Laceration of radial artery at wrs/hnd lv of unsp arm, init

This code signifies a tear or cut in the radial artery, located in the wrist or hand region. This injury involves the primary blood vessel supplying the thumb side of the forearm and hand, and the "initial encounter" indicates the patient is receiving active treatment for the acute injury.

Apply this code for patients presenting with a fresh laceration to the radial artery in the wrist or hand, such as from a penetrating injury, deep cut, or trauma. It is appropriate when the patient is first seen for evaluation and management of this specific arterial injury.

• Ensure documentation specifies the radial artery and its location at the wrist/hand level.
• Confirm the encounter is for the initial treatment of the injury, not a follow-up or sequela.
• Always code laterality (left or right) if specified in the medical record; "unspecified arm" should only be used when laterality is truly unknown.
