Occup of bus injured in clsn w nonmtr vehicle in traf, subs

This code describes an injury sustained by an unidentifiable passenger on a bus involved in a traffic accident with a non-motorized vehicle (e.g., bicycle, animal-drawn vehicle). The "subsequent encounter" designation indicates that the patient is receiving follow-up care for an injury that occurred at an earlier date.

This code is appropriate for documenting ongoing treatment, such as wound care, physical therapy, or medication management, for a patient previously diagnosed with injuries from this specific type of bus accident. It should be used after the initial acute phase of care has concluded.

• Ensure the documentation clearly specifies a bus occupant and a collision with a non-motor vehicle.
• Verify that the encounter is for follow-up care, not the initial treatment of the injury.
• Always code the specific nature of the injury (e.g., fracture, sprain) in addition to this external cause code.
