WRAPPER INFORMATION:

Each submitted transmission shall contain one 270 transaction with only one ISA and IEA segment, along with a transmission wrapper around the 270 transaction. The transmission wrapper Header/Trailer has no Segment ID associated with it and requires the length of the transaction message. There will be no handshake after the connection is accepted with the first submitted transmission.

Outbound response transactions will have the same format transmission wrapper. The response to the submitter will be returned in the same session in which the 270 was submitted.

Standard format of the TCP/IP Communication Transport Protocol Wrapper:

SOHLLLLLLLLLLSTXETX

SOH = Required (1 position), must be ASCII - 01

LLLLLLLLLL = Required (10 positions), Right justified with zero padded

Note: Length of the HIPAA 270 transaction not including Transmission wrapper data.

STX = Required ( 1 position), must be ASCII - 02

= Required (HIPAA 270 � ISA-IEA)
