Car pasngr injured in nonclsn trnsp accident nontraf, subs

This code signifies a car passenger's injury sustained during a non-collision transportation incident that occurred off a public roadway. The "subsequent encounter" indicates that this code is used for follow-up care after the initial treatment for the injury.

This code is appropriate for documenting ongoing care, such as physical therapy, wound checks, or medication management, for a passenger injured in a private driveway, parking lot, or other non-traffic area when the vehicle did not collide with another object or vehicle. Examples include injuries from sudden braking, swerving to avoid an animal, or a door closing improperly, all occurring off a public road.

• Ensure the documentation clearly specifies "car passenger" and "noncollision" in a "nontraffic" setting.
• Verify that the encounter is for follow-up care, not the initial treatment of the injury.
• Always code the specific nature of the injury (e.g., fracture, sprain) first, followed by this external cause code.
