Tax identification number (TIN)
You don’t need to fill out a new application if you’re:
- An existing contracted provider updating your tax ID number (TIN)
- Adding another location under a different TIN
Just complete these steps:
- Send us a letter (on company letterhead) with details of the TIN change request. You can email us. Or you can fax us: 1-844-235-1340. Include your name and service location info.
- Include a copy of the new W-9, if applicable. If you’re contracted as a group, send a group W-9. Otherwise, just send an individual W-9.
After you send us your materials and information, we’ll process the change or contact you for more details.
If you don’t receive a confirmation email for the change, contact your network consultant. Check this provider relations contact list (PDF) to learn more.
