Prsn brd/alit a 3-whl mv inj in clsn w nonmtr vehicle, subs

This code describes an injury sustained by an individual who was in the process of getting on or off a three-wheeled motor vehicle when it collided with a non-motorized vehicle (e.g., bicycle, animal-drawn vehicle). This specific code indicates that the patient is receiving follow-up care for the initial injury, rather than presenting for the first time.

Use this code for subsequent encounters when a patient is being treated for complications, healing, or recovery from injuries sustained in such an accident. This includes follow-up appointments for wound care, physical therapy, or monitoring of fractures. It is appropriate when the initial acute care has already been provided and coded.

• Ensure the "D" seventh character is used only for subsequent encounters, not initial treatment.
• Always code the specific injury(ies) sustained in addition to this external cause code.
• Verify that the patient was indeed boarding or alighting the three-wheeled vehicle at the time of impact.
