ICD-10 Code I82.C11 – Acute embolism and thrombosis of right internal jugular vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.C11 – Acute embolism and thrombosis of right internal jugular vein
What it is
This code identifies a recent blood clot or embolus in the right internal jugular vein. Use it when documentation specifies the right side and the event is acute.
Clinical signs
Clinical features vary; refer to documentation. Findings may include neck pain, swelling, tenderness, or venous distention, with imaging used to confirm thrombosis or embolism in the right internal jugular vein.
When to use this code
Use I82.C11 when the record clearly states acute embolism or thrombosis of the right internal jugular vein. It is appropriate for confirmed venous clotting in that vessel, including imaging-based diagnoses. Check documentation if laterality or acuity is unclear.
Do not use for
Do not use this code for chronic thrombosis, unspecified jugular vein involvement, or left-sided disease. If the note does not specify acute right internal jugular involvement, check documentation.
Coding tip
Verify both acuity and laterality in the report before assigning I82.C11.
