**Portal:** [Medicare, Palmetto GBA (CMS-588)](https://www.palmettogba.com) · [About this portal](/reference/payers/medicare-palmetto)

## Enroll in EFT or update your bank account

These are sequential, each one depends on the last:

1. Complete Form CMS-588 (EFT Authorization Agreement) to add or change your EFT setup.
2. Attach a preprinted voided check or a bank letter showing the provider name and banking information.
3. Have the authorized representative or delegated official sign the form.
4. Submit to Palmetto GBA Part A Provider Enrollment, 2300 Springdale Drive, Building One, Camden, SC 29020 (or via PECOS).
5. Questions: Provider Contact Center 877-567-7271.

## If you are switching banks

Re-run the enrollment above with the new account details. Until the change is
confirmed, payments continue to the old account, keep it open and sweep the
balance until deposits from Palmetto GBA (Medicare MAC) appear in the new account. See
[Switch banks without missing a payer deposit](/guides/switch-banks) for the
full cutover checklist, and [EFT reassociation](/concepts/eft-reassociation)
for how to keep matching ERAs to deposits during the transition.
