Occupant (driver) of hv veh injured in unsp traf, subs

This code signifies that a driver or passenger of a large transport vehicle, such as a bus or truck, sustained injuries in a traffic accident where the specific type of accident is not documented. The "D" seventh character indicates that this is a subsequent encounter, meaning the patient is receiving follow-up care for injuries sustained in the initial event.

Use this code for patients presenting for ongoing treatment, such as wound care, physical therapy, or follow-up appointments, related to injuries from an unspecified motor vehicle accident involving a heavy transport vehicle. This applies when the initial injury has already been coded and the patient is no longer in the acute phase of care.

• Ensure documentation clearly states the patient was an occupant (driver or passenger) of a heavy transport vehicle.
• Only use the "D" seventh character for subsequent encounters; "A" is for initial encounters and "S" for sequela.
• Always code the specific injuries sustained in the accident in addition to this external cause code.
