Injury to unspecified blood vessel of upper extremity

This code signifies an injury to a blood vessel within the upper limb (arm, forearm, or hand) where the specific vessel (e.g., artery, vein, capillary) is not documented. It indicates trauma to the vascular system of the upper extremity without further anatomical or type-of-vessel specificity.

This code is appropriate when documentation clearly states an upper extremity blood vessel injury, but lacks detail regarding the specific vessel or type of vessel involved. Examples include "vascular injury to the left arm" or "blood vessel trauma, right forearm" without further clarification. Use this code when more specific ICD-9 codes for named vessels or arterial/venous injuries cannot be supported by the medical record.

• Avoid using this code if the documentation specifies an artery (e.g., brachial artery) or vein (e.g., cephalic vein) injury; more specific codes exist.
• Always query the provider for greater specificity regarding the injured vessel if possible, to allow for more precise coding.
• Ensure the documentation confirms the injury is traumatic in nature, as this code is for injuries, not intrinsic vascular diseases.
