Clearinghouse

A clearinghouse is the intermediary that formats, scrubs, and routes your claims to payers and delivers their remits back — the pipe your 837 claims and 835 remittances travel through.

A clearinghouse is the middleman between your billing system and the payers. When you submit a claim, the clearinghouse takes your 837 file, runs front-end edits ('scrubbing') to catch obvious errors, translates it into the format each payer expects, and routes it to the right place. On the way back, it receives the payer's 835 remittances and acknowledgments and delivers them to you. That acknowledgment trail is quietly important: the clearinghouse's acceptance report is proof of the date a claim was submitted, which is often what wins a timely-filing appeal. Clearinghouses also enroll you to receive ERAs from each payer, which is why the 835 feed is tied to a specific clearinghouse for your tax ID — switching or re-enrolling can reroute your remits. For a practice, the clearinghouse is both a quality gate (a good clean-claim rate depends partly on its edits) and a records source (rejection reports and acceptance timestamps). Rejections that die at the clearinghouse — never reaching the payer and never posting as denials — are a common blind spot, because they don't show up in the payer's remits at all.
