Pasngr in hv veh injured in clsn w hv veh in traf, sequela

This code signifies a long-term or late-developing health condition resulting from a traffic accident where the patient was a passenger in a large transport vehicle (e.g., truck, bus) that collided with another heavy transport vehicle or bus. The initial injury has resolved, but the patient is now experiencing a residual effect directly attributable to that specific motor vehicle crash.

Use this code when documenting a sequela, such as chronic pain, neurological deficits, or psychological conditions, that is a direct consequence of a past collision between two heavy transport vehicles, and the patient was a passenger. This code is appropriate for follow-up encounters addressing these persistent issues, long after the acute injury phase has passed.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, scar, paralysis).
• Ensure documentation clearly links the current condition to the original heavy transport vehicle collision.
• Verify the patient's role as a "passenger" and the involvement of "heavy transport vehicles" in the original accident.
