Rider of nonpowr wtrcrft struck by oth nonpowr wtrcrft, init

This code describes injuries sustained by an individual riding a non-motorized watercraft (e.g., kayak, canoe, paddleboard) when it collides with another non-motorized watercraft. The encounter is the initial treatment for these injuries.

Apply this code when a patient presents for the first time with injuries resulting from a collision between two non-motorized watercraft, where the patient was operating one of them. This would include scenarios like a kayaker being hit by a rowboat or a paddleboarder colliding with a canoe.

• Always sequence this external cause code after the primary injury code(s).
• Ensure the "A" seventh character is used only for the initial encounter for treatment.
• Distinguish this from incidents involving powered watercraft or fixed objects.
