Electronic Remittance Advice (ERA)

Electronic Remittance Advice (ERA) is the digital explanation a payer sends detailing how a claim was adjudicated, including paid amounts, adjustments, and denial reasons, typically via the EDI 835. ERAs let ASCs automate payment posting and identify underpayments quickly.

What is an Electronic Remittance Advice (ERA)?

An Electronic Remittance Advice (ERA) is the digital statement a payer issues to explain how it adjudicated a claim, detailing what was paid, what was adjusted, and why anything was reduced or denied. It is the electronic equivalent of a paper remittance and is typically delivered through the EDI 835 transaction.

The ERA breaks down each claim line with standardized codes describing adjustments and denial reasons. This structure lets software interpret the payer's decision rather than requiring a person to read it line by line.

Why is the ERA important for an ASC?

Because the ERA is machine-readable, billing systems can post payments automatically and route exceptions for follow-up, sharply reducing manual posting work. Faster, cleaner posting keeps accounts current and frees staff for higher-value tasks.

The detail in an ERA also makes underpayments and denials easier to catch quickly. For an ambulatory surgery center, comparing the remitted amounts against contracted rates surfaces discrepancies that might otherwise go unnoticed and unrecovered.
