Committed to Transparency
At Genzyme we are focused on making a difference in patients’ lives. To make tomorrow’s therapeutic solutions real, we seek to innovate with other individuals and organizations, who like us, aim to improve patient health. We work with physicians and teaching hospitals as well as patient associations and others involved in healthcare. We are fully committed to transparency; it is important to us to foster an understanding of these interactions and to prevent any real or perceived conflict of interest. As part of the federal Open Payments (Physician Payments Sunshine Act), overseen by the Centers for Medicare and Medicaid Services (CMS) any payment or transfer of value we make to a physician or teaching hospital is subject to collection and potential public reporting. These payments are separate and in addition to existing state transparency reporting requirements. We continue to be dedicated to complying with state and federal laws and regulations today and in the future.
