The reprimand, which was first reported by DukeCheck, became effective on March 6. In it, the Missouri State Board of Registration for the Healing Arts noted that the North Carolina medical board had reprimanded Potti in November after he had
committed unprofessional conduct in that he had inaccuracies in his curriculum vitae and there were questions raised about possible misconduct involving his research work
Potti, who recently left a South Carolina oncology practice following a 60 Minutes investigation into his work, obtained his Missouri license on February 1, 2011. He continues to hold licenses in North Carolina and South Carolina. There was recently some short-lived confusion in the latter over the status of his ability to practice medicine because of a clerical error. He allowed a Minnesota license to expire in 2008.
