Machinery accident on board oth powered watercraft, subs

This code signifies an injury or adverse health effect resulting from an accident involving machinery on a motorized watercraft other than a ship or boat, such as a jet ski or personal watercraft. The "subsequent encounter" designation indicates that the patient is receiving follow-up care for an injury that occurred previously.

This code is appropriate for documenting ongoing treatment, such as wound care, physical therapy, or follow-up examinations, for injuries sustained in a machinery accident on a powered watercraft. Examples include a patient returning for a cast change after a propeller injury or for rehabilitation following an entanglement with engine components.

• Ensure the documentation clearly specifies the injury occurred on a powered watercraft other than a ship or boat.
• Verify that the encounter is for follow-up care, not the initial treatment of the injury.
• Always code the specific injury first, followed by this external cause code.
