EDI processing
EDI claims, ERAs, and eligibility — automated end to end
One pipe to 10,000+ payers. We handle X12 837 claim submission, 835 ERA posting, 270/271 eligibility, 276/277 claim status, and 278 prior auth — with automated 999 and 277CA reconciliation.

837 claim submission
Professional, institutional, and dental claims batched, scrubbed, and acknowledged in real time.
835 ERA auto-posting
ERAs split by TIN/NPI and posted to your PM with adjustment-code mapping.
270/271 eligibility
Sub-second real-time eligibility with caching for batch verification at the start of every day.
Rejection workflow
277CA and payer-specific rejections routed to a worklist with remediation hints.
Enrollment tracking
We file, track, and resubmit payer enrollments — including ERA and EFT.
HL7 + FHIR ready
Adapt EDI to FHIR R4 Claim, ClaimResponse, and Coverage resources when needed.
How EDI flows through Synergy
- Your PM/EHR drops an 837 to SFTP or POSTs to our REST endpoint.
- We scrub for payer-specific edits, generate a 999, and route to the clearinghouse.
- 277CA and 835 responses are parsed, posted, and surfaced in your rejection worklist.
- Eligibility (270/271) and claim status (276/277) run on demand or on a schedule.
