Electronic funds transfer (EFT)

Electronic claims payment through electronic funds transfer (EFT) is a secure and fast way to receive payment, reducing administrative processes. EFT deposits are assigned a trace number that is matched to the 835 Electronic Remittance Advice (ERA) for simple payment reconciliation.

As of November 1, 2021, use to register and manage EFT account changes.

Electronic remittance advice (835)

The 835 eliminates the need for paper remittance reconciliation.

Note: If you use a clearinghouse or vendor, please work with them on ERA registration and receiving your ERAs.
