ICD-10 Code I82.210 – Acute embolism and thrombosis of superior vena cava (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.210 – Acute embolism and thrombosis of superior vena cava
What it is
This code identifies an acute blood clot or embolus obstructing the superior vena cava. It applies when the blockage is in the large vein returning blood from the upper body to the heart.
Clinical signs
Clinical features may include swelling of the face, neck, or upper extremities, visible chest wall veins, and shortness of breath. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents an acute thrombosis or embolism specifically in the superior vena cava. It is appropriate when imaging or clinical assessment confirms the location and acuity. If the note only states “venous thrombosis” without site, check documentation.
Do not use for
Do not use this code for chronic, old, or resolved thrombosis, or for clots in other veins such as the lower extremities. Check documentation if the record does not clearly identify the superior vena cava.
Coding tip
Confirm both acuity and exact vessel location in the provider note before assigning I82.210.
