Injury to other specified blood vessels of upper extremity

This code signifies damage to blood vessels in the upper limb, excluding major arteries like the brachial, radial, or ulnar, and major veins like the subclavian or axillary. It encompasses injuries to smaller, named blood vessels or those not otherwise specified within the upper extremity.

Use this code for traumatic injuries such as lacerations, punctures, or contusions affecting specific, but not major, arteries or veins of the arm, forearm, or hand. Documentation should clearly identify the injured blood vessel (e.g., interosseous artery, digital vein) and its location within the upper extremity.

• Ensure the documentation specifies "other specified" blood vessels; avoid using for major named vessels.
• Always code the underlying cause of the injury (e.g., open wound, fracture) first, followed by this code.
• Do not use if the injury is to an unspecified blood vessel; a more general code would be appropriate in that case.
