Occup of hv veh injured in clsn w unsp mv in traf, sequela

This code describes a delayed or residual health problem resulting from a traffic accident where an individual, whose specific role in the vehicle is unknown, was in a large transport vehicle that collided with another unspecified motor vehicle. The injury or condition being coded is a long-term consequence of this original incident.

Apply this code when documenting a sequela (e.g., chronic pain, scar, limited range of motion) stemming from a past motor vehicle accident involving a heavy transport vehicle and another motor vehicle, and the specific occupant role or type of other vehicle is not detailed in the medical record. This is appropriate when the initial injury has healed, but its lasting effects are being treated.

• Ensure the documentation clearly states the condition is a sequela of a past MVA.
• Only use this code when the specific occupant role (e.g., driver, passenger) and the type of other vehicle are truly unspecified.
• Always code the specific nature of the sequela (e.g., chronic headache, post-traumatic arthritis) first, followed by this external cause code.
