In-Use COBA Claim File Formats The current in-use production claim file formats under the COBA program, in accordance with the transaction & code sets adopted by the Secretary of Health & Human Services through a final rule published in 45 CFR 162 during 2003 and within the Federal Register February 20, 2003, are as follows: American National Standards Institute (ANSI) Accredited Standards Committee (ASC) X12N 837 version 4010A1 institutional claim ANSI ASC X12N 837 version 4010A1 professional claim National Council for Prescription Drugs (NCPDP) Version 5.1, Batch Standard 1.1 A transcript of the June 9, 2009 and the June 23, 2009 presentation (Medicaid) of the 5010 and NCPDP COB testing call is available in the download section located near the bottom of this page The Coordination of Benefits Agreement (COBA) Program establishes a nationally standard contract between CMS and other health insurance organizations that defines the criteria for transmitting enrollee eligibility data and Medicare adjudicated claim data. The CMS has transferred the claims crossover functions from individual Medicare contractors to a national claims crossover contractor, the Coordination of Benefits Contractor (COBC). This consolidation allows for the establishment of unique identifiers (COBA IDs) to be associated with each contract and create a national repository for COBA information. How the Coordination of Benefits Agreements Works Trading partners generate eligibility files using the same format that documented on the Eligibility File Format page also included drug coverage information. For those beneficiaries listed on the eligibility file the COBC will transfer claims to trading partners in the HIPAA ANSI-X12N 837 COB (version 4010-A1) and National Council for Prescription Drug Programs (NCPDP) version 5.1 batch standard 1.1 formats.
