For NPI, NYS Medicaid requires that all practitioners entered as attending providers be on file as affiliated with the facility submitting the claim. The affiliation is performed by using the web application available on emedny.org.

(NOTE: A batch method was also developed to accommodate facilities that have a large quantity of affiliations to report to NYS Medicaid. Providers may create and submit this batch to New York State Medicaid utilizing their current batch submission methods (example: eMedNY Exchange or FTP). Preparers will not have the ability to edit the batch once it has been successfully entered through the batch process. However, they will be able to delete records, via the web based application, even if the record was originally submitted in a batch).

Please see the list below of provider types affected.
