Acute embolism and thrombosis of subclavian vein, bilateral

This code signifies the sudden blockage of both subclavian veins by an embolus (a traveling clot) or a thrombus (a stationary clot). This condition leads to impaired blood flow from the arms, potentially causing swelling, pain, and discoloration in the upper extremities.

Apply this code when documentation explicitly states an acute (sudden onset) embolism or thrombosis affecting both the left and right subclavian veins. Supporting documentation would include imaging reports (e.g., ultrasound, venography) confirming the bilateral nature and acuity of the venous occlusion.

• Ensure documentation specifies "acute" and "bilateral" for the subclavian veins; otherwise, a more general or unilateral code may be appropriate.
• Distinguish between acute and chronic conditions; chronic thrombosis of the subclavian vein has a different code.
• Always review imaging reports and physician notes for laterality and acuity to ensure accurate code assignment.
