Anthem California now requires a W9 file in order to verify the identity of your practice to process out or network claims.

Having a copy of your W9 on file with Reimbursify will reduce delays in getting claims processed. Click here to generate a W9 form that you can sign and send to us

Reimbursify will keep this W9 on file to submit to Anthem California and any other insurance companies that your clients may submit their claims to when they request it.

It is important to ensure the information on the W9 is current and up to date and that it matches what is on filr with the NPI registry.
