Physician Payments Sunshine Act (Sunshine Act)

Signed into law in 2010 as part of the Affordable Care Act, the Physician Payments Sunshine Act (Sunshine Act) requires manufacturers, including certain distributors of medical devices, drugs, biologicals and medical supplies to track and report ownership interests as well as certain payments made to and transfers of value provided to physicians and teaching hospitals. Effective August 1, 2013, manufacturers were required to begin collecting information about payments, transfers of value and ownership interests and to submit these reports to the Centers for Medicare and Medicaid Services (CMS) on an annual basis. A payment or transfer of value must be reported when it is valued at $10 or more, or if valued at less than $10, when the sum of all items/payments/transfers of value given to a particular recipient over a year exceeds $100. The majority of the information contained in these reports will be available on a public, searchable website. Physicians will have the right to review their reports and challenge reports that are false, inaccurate or misleading.

Please note that exhibitors or other parties covered by the Sunshine Act may track and report items, meals or other transfers of value that they provide to you during Advocacy Day 2024 in accordance with their interpretation of the requirements set forth in the Sunshine Act and regulations.

View more information on the Sunshine Act and access the CMS website.

Security and Attendee Conduct Information

For security reasons, the Advocacy Day 2024 badge will be required for admittance to all events. Badges should be worn and visible at all times. Lost badges should be reported to the Registration staff immediately. The following badge policies will be in effect throughout the conference:

  1. Advocacy Day 2024 badges are the sole property of ASTRO.
  2. Badges are not transferable.
  3. False certification of individuals as Advocacy Day 2024 attendees, misuse of badges, any method of assisting unauthorized persons to gain access to any Advocacy Day 2024 event, or any inappropriate or unauthorized conduct will be just cause for repossessing the badge of any individuals involved and expelling all parties involved from the Meeting without obligation on the part of ASTRO for refund of any fees.

In addition, individuals who are part of Advocacy Day 2024 may not engage in any demonstrations or other behavior that ASTRO deems potentially disruptive to the conduct of the Meeting. Violation of this rule is grounds for immediate dismissal from the meeting and/or ineligibility for attendance at future ASTRO events.
