Occup of hv veh injured in collision w oth mv in traf, subs

This code signifies a follow-up encounter for an unspecified individual who sustained injuries as an occupant of a large transport vehicle (e.g., bus, truck) involved in a collision with another motor vehicle on a public roadway. The specific type of heavy transport vehicle or the occupant's role within it (driver, passenger) is not documented.

This code is appropriate for subsequent visits related to injuries sustained in such an accident when the initial encounter has already been coded. It should be used when the medical record clearly indicates a heavy transport vehicle and another motor vehicle were involved, but further detail about the occupant's role or the vehicle type is missing.

• Ensure the encounter is for follow-up care, not the initial treatment.
• Confirm the documentation specifies a "heavy transport vehicle" and "other motor vehicles" in a traffic accident.
• Only use this code if the specific occupant role (e.g., driver, passenger) or the exact type of heavy transport vehicle is not documented.
