Assault by strike by baseball bat, initial encounter

This code describes an injury sustained as a direct result of an assault where a baseball bat was used as the weapon, and it is the first time the patient is being treated for this specific injury. The nature of the injury itself (e.g., fracture, contusion) would be coded separately.

Apply this code when documenting an external cause of injury resulting from an intentional act of violence involving a baseball bat. This is appropriate for initial treatment in an emergency department, urgent care, or primary care setting following such an assault.

• Always sequence this external cause code after the primary diagnosis code describing the actual injury.
• Ensure the documentation clearly states the injury was due to an "assault" and specifically mentions a "baseball bat."
• Verify that this is indeed the "initial encounter" for treatment of this specific injury; subsequent encounters would use different seventh characters.
