Electronic Data Interchange (EDI) is the computer-to-computer exchange of business documents in a standardized format. EDI eliminates the need to print and mail paper business documents. Some of the advantages of electronic filing are:
- Elimination of paper documents
- Save time and money eliminating postage
- EDI editing reduces many claim errors that delay payment
- Audit reports confirm the receipt of your electronic file submitted electronically are paid faster (14 day payment floor)
Providers are required to submit their claims electronically to Medicare. There are only a few exceptions to this rule. Regardless of organizational size, all providers can successfully submit claims electronically.
Read the Electronic Billing Packet. This packet provides you with information about submitting your claims electronically to Medicare. You may visit the Cahaba website to obtain the necessary forms required for electronic billing and/or to get your remittance electronically.
