Person injured wh brd/alit from special agri vehicle, subs

This code indicates an injury sustained by an individual during the act of getting on or off a specialized vehicle used in agriculture. The "D" seventh character signifies that this is a subsequent encounter for the injury, meaning the patient is receiving follow-up care after the initial treatment.

This code is appropriate for documenting follow-up visits for injuries such as sprains, fractures, or contusions that occurred while a person was boarding or alighting from farm machinery like tractors, combines, or harvesters. It should be used when the patient is seen for continued treatment, healing, or complications related to the initial incident.

• Ensure the documentation clearly states the injury occurred during the boarding or alighting process of an agricultural vehicle.
• Verify that the encounter is for follow-up care, not the initial treatment, to correctly apply the "D" seventh character.
• Always code the specific injury first, followed by this external cause code to provide full context.
