Person injured in collision betw car and bus, nontraf, subs

This code signifies an injury sustained by an individual involved in a collision between a car and a bus that occurred in a non-traffic environment. This includes incidents happening on private property, parking lots, or other areas not designated as public roadways. The "D" suffix indicates that this is a subsequent encounter for the injury, meaning the patient is receiving follow-up care after the initial treatment.

Use this code for patients presenting for follow-up care, such as wound checks, physical therapy, or medication adjustments, for injuries sustained in a car-bus collision that did not occur on a public highway or street. Examples include a patient returning for a cast change after being hit by a bus in a school parking lot, or a patient attending rehabilitation sessions after a car-bus incident on a private estate.

• Ensure the documentation clearly specifies a non-traffic incident to differentiate from traffic accidents.
• Verify the encounter is for subsequent care, not the initial treatment, which would require an "A" suffix.
• Always code the specific injury(ies) sustained in addition to this external cause code.
