May 15 is the last day to review and, if necessary, dispute data submitted by drug and device manufacturers detailing payments they made to physicians in 2015 as required under the Open Payments program. Open Payments is a national transparency program aimed at spotlighting financial relationships between physicians, teaching hospitals, and drug and device manufacturers. As previously reported, the review and dispute period opened on April 1, and is the only opportunity physician practices have to review and dispute payments and other transfers of value reported by drug and device manufacturers before the information is published on the Centers for Medicare & Medicaid Services Open Payments website. For more information, including instructions on how to access your practice's Open Payments data, download MGMA's comprehensive member resource, The Physician Open Payments Program: What You Need to Know.
