May 26, 2026
Starting Aug. 1, 2026, we’ll require new providers to submit a W-9 that includes both your legal name and Doing Business As Name, if applicable, as part of your onboarding application.
New providers also must submit required official IRS documentation such as SS-4 or 147C forms, or other official IRS notification of Tax ID Number assignment with your application.
Current in-network providers don’t need to submit an updated W-9, unless there has been an organizational change, such as a name or TIN change. If you need to update your legal or DBA name or TIN, submit your updated W-9 and official IRS documentation via a new provider onboarding application.
Out-of-network providers may submit organizational changes via the Demographic Change Form.
If you have questions, contact your network representative.
