Additional EDI Formats
(Rev. 2803, Issued: 10-28-13, Effective: 09-17-13, Implementation: 09-17-13)
Providers who receive or send transactions directly from/to more than one A/B MAC
and/or CEDI, and billing services and clearinghouses that receive or send transactions
from/to more than one A/B MAC and/or CEDI, must contact each A/B MAC and/or
CEDI with which they receive/send EDI transactions to inquire about the need for
supplemental testing whenever they plan to begin to use an additional type of EDI
transaction. A provider must also notify their A/B MAC and/or CEDI in writing (see
EDI enrollment in Section 30 of this chapter) if they will begin to use a billing agent or
clearinghouse for the first time, change a billing agent or clearinghouse, discontinue use
of any billing agent or clearinghouse, or authorize a billing agent or clearinghouse
currently used for some transactions to begin receiving additional transactions. A billing
agent or clearinghouse representative is prohibited from signing an authorization on
behalf of a provider to allow them to act as the sender or receiver of specific EDI
transactions on behalf of a provider, even if a provider has signed a contract with the
billing agent or clearinghouse for such services.
