Struck by tennis racquet, initial encounter

This code signifies an injury sustained from being hit by a tennis racquet. It indicates the patient's first presentation for this specific injury, which could range from minor contusions to more severe trauma. The impact can occur during active play, practice, or even accidentally outside of a game.

Apply this code when a patient presents for initial treatment of an injury directly caused by being struck by a tennis racquet. This includes scenarios where a player is hit by their own racquet, an opponent's racquet, or a racquet being swung by another individual. It is appropriate for the first visit related to the incident.

• Always assign an external cause code (W21.12XA) in conjunction with a code for the actual injury sustained (e.g., S00.81XA for contusion of other part of head).
• Ensure the 7th character "A" is used for the initial encounter, indicating the patient is receiving active treatment for the injury.
• Distinguish from injuries caused by being struck by a tennis ball (W21.01XA) or other sports equipment.
