Passenger on bus injured in collision w oth mv nontraf, subs

This code signifies a patient who was a passenger on a bus and sustained injuries in a collision with other motor vehicles, occurring in a non-traffic setting (e.g., parking lot, private property). This specific encounter represents a follow-up visit for the previously sustained injuries, not the initial presentation.

Use this code for subsequent treatment of injuries sustained by a bus passenger involved in a multi-vehicle collision that did not occur on a public roadway. Examples include follow-up appointments for fracture management, wound care, or physical therapy related to the original incident.

• Ensure the encounter is for follow-up care, not the initial injury assessment.
• Verify the accident occurred in a "nontraffic" environment, such as a private lot or driveway.
• Always code the specific injury(s) sustained in addition to this external cause code.
