CAQH® Committee on Operating Rules for Information Exchange (CORE®)
CAQH® CORE® is an industry-wide stakeholder collaboration committed to the development and adoption of national operating rules for administrative transactions.
The Department of Health and Human Services (HHS) designated CAQH® CORE® as the author of national operating rules for the HIPAA-covered administrative transactions.
The U.S. Department of Health and Human Services issued regulations which adopted the CAQH® CORE® Operating Rules, with the exception of acknowledgment provisions, for the following transactions:
- Eligibility & Benefits -- X12/005010X279A1 Eligibility Benefit Inquiry and Response (270/271).
- Claim Status – X12/005010X212 Health Care Claim Status Request and Response (276/277).
- Payment & Remittance – X12/005010X221A1 Health Care Claim Payment Advice (835) and EFT (ACH Electronic Funds Transfer).
See the Federally Mandated page for additional details
CAQH® CORE® also offers voluntary certification for each set of operating rules approved by its Board and Membership.
In 2020, CAQH® CORE® restructured its operating rules from a phased-based approach to a transaction-based approach.
The original structure of phase-based rules was:
- Phase I: Eligibility and Benefits
- Phase II: Eligibility and Benefits enhancements and Claim Status
- Phase III: EFT/ERA
- Phase IV: Claims and Encounters, Benefit Enrollment, Premium Payment, Prior Authorization
- Phase V: Prior Authorization enhancements
The new structure organizes rules by administrative transaction (such as Eligibility & Benefits) or rule focus (such as Patient Attribution). For more information, click the plus sign on the right navigation frame of this page and select the topic you wish to view.
