Prsn brd/alit hv veh injured in nonclsn trnsp accident, subs

This code signifies an injury sustained by an individual while getting on or off a large transport vehicle (e.g., bus, train, large truck) due to a non-collision event. It specifically applies to follow-up care for such an injury, indicating that the initial treatment has already been rendered.

Use this code for subsequent encounters when a patient presents for ongoing management of injuries, such as follow-up appointments for fractures, sprains, or contusions, that occurred while boarding or alighting a heavy transport vehicle without a collision. This includes scenarios like falls from steps, being caught in a closing door, or losing balance during entry/exit.

• Ensure the encounter is for follow-up care; initial encounters would use the 'A' seventh character.
• Verify the injury occurred during the act of boarding or alighting, not while the vehicle was in motion or during a collision.
• Confirm the vehicle involved meets the definition of a "heavy transport vehicle."
