Unsp rider of mtrcy inj in clsn with hv veh in traf, subs

This diagnosis code indicates that an individual, whose specific role on the motorcycle is not detailed, sustained injuries in a traffic accident involving a heavy transport vehicle or bus. The encounter being documented is for follow-up care, rehabilitation, or management of complications after the initial treatment of these injuries.

This code is appropriate for documenting subsequent visits for a patient who was an unspecified motorcycle rider involved in a collision with a large commercial vehicle or bus. It should be used for ongoing care such as physical therapy, wound checks, or medication management related to the initial incident. Do not use for the initial treatment of the acute injuries.

• Ensure the documentation clearly states this is a subsequent encounter for injuries sustained in the specified type of accident.
• Verify that the patient was an unspecified rider on a motorcycle, not a driver or passenger, and the other vehicle was a heavy transport vehicle or bus.
• Always code the specific injuries sustained in addition to this external cause code.
