Occup of 3-whl mv injured in clsn w hv veh nontraf, sequela

This code signifies a long-term consequence or complication arising from an injury sustained by an unknown individual riding a three-wheeled motor vehicle. The original incident involved a collision with a large transport vehicle (like a truck or bus) and occurred outside of a public roadway, such as on private property or in a parking lot. The "sequela" indicates that the current encounter is for treatment of a residual condition from that past injury.

Apply this code when a patient presents for follow-up care, rehabilitation, or management of a chronic condition directly resulting from a past injury matching the described circumstances. This would include scenarios where the initial acute injury has healed, but the patient continues to experience related issues such as chronic pain, limited mobility, or neurological deficits. The specific occupant (driver, passenger) is not documented.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, scar contracture).
• Ensure documentation clearly links the current condition to the past three-wheeled vehicle accident with a heavy transport vehicle in a non-traffic setting.
• Verify that the encounter is for a sequela and not for the initial acute injury or a subsequent acute complication.
