• FI or A/B MAC – For institutional claims, by FI that a provider chooses to process their claims. This only applies for Title XVIII FIs, as the A/B MACs will be handling institutional claims by geographic area in which the institution operates.

Medicare contractors can assist you to begin exchanging EDI transactions by furnishing you with enrollment and connectivity information, system access numbers and passwords, information on those transactions supported by Medicare Part A and Part B, and testing with you to assure correct transmission of the EDI formats. Although these contractors can supply limited EDI training, it is the responsibility of physicians, suppliers and other providers and other entities that will be using EDI to train their staff members on use of the hardware, software, and the security and privacy requirements that apply to HIPAA EDI transactions.
