Prsn brd/alit a car injured in collision w 2/3-whl mv, subs

This code signifies an injury sustained by an individual who was in the process of entering or exiting a car when it was involved in a collision with a motorcycle, moped, or motorized tricycle. The "D" suffix indicates that this is a subsequent encounter, meaning the patient is receiving follow-up care for an injury initially treated in a prior encounter.

This code is appropriate for documenting follow-up care for injuries sustained by a person boarding or alighting a car during an accident with a two- or three-wheeled motor vehicle. This includes situations like physical therapy, wound care, or medication management for injuries previously diagnosed and treated.

• Ensure the documentation clearly indicates the patient was boarding or alighting the car at the time of impact.
• Verify that the collision involved a two- or three-wheeled motor vehicle, not another type of vehicle.
• Confirm this is a subsequent encounter for the injury; for initial treatment, an "A" suffix would be used.
