What Is Clearinghouse?
A clearinghouse is a HIPAA-defined entity that processes health information from one format into a standard electronic format and transmits 837 claims, 835 remittances, 270/271 eligibility, and 276/277 claim status transactions between providers and payers.
- The 2024 Change Healthcare ransomware outage exposed concentration risk — practices reliant on a single clearinghouse experienced weeks of revenue disruption.
- Best practice is to maintain redundant clearinghouse connections (at minimum a primary plus a backup payer-direct submission path for top payers).
Clearinghouse
Also known as: EDI Clearinghouse; Claims Clearinghouse
A clearinghouse is a HIPAA-defined entity that processes health information from one format into a standard electronic format and transmits 837 claims, 835 remittances, 270/271 eligibility, and 276/277 claim status transactions between providers and payers.
Definition
Defined at 45 CFR 160.103, a health care clearinghouse processes nonstandard health information into standard data elements (and vice versa). Major clearinghouses include Availity, Optum (Change Healthcare), Waystar, Trizetto Provider Solutions, Office Ally, and Inovalon (formerly Capario). Clearinghouses route 837 professional and institutional claims to thousands of payer endpoints, return 999 functional acknowledgments and 277CA claim status reports, deliver 835 ERAs, and support real-time 270/271 eligibility and 276/277 claim status transactions. Clearinghouses are HIPAA covered entities and require BAAs with each provider client.
Example
A practice submits an 837P claim batch to Availity. Availity validates HIPAA syntax, rejects malformed claims (returned via 277CA), routes valid claims to the appropriate payer via direct connections or partner networks, then returns 835 ERAs back to the practice when the payer adjudicates. A typical claim's journey: provider PM → clearinghouse → payer adjudication → ERA → clearinghouse → provider PM auto-post.
Common Misconceptions
Clearinghouses are not payers — they are intermediaries. Clearinghouse rejections (999, 277CA) are different from payer denials (835 CARC/RARC); rejections never reach the payer's adjudication system, so they are not 'denials' in the contractual sense and have no statutory appeal rights.
Practical Application
The 2024 Change Healthcare ransomware outage exposed concentration risk — practices reliant on a single clearinghouse experienced weeks of revenue disruption. Best practice is to maintain redundant clearinghouse connections (at minimum a primary plus a backup payer-direct submission path for top payers).
