Occup of bus inj in clsn w nonmtr vehicle in traf, sequela

This code describes a long-term health condition or complication resulting from an injury sustained by an unspecified bus occupant in a traffic accident. The initial collision involved the bus and another non-motorized vehicle. The "sequela" designation indicates that the current encounter is for the residual effects of that past injury.

This code is appropriate when a patient presents for treatment of a chronic condition or complication directly attributable to an injury sustained as an unspecified occupant of a bus involved in a collision with a non-motor vehicle. This includes conditions like chronic pain, limited range of motion, neurological deficits, or other lasting impairments from the original accident. It should be used after the acute phase of the injury has passed.

• Always sequence the code for the specific sequela (e.g., chronic pain, fracture nonunion) first, followed by this external cause code.
• Ensure documentation clearly links the current condition to the past bus accident involving a non-motor vehicle.
• Verify that the patient's role as an "unspecified occupant" of the bus is supported by the medical record.
