The CAQH CORE Connectivity Safe Harbor is the connectivity method that application vendors, providers, healthcare clearinghouses, and health plans (or other information sources) can be assured will be supported by any HIPAA covered entity for the mandated operating rules and/or a CORE-certified entity. Supporting the CAQH CORE Connectivity Safe Harbor means the entity is capable and ready at the time of the request from a trading partner to exchange the transaction using the CAQH CORE Connectivity Rules.

Please Note: The CAQH CORE Connectivity Rules do not require entities to remove existing connections that do not match the rule requirements, nor do they require all HIPAA covered entities to use only the CAQH CORE Connectivity Safe Harbor for all new connections. In some circumstances, trading partners may decide to continue to use an existing, non-CAQH CORE connection. However, entities must implement the capability to use the CAQH CORE Connectivity Safe Harbor and be capable and ready to use it when requested.
