This consolidation has enabled the implementation of unique identifiers (COBA IDENTIFIER) that can be assigned to each contractual and paid activity, and has created a national repository for COBA information. COBA`s business partners are issuers of a Medicare supplemental insurance policy or a public authority responsible for the management of Title XIX of the Social Security Act. They may also be a federal authority or contractor that manages and provides health care to its eligible beneficiaries, or an organization that works under a contract with a self-employed employer plan or an insurer to adjudicate rights and perform other insurance functions, including those necessary for the coordination of delivery activities. A COBA business partner does not include companies that only capture, transfer and/or translate files, for example. B clearing houses in the health sector, network service providers, data transmission services and settlement services. . . .
