Overpayments can occur for a multitude of reasons: an insurer may make a simple mistake and pay more than the contracted amount for a given service, or a healthcare provider may be paid for a service that isn’t covered by a patient’s plan. In either case, or in those alike, an insurance company is likely to ask for money back in attempt to correct their mistake. Therefore, you should not base your partnership with any of the above companies based on whether or not they’re more likely to ask for money back. You should, however, include these survey results in the information you review and consider.
