Activity, other involving water and watercraft

This code identifies an injury or adverse effect that occurred during participation in a water-related activity, excluding those specifically involving swimming, diving, or water sports. It encompasses a broad range of recreational or occupational activities performed in or around water, or involving watercraft. The focus is on the activity itself as the external cause of the injury.

Use this code when documenting an external cause of injury that occurred during activities such as fishing from a boat, canoeing, kayaking, paddleboarding, or general boating (e.g., motorboating, sailing) where the specific water sport codes do not apply. It is appropriate for incidents like falls from a dock, injuries sustained while launching a boat, or accidents during non-sporting water-based recreation.

• Always assign this code as a secondary diagnosis following the primary injury code.
• Ensure the medical record clearly documents the specific water-related activity that led to the injury.
• Differentiate from more specific water sport codes (e.g., Y93.11 for swimming, Y93.12 for diving) to ensure accurate reporting.
