NPI Number Requested at the Annual Meeting

To help exhibitors and sponsors comply with new federal healthcare laws, AO is asking U.S. health care provider attendees to supply their 10-digit NPI (National Provider Identifier) number.

Beginning August 1, 2013, medical device and pharmaceutical companies are required by the Sunshine Act terms of the Patient Protection and Affordable Care Act to use this number to report any payment or other transfer of value (TOV) given to healthcare providers with a minimum value of $10/payment or $100/year to the Department of Health & Human Services (HHS). The Sunshine Act classifies TOV as, but not limited to, gifts, entertainment, certain meals, consulting fees, and honoraria.

If you have already provided your NPI number to the AO, it will automatically appear in your registration information. If you have not supplied this number, you can add it when you register.

This number will be part of the information embedded in your badge’s barcode but will not be printed on the badge.

NPI numbers are public information. If you do not know your NPI number, you can search for it by CLICKING HERE
