Pasngr in hv veh inj in clsn w rail trn/veh nontraf, subs

This code describes injuries sustained by a passenger in a large transport vehicle (e.g., bus, truck) that collided with a train or other railway vehicle, occurring in a non-traffic setting. This specific code is for a subsequent encounter, meaning the patient is receiving follow-up care for injuries initially treated.

Use this code for patients presenting for ongoing treatment, such as wound care, physical therapy, or follow-up appointments, related to injuries from the described accident. The initial encounter for these injuries would have been coded with the "A" (initial encounter) seventh character.

• Ensure the patient was a passenger, not the driver, of the heavy transport vehicle.
• Verify the accident involved a collision with a railway train or vehicle and was not on a public roadway.
• Confirm this is a subsequent encounter for the injury, not the initial treatment.
