ICD-10 Code I82.211 – Chronic embolism and thrombosis of superior vena cava (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.211 – Chronic embolism and thrombosis of superior vena cava
What it is
This code identifies a long-standing clot or embolic obstruction in the superior vena cava, the large vein that returns blood from the upper body to the heart. Use it when the condition is documented as chronic.
Clinical signs
Clinical features may include swelling of the face, neck, or upper extremities, visible chest wall veins, and symptoms related to impaired venous return. Clinical features vary; refer to documentation.
When to use this code
Use I82.211 when the provider documents chronic thrombosis or chronic embolism involving the superior vena cava. It may also apply when imaging or specialist notes confirm an established, non-acute SVC clot. If the record only says “SVC obstruction,” check documentation.
Do not use for
Do not use this code for acute superior vena cava thrombosis, unspecified venous thrombosis, or external compression without a clot. Check documentation if the cause is uncertain.
Coding tip
Confirm the chronicity and the exact vessel site before coding, because superior vena cava thrombosis is not the same as generic upper-extremity or central venous thrombosis.
