Claim Status Operating Rules

The CAQH CORE Claim Status Operating Rules enhance the exchange of claim status information between health plans and provider through consistent infrastructure including requirements that allow providers to check the status of a claim electronically, without manual intervention, or confirm claims receipt.

Regulatory Status

In December 2011, CMS issued a notice adopting CMS-0032-IFC: Administrative Simplification: Adoption of Operating Rules for Eligibility for a Health Plan and Health Care Claim Status Transactions as a Final Rule. All HIPAA-covered entities are required by Federal law to adopt the CAQH CORE Eligibility & Benefits Operating Rules and the CAQH CORE Claim Status Operating Rules*, by January 1, 2013.

*NOTE: In the Final Rule for Administrative Simplification: Adoption of Operating Rules for Eligibility for a Health Plan and Health Care Claim Status Transaction, CAQH CORE requirements pertaining to use of Acknowledgements are NOT included for adoption. Although HHS is not requiring compliance with any operating rule requirements related to Acknowledgements, the Final Rule does note -- “we are addressing the important role acknowledgements play in EDI by strongly encouraging the industry to implement the acknowledgement requirements in the CAQH CORE rules we are adopting herein.”
