ICD-10 Code I82.C13 – Acute embolism and thrombosis of internal jugular vein, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.C13 – Acute embolism and thrombosis of internal jugular vein, bilateral
What it is
This code identifies an acute clot or embolus affecting both internal jugular veins. It means the obstruction is new or recently developed and involves the deep neck veins on both sides.
Clinical signs
Clinical features vary; refer to documentation. Patients may have neck pain, swelling, tenderness, or a palpable cord, and imaging is usually used to confirm bilateral internal jugular vein thrombosis.
When to use this code
Use this code when the provider documents acute thrombosis or embolism in both internal jugular veins. It also fits confirmed bilateral jugular vein clotting reported on imaging or in the final diagnosis. Check documentation if laterality or acuity is unclear.
Do not use for
Do not use it for chronic, old, or unspecified jugular vein thrombosis. Do not assign it when the clot is in a different vein or when only one side is documented.
Coding tip
Confirm both acuity and bilateral involvement in the record before coding I82.C13.
