Updating bulk amounts of servicing-only providers that already exist in ProviderOne

Bulk modifications for existing HCA servicing-only providers can be uploaded to ProviderOne using the roster spreadsheet.

To determine whether your group or facility can use the bulk modification capability, review the roster instructions for HCA providers only. If your group or facility meets the criteria listed, follow the instructions to complete a roster spreadsheet.

Once the roster spreadsheet has been completed, use the instructions for roster file upload and reviewing roster errors to upload the roster and resolve errors. (Find help for troubleshooting roster error messages.)
