Person injured wh brd/alit from military vehicle, subs

This code indicates that a patient sustained an injury during the act of getting on or off a military vehicle, and this encounter is for follow-up care after the initial treatment. The injury itself could be varied, but the key element is the mechanism of injury involving a military vehicle during boarding or alighting.

Use this code for subsequent visits related to an injury that occurred when a person was either entering or exiting a military vehicle. This includes follow-up appointments for wound checks, physical therapy, cast changes, or medication refills for injuries sustained in such an event.

• Always pair this external cause code with a primary diagnosis code describing the specific injury.
• Ensure the encounter is indeed "subsequent" and not the initial treatment for the injury.
• Verify the vehicle involved was specifically a military vehicle, not a civilian or other type of transport.
