In simple words: This code indicates a sudden blockage in the deep veins of your arm, typically caused by a blood clot formed there or one that has traveled from another part of your body.

This code signifies the acute blockage of deep veins in the upper extremity due to a blood clot (thrombosis) or a piece of a clot that has traveled from elsewhere in the body (embolism).

Example 1: A patient presents to the emergency department with sudden swelling, pain, and bluish discoloration of the right arm. Ultrasound confirms the presence of deep vein thrombosis in the brachial vein., A patient with a peripherally inserted central catheter (PICC) line in the left arm develops arm swelling and pain.Doppler ultrasound reveals a thrombus in the axillary vein., A patient with a history of atrial fibrillation experiences sudden onset of pain and coldness in their left hand.Imaging studies identify an embolus lodged in the ulnar artery.

Documentation should clearly specify the location and laterality (right, left, or bilateral) of the deep vein thrombosis or embolism. Diagnostic imaging reports (e.g., ultrasound, venography) should be included to support the diagnosis.Documentation should also include clinical findings like swelling, pain, and discoloration, and any associated risk factors or underlying conditions.
