Acute embolism and thrombosis of right subclavian vein

This code signifies the sudden blockage of the right subclavian vein by an embolus (a traveling clot) or a thrombus (a clot formed in situ). This condition leads to impaired blood flow from the right arm and head, potentially causing swelling, pain, and discoloration of the affected extremity. It is an acute event, indicating a recent onset.

This code is appropriate when documentation clearly indicates an acute, recently formed blood clot obstructing the right subclavian vein. Clinical scenarios include patients presenting with sudden onset of right upper extremity swelling, pain, and cyanosis, with diagnostic imaging (e.g., ultrasound, venography) confirming an acute embolism or thrombosis in the specified vein.

• Ensure documentation specifies "acute" and "right subclavian vein" to support this precise code.
• Distinguish from chronic thrombosis, which would require a different code.
• Consider sequencing with codes for underlying causes (e.g., malignancy, central venous catheter complications) if applicable.
