CAQH CORE Phase I Operating Rules
Phase I
Use of the CORE Phase I rules/policies is voluntary and open to all organizations with an interest in administrative data exchange.
Organizations must sign a binding pledge to adopt, implement and comply with CORE Phase I rules. A CORE-authorized testing vendor must certify that their systems are CORE compliant within 180 days of signing the pledge.
CORE certification is tailored for providers, health plans, vendors and clearinghouses. Organizations that do not create, send or transmit data can sign the pledge and receive a CORE Endorser seal.
