During the initial setup of EDI/ERAs, the insurance company will often share information regarding enrolling for EFT payments, instead of receiving paper checks.
The setup is separate from EDI (claim submission ) and ERA (electronic EOBs) because EFT (electronic funds transfer) involves your banking information.
You can also look on each payer's website, as they will have instructions on how to convert paper checks, and/or electronic payment cards to EFT so payment will deposit directly into your bank account.
You will be able to identify those payments that are directly deposited into your account by looking under Billing > Remittance Reports. Direct Deposits will be listed as "Automated Clearing House (ACH)". The word "check" will identify payments that were made by paper checks.
