ICD-10 Code I82.C – Embolism and thrombosis of internal jugular vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.C – Embolism and thrombosis of internal jugular vein
What it is
I82.C identifies a clot or embolus in the internal jugular vein. Use it when documentation specifies thrombosis or embolism involving this neck vein.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include neck pain, swelling, tenderness, or a palpable cord, but the diagnosis should be supported by imaging or clear provider assessment.
When to use this code
Use I82.C when the provider documents embolism, thrombosis, or thrombus of the internal jugular vein. It may appear in the setting of catheter-related thrombosis, infection, or another documented provoking factor. Code only what is specifically stated in the record.
Do not use for
Do not use this code for thrombosis in other veins, such as the subclavian, brachiocephalic, or femoral veins. If the record does not specify the internal jugular vein, check documentation.
Coding tip
Verify the anatomic site carefully; “jugular vein” alone may not be enough if the internal jugular vein is not clearly documented.
