# US Treasury / Medicare (36 Treas 310)

> How to enroll in EFT/ERA and change your bank account for US Treasury / Medicare (36 Treas 310), step by step.

**Portal:** [Medicare, Novitas (CMS-588)](https://www.novitas-solutions.com/webcenter/portal/MedicareJH/pagebyid?contentId=00004871) · [About this portal](/reference/payers/medicare-novitas)

## 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), online through PECOS or on paper.
2. Have the provider or authorized/delegated official sign and date it with an original signature (no stamps or copies).
3. Attach a voided check or bank letterhead showing the account name, routing number, and account number.
4. Submit to Novitas Solutions Provider Enrollment, P.O. Box 3095, Mechanicsburg, PA 17055-1813 (or submit via PECOS).
5. Once verified, Medicare payments deposit directly to your account.

## 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 US Treasury / Medicare (36 Treas 310) 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.
