Pasngr on bus injured in nonclsn trnsp acc in traf, subs

This code describes an injury sustained by a passenger traveling on a bus involved in a traffic accident that did not involve a collision with another vehicle or object. The "subsequent encounter" designation indicates that the patient is receiving follow-up care for an injury initially treated in a prior encounter.

This code is appropriate for documenting ongoing treatment, such as physical therapy, wound care, or follow-up appointments, for a patient injured while a passenger on a bus during a non-collision traffic incident. Examples include injuries from sudden braking, swerving, or a passenger falling within the bus due to an abrupt maneuver, where the bus itself did not collide with anything.

• Ensure the documentation clearly states the patient was a passenger on a bus and the accident was a non-collision type in traffic.
• Verify that this is a subsequent encounter for the injury; initial treatment would use the "A" (initial encounter) seventh character.
• Always code the specific injury sustained by the patient in addition to this external cause code.
