ERA / 835 (Electronic Remittance Advice)
The electronic file a payer sends that details how a claim was adjudicated - payments, adjustments and denial codes.
The ERA (in the 835 format) lets payments post automatically with line-level reconciliation, far faster than manual EOB entry. It carries the CARC/RARC codes that drive denial work.
Automated 835 posting is a big time-saver in the back office.
