Acute embolism and thrombosis of int jugular vein, bilateral

This code signifies the sudden blockage of both internal jugular veins by an embolus (traveling clot) or a thrombus (stationary clot). This condition can lead to significant venous congestion in the head and neck, potentially causing swelling, pain, and neurological symptoms.

Apply this code when documentation clearly indicates an acute, bilateral occlusion of the internal jugular veins due to either an embolism or thrombosis. Supporting documentation would include imaging reports (e.g., ultrasound, CT venography) confirming the bilateral nature and acuity of the occlusion, along with physician notes detailing the patient's symptoms and diagnosis.

• Ensure the documentation explicitly states "acute" and "bilateral" to support the specificity of this code.
• Distinguish from chronic or unilateral jugular vein thrombosis, which would be coded differently.
• Always code any underlying cause of the embolism or thrombosis (e.g., malignancy, hypercoagulable state) as an additional diagnosis.
