Occ of rail trn/veh inj in derail w/o antecedent clsn, init

This code describes injuries sustained by an individual who was a passenger or crew member on a train or other railway vehicle that left its tracks. The derailment occurred without first colliding with another object or vehicle. This specific code is for the initial treatment of the injury.

Apply this code when documenting the initial medical care for a patient injured as an occupant of a train that derailed, and the derailment was not preceded by a collision. Examples include a train overturning due to excessive speed, track malfunction, or mechanical failure, where no other vehicle or object was struck beforehand.

• Ensure the documentation clearly states the patient was an occupant of the railway vehicle and that the incident was a derailment without an antecedent collision.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Always code the specific injury(ies) sustained by the patient in addition to this external cause code.
