Electronic Data Interchange is the plumbing between your practice and every payer: 837 files carry claims out, 835 files carry payment and adjustment detail back, 270/271 handles real-time eligibility, and 277CA acknowledgments report whether claims were accepted. When the plumbing leaks — an unenrolled payer, a misrouted ERA, a rejected 837 file with no monitoring — payments stall silently. We configure and monitor the entire layer.
EFT enrollment is payer-by-payer paperwork: banking forms, authorization signatures, and submission through each plan's own portal or clearinghouse channel. We complete and track every enrollment until direct deposits activate, then verify the first deposit actually lands in the right account with the right trace numbers.
The ERA side matters just as much. An 835 file contains the payment, the contractual adjustment, and the patient responsibility breakdown — the data that makes same-day posting and accurate patient billing possible. Auto-posting rules are configured so remittances land on the correct encounters, variances are flagged for human review rather than written off, and nothing sits in an unposted suspense queue quietly aging.
Outbound, every claim leaves as an 837 transaction through your clearinghouse — and every submission is watched through its 277CA acknowledgment, the technical receipt telling you the payer accepted the file. Rejected files are triaged the day the acknowledgment lands, because an unmonitored rejection is a claim that never existed as far as the payer is concerned.
