An electronic remittance advice (ERA) is the file a health plan sends to explain how it processed each of your claims.<\/p>\n <\/div>\n

The ERA explains the payment to you. The explanation of benefits (EOB) goes to the patient, and the electronic funds transfer (EFT) is the money.<\/p>\n <\/div>\n

Every ERA carries the paid amount per service line, the adjustments with their reason codes (CARCs), and the amount left with the patient.<\/p>\n <\/div>\n

ERAs are not automatic. You enroll for them payer by payer, and every plan runs its own process.<\/p>\n <\/div>\n

Posting software reads the 835 and settles claims for you, so the day’s remittances become a worklist of exceptions.<\/p>\n <\/div>\n <\/div>\n <\/div>\n \n\n\n

An electronic remittance advice (ERA) is the electronic file a health plan sends to explain how it processed your claims. Its standard format is the HIPAA 835, which is why ERA and 835 file get used interchangeably. CMS<\/a> defines it as an explanation from a health plan to a provider about a claim payment.<\/p>\n\n\n\n

After a claim goes out, one question decides everything downstream. What did the payer do with it? Your claim left the practice as an 837 file<\/a>, and the ERA is the reply.<\/p>\n\n\n\n

That reply breaks down per claim and per service line, in standard codes every plan has to use. Plenty of practices still get the same answer by logging into payer portals one plan at a time.<\/p>\n\n\n\n

This guide covers what an ERA contains, how it differs from an EOB and an EFT, and how to read one line by line. It also covers the enrollment step that has to happen before any of it turns up.<\/p>\n\n\n\n

ERA, EOB, and EFT: What’s the difference?<\/h2>\n\n\n\n

The ERA is the explanation sent to the provider. The explanation of benefits (EOB) is the version the patient gets, and the electronic funds transfer (EFT) is the money. All three describe the same claim. They arrive separately, in different places, and often on different days.<\/p>\n\n\n\n

The terminology has one wrinkle worth knowing. In the standards themselves, the provider’s remittance is sometimes called an explanation of benefits, so the two terms overlap. In everyday US billing, EOB means the patient’s copy and ERA means yours.<\/p>\n\n\n\n

The reconciliation problem is that the file and the deposit travel apart. CMS calls pairing them re-association. Both carry the same trace number, in the 835’s TRN segment and in the addenda record attached to the ACH payment. Match on that number rather than on the amount, because one deposit often covers many claims.<\/p>\n\n\n\n

This is where practices lose hours. A deposit that doesn’t equal the sum of the claims sends somebody hunting through the file for the difference. Usually it’s a provider-level adjustment, and the annotated example below has one in it.<\/p>\n\n\n\n

What’s inside an ERA<\/h2>\n\n\n\n

An ERA carries the payer’s full decision on a batch of claims, from the payment total down to the individual service line. Underneath the X12 jargon, it holds seven things.<\/p>\n\n\n\n
