Car passenger injured in collision w car in traf, subs

This code signifies a car passenger's injury sustained in a motor vehicle accident involving another car, occurring in a traffic setting. The "XD" extension indicates that this is a subsequent encounter for the injury, meaning the patient is receiving follow-up care after the initial treatment.

This code is appropriate for documenting ongoing treatment, rehabilitation, or follow-up visits for a car passenger injured in a two-car collision on a public roadway. It should be used after the initial encounter for the injury has been coded. Examples include physical therapy for whiplash or follow-up orthopedic appointments for a fracture sustained in such an accident.

• Ensure the patient was a passenger, not the driver, and the collision was with another car.
• Verify the encounter is for follow-up care, not the initial presentation of the injury.
• Always code the specific injury (e.g., fracture, sprain) first, followed by this external cause code.
