Take timely corrective action if you discover an overpayment. Did you know that you're obligated to refund overpayments to payers regardless of primary-versus-secondary issues between the payers? If not, it's time for a refresher in how to navigate the often convoluted path to accurate primary-secondary payer claims. Beware Stay Compliant Both the OIG's compliance guidance for physicians and its guidance for third-party billing companies address overpayment refunding. As a healthcare provider, you have a legal obligation to repay any discovered overpayments. If you discover an overpayment, your practice should be prepared to refund one of the payers -- or sometimes the patient -- the money due. Pointer: If a patient presents you with information on what she thinks is her primary insurance, and your practice finds out much later that it was her secondary insurance but you were paid, talk with the payer. Ideally: Reality: Be Proactive If you find out about the error -- for example, if the patient calls your office several months later and explains the situation -- you should call the payer and let it know of the error. Often the payer may not do anything because so much time has passed, or it may work directly with the patient to solve the problem. "Contact should be made with the overpaying insurance, first, to identify what happened to create the overpayment; then a refund should be initiated as per instructions from the insurance company," says Linda Huckaby, CMA (AAMA), with Carolina Medical Rehabilitation in Greenville, S.C.
