this vessel.
Clinical signs
Clinical features vary; refer to documentation. Patients may have signs of venous obstruction, such as swelling, pain, or venous congestion, but the key requirement is documented thrombosis or embolism in the inferior vena cava.
When to use this code
Use this code when the provider documents embolism or thrombosis involving the inferior vena cava, including imaging-confirmed clot in that vessel. It may also apply when the note clearly states IVC thrombosis or IVC embolus. Check documentation for acuity and any associated conditions.
Do not use for
Do not use this code for thrombosis limited to the lower-extremity deep veins, portal system, or other vessels. If the record only says “venous thrombosis” without IVC involvement, check documentation.
Coding tip
Code I82.22 only when the inferior vena cava is named explicitly; otherwise, query or use the documented site.
