Person injured in clsn betw mtr veh and 2/3-whl mv, subs

This code signifies a patient presenting for follow-up care or management of injuries sustained in a traffic accident. Specifically, the collision involved another motor vehicle and a two- or three-wheeled vehicle (e.g., motorcycle, scooter, moped). The "subsequent encounter" indicates that the initial treatment for the acute injury has already been provided.

This code is appropriate for office visits, hospital readmissions, or therapy sessions related to the ongoing care of injuries from such an accident. Examples include follow-up appointments for fracture management, wound checks, physical therapy, or pain management after the initial acute phase. It should be used when the patient is no longer in the immediate, acute phase of injury.

• Ensure the documentation clearly indicates a "subsequent encounter" for the injury, not an initial presentation.
• Verify that the collision involved another motor vehicle and a two- or three-wheeled vehicle in a traffic setting.
• Always code the specific injury(ies) first, with this external cause code as a secondary diagnosis.
