Where claims and revenue leak

Three reasons claims stall before they're paid.

A clean claim crosses four systems and two EDI standards before it pays. Each handoff is a place revenue gets stuck or lost.

01 - Lost in EDI

An 837 leaves but no 835 ever returns

A claim posts to the clearinghouse and then goes dark. Without acknowledgment tracking, billing teams discover the gap weeks later when the remittance never lands in the ERP.

RELIABILITY
02 - Manual posting

835 remittances re-keyed by hand

Payers return 835 files that someone types into NetSuite line by line. The lag delays cash posting and every keystroke risks a mismatch finance has to chase.

LATENCY
03 - No replay

A retry double-bills the payer

When a submission retries, naive pipelines fire a second 837. The payer flags a duplicate claim, the denial bounces back, and AR ages while staff untangle it.

Do you track 837 acknowledgments and matching 835s?

Yes. Every 837 is keyed and tracked, and the returning 277 or 835 reconciles against it automatically, so an unpaid or unacknowledged claim surfaces instead of going silent.

How do you prevent duplicate claim submissions?

Every sync is idempotent, keyed on the claim ID. A retried or replayed submission updates the existing claim rather than firing a second 837, so payers never see a duplicate.

Is the full claim lifecycle auditable for compliance?

Yes. Each segment exchange is logged with timestamp, payer, and amount, and every event is replayable, so finance and auditors can trace any claim end to end.

Can we post 835 remittances straight into the ERP?

Yes. Parsed 835 line items map to NetSuite or SAP postings in the visual mapper and post in real time, so cash lands without manual re-keying.
