ICD-10 Code I82.C2 – Chronic embolism and thrombosis of internal jugular vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.C2 – Chronic embolism and thrombosis of internal jugular vein
What it is
This code identifies a chronic clot or embolic obstruction in the internal jugular vein. Use it when the record clearly states a long-standing thrombosis or embolism in that neck vein.
Clinical signs
Clinical features vary; refer to documentation. Patients may have neck swelling, pain, venous distention, or findings on imaging confirming chronic internal jugular vein obstruction.
When to use this code
Use I82.C2 when the clinician documents chronic embolism or thrombosis of the internal jugular vein, including follow-up visits for an established condition. It also fits when imaging or specialist notes confirm the chronic nature and site. Check documentation if acuity or vein location is unclear.
Do not use for
Do not use this code for acute jugular thrombosis, suspected clot without confirmation, or thrombosis in another vein. If the record only says “venous thrombosis” without site, check documentation.
Coding tip
Verify both chronicity and the internal jugular vein location before assigning I82.C2.
