CAQH CORE has updated its operating rule structure. The CAQH CORE FAQs are in the process of being updated to align with the new structure. CAQH CORE appreciates your patience as these updates are made.
Implementation of the CAQH CORE Operating Rules for Eligibility & Benefits, Claim Status and Payment & Remittance is mandated for all HIPAA-covered entities by the ACA (with the exception of requirements pertaining to acknowledgments). Implementation of the CAQH CORE Operating Rules for Prior Authorization & Referrals, Health Care Claims, Benefit Enrollment and Premium Payment is currently voluntary. HHS will determine whether the voluntary CAQH CORE Operating Rules will be included in any future regulatory mandates. CAQH CORE offers CORE Certification for all the CAQH CORE Operating Rules
