Acute embolism and thrombosis of axillary vein, bilateral

This diagnosis code signifies the sudden onset of a blood clot obstructing blood flow in both axillary veins. This condition is typically characterized by acute pain, swelling, and discoloration in both upper extremities, often developing rapidly. It represents an urgent medical situation requiring prompt diagnosis and intervention.

Apply this code when documentation explicitly states an acute embolism or thrombosis affecting both axillary veins. This typically occurs in the context of Paget-Schroetter syndrome (effort thrombosis), central venous catheter complications, or hypercoagulable states. Supporting documentation should include imaging reports (e.g., ultrasound, venography) confirming bilateral axillary vein occlusion and a clear indication of acute onset.

• Ensure documentation specifies "acute" to differentiate from chronic conditions.
• Verify laterality; this code is specifically for bilateral involvement. Do not use if only one axillary vein is affected.
• Consider additional codes for underlying causes (e.g., hypercoagulable state, malignancy) or associated complications.
