Machinery accident on board oth powered watercraft, sequela

This code indicates a long-term health condition or complication resulting from an injury sustained due to a machinery accident on a powered watercraft other than a ship, such as a motorboat, yacht, or personal watercraft. The sequela could manifest as chronic pain, limited mobility, neurological deficits, or other lasting effects directly attributable to the original incident.

Use this code when documenting a patient presenting with a current health problem that is a direct consequence of a past machinery accident on a powered watercraft. This applies to follow-up visits, rehabilitation, or ongoing management of conditions that arose from the initial injury.

• Always sequence the code for the specific sequela (e.g., chronic pain, scar, nonunion fracture) first, followed by this external cause code.
• Ensure documentation clearly links the current condition to the past machinery accident on a powered watercraft.
• The "S" at the end indicates a sequela, meaning it should only be used for conditions that are residual effects of an earlier injury.
