The Health Insurance Portability and Accountability Act (HIPAA) mandates the standardization of EDI formats for health care data transmission, which includes claims, remittance, eligibility, and claim status inquiries. HIPAA regulations replace the CMS 1500 and UB04 Claims formats with ASC X12N 837 Transactions.
The Blue Cross and Blue Shield of North Carolina (Blue Cross NC) Companion Guides are available to assist trading partners in understanding Blue Cross NC code and situation handling used in processing the ANSI ASC X12N Transactions. The X12 version 5010 of the Companion Guide is available.
