Please see pages on the 276-277 and the 270-271 in the Medicare Electronic Billing and Electronic Data Interchange (EDI) Transactions section of this Web site for further information on use of those transactions. There are also pages in that section on Medicare electronic claims, remittance advice, and coordination of benefit transactions for which statistics are included in this section of the Centers for Medicare and Medicaid Services (CMS) Web site.
