HHS Recommends CAQH CORE Operating Rules for federal adoption.

HHS Recommends CAQH CORE Operating Rules for federal adoption.

January 26, 2024

What comes next?


Since its formation, the Committee on Operating Rules for Information Exchange (CORE) has developed eight sets of operating rules to streamline transactions and remove cost and complexity from the healthcare ecosystem. Four of these rule sets — which address eligibility and benefits; claim status; payment and remittance; and connectivity requirements — have been federally mandated. 

Earlier this year, the National Committee on Vital and Health Statistics (NCVHS), a federal advisory body to HHS, recommended another set of CORE Operating Rules for federal adoption. Here’s what you need to know:


How do CORE Operating Rules increase collaboration in healthcare? 

Each operating rule was developed through an industry led, consensus-based process that included health plans, providers, government entities, vendors, clearinghouses, associations and others–ensuring that they provide value to the stakeholders who rely on them.

Further, by increasing standardization across the industry, the rules make it easier for entities to work together, exchange information and, ultimately, provide a better experience for patients. 


What comes next in the process for federal adoption?

If HHS supports the NCVHS recommendation, an Interim Final Rule (IFR) will be issued with public comment period. Once HHS finalizes the rule, industry stakeholders would have 25 months to implement the newly mandated operating rules.
