Acute embolism and thrombosis of right internal jugular vein

This code signifies the sudden blockage of the right internal jugular vein by an embolus (a traveling clot) or a thrombus (a clot formed in situ). This condition can lead to significant venous congestion and swelling in the head and neck region, potentially impacting cerebral venous drainage.

Use this code when documentation explicitly states an acute embolism or thrombosis affecting the right internal jugular vein. This typically occurs in patients presenting with acute onset of neck pain, swelling, or tenderness, often confirmed by imaging studies such as ultrasound or CT venography.

• Ensure the documentation specifies "acute" to differentiate from chronic conditions.
• Verify the laterality (right) and the specific vessel (internal jugular vein) are clearly stated.
• Do not confuse with thrombosis of other neck veins or chronic venous conditions.
