ICD-10 Code I82.C22 – Chronic embolism and thrombosis of left internal jugular vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.C22 – Chronic embolism and thrombosis of left internal jugular vein
What it is
This code identifies a long-standing blood clot or embolic obstruction in the left internal jugular vein. Use it when the record documents chronic thrombosis or chronic embolism at that specific neck vein site.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note neck swelling, pain, venous distention, or imaging evidence of persistent clot in the left internal jugular vein.
When to use this code
Use this code when the provider clearly documents chronic embolism or chronic thrombosis involving the left internal jugular vein. It is appropriate for follow-up visits, ongoing management, or imaging-confirmed chronic clot without a more specific alternate diagnosis.
If the note only says “history of clot” or does not identify chronicity and laterality, Check documentation. Code the condition only when the left internal jugular vein and chronic nature are both supported.
Do not use for
Do not use this code for acute thrombosis, unspecified jugular vein clot, or right-sided internal jugular vein disease. Check documentation if the record describes another venous site or no chronic diagnosis.
Coding tip
Verify both laterality and chronicity in the provider note or imaging report before assigning I82.C22.
