Almost six years after the law creating the basis for regulations, the Office of the Inspector General issued rules regarding voluntary repayments.  If a provider or supplier under Part A or B, receives an overpayment and does not return it within 60 days of identifying it, the claims convert to false claims and become available to whistleblowers and enforcers.  For physician practices in particular, the challenges in managing this process are considerable.  How to monitor, what is reasonable diligence, how to report, when to report and how and when to extrapolate from a sample are all issues to be confronted.  We think this is such an important issue for physician practices that we have published five separate articles about it with practical guidance, including Alice’s major chapter in the 2017 edition of the HEALTH LAW HANDBOOK. We also have presented a teleconference on the subject.
