Bus occupant (driver) (passenger) injured in unsp traf, subs

This code signifies that a driver or passenger of a bus sustained injuries in a traffic accident, and the specific circumstances or type of accident are not documented. It is used for encounters following the initial treatment of these injuries.

This code is appropriate for follow-up visits, rehabilitation sessions, or subsequent diagnostic tests for a bus occupant whose injuries resulted from an unclassified traffic collision. It should be applied when the initial encounter for the injury has already been coded.

• Requires a seventh character "D" for subsequent encounter.
• Only use when the type of traffic accident is truly unspecified in the medical record.
• Always sequence after the primary injury code(s).
