CAQH CORE Phase II Rules
Use of the CORE Phase II rules/policies is voluntary and open to all organizations with an interest in administrative data exchange.
The Phase II rules build on the Phase I rules, with additional rules for patient identifiers, patient accumulators, claims status and connectivity. The Phase II rules also require patient financial responsibility for an increased number of service codes.
Organizations must sign a binding pledge to adopt, implement and comply with CORE Phase II rules. A CORE-authorized testing vendor must certify that 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.
