Prsn brd/alit a car injured in collision w hv veh, 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 large commercial vehicle or bus. The "D" seventh character indicates that this is a subsequent encounter for care after the initial treatment of the injury.

This code is appropriate for follow-up visits, such as wound care, physical therapy, or medication management, for a patient injured while boarding or alighting a car during an accident with a heavy transport vehicle or bus. It should be used when the patient is receiving routine care during the healing or recovery phase of the injury.

• Ensure the documentation clearly specifies the patient was boarding or alighting a car and not another type of vehicle.
• Verify that the collision involved a heavy transport vehicle or bus.
• Confirm this is a subsequent encounter for treatment of the injury, not the initial presentation.
