Chronic embolism and thrombosis of r int jugular vein

This code signifies the persistent presence of a blood clot (thrombus) or an embolus within the right internal jugular vein. This chronic obstruction can impede venous blood flow from the head and neck, potentially leading to symptoms such as swelling, pain, or venous hypertension in the affected area.

Apply this code when documentation explicitly states a chronic embolism or thrombosis affecting the right internal jugular vein. This typically follows a diagnosis confirmed by imaging studies such as ultrasound, CT venography, or MRI, and when the condition is not acute.

• Ensure documentation specifies "chronic" to differentiate from acute events.
• Laterality (right) is crucial for accurate code selection; do not use if the left or unspecified jugular vein is involved.
• Distinguish from phlebitis or thrombophlebitis without documented chronic occlusion.
