Physicians and teaching hospitals may review and dispute 2015 payments reported to the Open Payments program for a 45-day period that began April 1, the Centers for Medicare & Medicaid Services reports. Applicable drug and medical device makers and group purchasing organizations must annually report certain payments made to physicians and teaching hospitals, who may review and dispute inaccuracies for 45 days. The manufacturers and GPOs then have 15 days to resolve and submit corrections. Disputed data that is not resolved in the 15-day period will be publicly reported June 30 on the Open Payments website but marked as disputed. Physicians and teaching hospitals can continue to register and initiate disputes after the 45-day review period, but resolutions will not be publicly displayed until the next reporting cycle. To review data, physicians and teaching hospitals must be registered to use both the Open Payments system and CMS Enterprise Portal. For more on the review and dispute process, visit www.cms.gov.
