CMS 588 EFT Form Instructions

Electronic Funds Transfer (EFT) deposits your Medicare payments directly into your bank account. CMS requires all providers that are enrolling in Medicare Part A, revalidating, or when the EIN, pay-to address or LBN to their file is being changed, must complete the EFT. Complete the form and have it signed and dated by the provider or authorized/delegated official (for groups or organizations). The signature must be original with a date (cannot be a copy or stamped signature). To sign up, complete an Electronic Funds Transfer Authorization Agreement - CMS 588.

A group does not need to submit an EFT form for each of its members. Return the form to the address listed for your state, found on the Provider Enrollment Contacts page.
