Unspecified transport accident, subsequent encounter

This code signifies a follow-up encounter for an injury sustained in a transport accident where the specific type of transport (e.g., car, bicycle, pedestrian) is not documented or is unknown. It indicates that the patient is receiving ongoing care for the sequelae of such an event.

Use this code when a patient presents for subsequent treatment, follow-up, or rehabilitation related to an injury from a transport accident, and the medical record does not specify the mode of transport involved. This is appropriate for encounters after the initial acute care phase.

• Always strive for a more specific transport accident code if documentation permits.
• This code requires a seventh character of 'D' for subsequent encounter.
• Pair this code with external cause codes (V00-V99) and injury codes (S00-T88) to fully describe the event and injury.
