ERA (Electronic Remittance Advice)
The electronic version of an Explanation of Benefits, transmitted from the payer to the provider in HIPAA-standard 835 transaction format. An ERA contains the same payment and adjustment information as a paper EOB but can be loaded directly into a practice management system to automate payment posting. HIPAA requires payers to transmit ERAs in the 835 format when a provider requests electronic remittance.
Why this matters for your clinic
ERAs eliminate manual payment posting, which reduces posting errors and accelerates the speed at which payments appear in your AR. A practice processing 500 claims per month manually posting paper EOBs is spending staff time that could be eliminated by ERA enrollment with each payer. Most modern practice management systems accept 835 ERAs automatically.
Beyond efficiency, ERAs are the raw data source for revenue cycle analytics. Every CARC and RARC code in the 835 file represents a reason a claim was adjusted or denied. Practices that analyze their ERA files systematically have the underlying data to track denial trends by payer, by code, and by provider. Practices that only look at the dollar amounts on the remittance summary are flying blind.
ERA enrollment is not always automatic. A practice must register for ERA delivery with each payer separately, often through a clearinghouse. Gaps in ERA enrollment mean some payers still send paper checks and paper EOBs, which fall out of the automated workflow and are more likely to be posted late or incorrectly.
What good looks like
The HIPAA-standard 835 transaction set governs ERA format. CMS publishes the 835 companion guides for Medicare. The CAQH CORE Operating Rules set baseline electronic transaction standards that most commercial payers follow. Practices should target 100% ERA enrollment with all payers accepting electronic remittance, which eliminates manual posting entirely.
Example
A physical therapy group enrolls for ERA delivery with its three largest commercial payers. The clearinghouse receives the 835 files within 24-48 hours of adjudication and loads them into the practice management system automatically. Payment posting that previously took a billing staff member two full days per week is reduced to a review-and-exception workflow taking two to three hours. The time saved is redeployed to denial follow-up, which had been the backlogged bottleneck.
From Sorso
ERA enrollment status is one of the first things we check in a new engagement. Incomplete ERA enrollment is almost always the reason some payer payments are posting late and AR for those payers looks artificially elevated.
