You notice your neighbor's name on the schedule for an appointment today. Your neighbor is being seen for an initial workers' compensation claim due to a knee injury sustained at work. Last night you saw your neighbor in their yard push moving and raking leaves. Your neighbor appeared to be fine and was not wearing any braces or using assistive devices. When your neighbor comes in for the appointment, they are wearing a knee brace and using crutches. What would you do if you suspected that a patient was committing workers' compensation fraud? Would you notify anyone? Do you need to worry about HIPPA laws with this case? Explain your answer.
