Electronic Funds Transfer

Electronic Funds Transfer Form and Instructions

To initiate the EFT process, you will need to complete the Electronic Funds Transfer (EFT) Authorization Agreement (CMS-588). By signing the CMS-588 form, you are certifying the account is in compliance with the CMS instructions. The agreement must be signed by the authorized or delegated official who signed the Medicare enrollment application. If the appropriate CMS-855 Medicare Enrollment Application form is not on file in our office, the provider must submit one before the EFT can be established.

Submitting the EFT Form

Return completed EFT forms to the appropriate office location so that processing can be finalized.
