Unspecified water transport accident, subsequent encounter

This code indicates that a patient is receiving follow-up care for injuries sustained in an unspecific water-related transportation incident. The initial treatment for the acute injury has already been completed, and the patient is now in the healing phase, requiring continued medical attention.

Apply this code when documenting subsequent encounters for conditions resulting from any type of water transport accident where the specific type of vessel or incident is not documented. This includes follow-up visits for rehabilitation, wound care, or monitoring of complications after the initial injury from an unclassified boat, ship, or other watercraft accident.

• Ensure documentation clearly states the encounter is for follow-up care, not the initial treatment.
• Only use this code when the specific type of water transport accident is unknown or not specified in the medical record.
• Always code the specific injury(ies) sustained in the accident first, followed by this external cause code.
