Person injured in unsp motor-vehicle accident, traffic, subs

This code signifies an individual who sustained injuries in a motor vehicle accident of an unknown type, occurring on a public highway or road, and is now presenting for follow-up care or treatment after the initial encounter. The specific vehicle involved in the accident is not documented.

Apply this code when a patient is seen for ongoing treatment, rehabilitation, or complications related to injuries sustained in a traffic-related motor vehicle accident where the type of vehicle involved is not specified in the medical record. This is appropriate for subsequent visits after the initial assessment and treatment.

• Ensure the encounter is clearly documented as "subsequent" or for follow-up care.
• Only use when the type of motor vehicle involved in the accident is truly unspecified.
• Always sequence this external cause code after the primary diagnosis code(s) for the injuries sustained.
