On February 1, 2014, CORE released an updated version of the CORE Code Combinations for use with the CAQH CORE 360: Uniform Use of CARCs and RARCs Rule. The CORE Code Combinations align with the current published CARC and RARC lists, which are updated at least three times per year.
According to CORE, “CAQH CORE Rule 360 enables more uniform use of the Claim Adjustment Reason Codes (CARCs) and Remittance Advice Remark Codes (RARCs) by targeting a minimum set of common or problematic Business Scenarios along with a maximum specified set of code combinations for each of these Scenarios.”
Implementation of the CAQH CORE 360: Uniform Use of CARCs and RARCs (835) Rule is mandated by the EFT & ERA Operating Rules of the Affordable Care Act (ACA).
