Struck by shark, initial encounter

This diagnosis code signifies an injury sustained from direct contact with a shark, where the shark is the active agent of the trauma. It specifically indicates the very first medical presentation or treatment for this particular shark-related injury.

Apply this code when documenting the initial assessment and treatment of a patient who has been bitten, struck, or otherwise injured by a shark. This includes emergency department visits, initial hospital admissions, or the first outpatient encounter for the injury.

• Always assign an external cause code (W56.42XA) in conjunction with a code describing the specific nature of the injury (e.g., laceration, puncture wound).
• Ensure the 7th character "A" is used only for the initial encounter for treatment of the injury.
• Consider additional external cause codes for place of occurrence (e.g., Y92.830 for ocean) and activity (e.g., Y93.11 for swimming).
