Prsn brd/alit a 3-whl mv injured in nonclsn trnsp acc, subs

This code signifies an injury sustained by an individual who was either getting on or off a three-wheeled motor vehicle when a non-collision transport accident occurred. The "subsequent encounter" designation indicates that this code is used for follow-up care after the initial treatment of the injury.

This code is appropriate for documenting ongoing care, such as wound checks, physical therapy, or medication adjustments, for a patient previously treated for an injury sustained while boarding or alighting a three-wheeled motor vehicle in a non-collision incident. Examples include injuries from falling off the vehicle while dismounting or being struck by a part of the vehicle during boarding, where no other vehicle was involved.

• Ensure the documentation clearly states the patient was boarding or alighting a three-wheeled motor vehicle at the time of the non-collision accident.
• Verify that this is not the initial encounter for the injury; otherwise, a different seventh character (A) would be appropriate.
• Always code the specific injury sustained in addition to this external cause code.
