835 ERA

Short answer

An 835, or electronic remittance advice (ERA), is the HIPAA-standard file a payer sends to report claim payments. It lists each claim and service line with the billed amount, allowed amount, paid amount, patient responsibility, and adjustment reason codes. Billing systems import 835 files to post payments automatically instead of keying them by hand.

What is inside an 835 file?

An 835 starts with payment header information, including the amount, payment method, and EFT trace or check number. It then lists claim-level and service-line-level detail. Each adjustment carries a group code and a CARC, often with RARCs that add context.

Why does the 835 matter for payment posting?

Because the 835 is structured, a practice management system can match each payment to the right claim and line, apply adjustments, and move patient balances. Posting from paper EOBs or PDFs requires a person to read and enter the same information.
