Ped w convey injured in collision w hv veh, unsp, subs

This code signifies a follow-up encounter for a pedestrian who sustained injuries after being struck by a heavy transport vehicle or bus while also using another conveyance (e.g., skateboard, scooter, rollerblades). The initial incident's traffic or nontraffic nature is not specified.

Apply this code for subsequent visits related to injuries sustained in such an accident, such as follow-up appointments for fracture care, wound checks, or physical therapy. It is appropriate when the documentation confirms the patient was a pedestrian using another conveyance and was involved in a collision with a large transport vehicle or bus.

• Always use a primary injury code in conjunction with this external cause code.
• Ensure documentation specifies "subsequent encounter" for this specific external cause.
• Verify the patient was a pedestrian utilizing another conveyance, not just a pedestrian.
