Rapid EDI Trading Partner Onboarding with T-Connect

HIPAA X12 EDI transmission between the many entities in the HealthCare industry is performed using files conforming to ANSI X12 specifications. These ClaimPremium Payment and Remittance Advice EDI files may originate from payers, providers, clearinghouses, or third party administrators (TPAs). One prevalent hurdle in sending or receiving these EDI transactions is the often complex onboarding process of new trading partners.

HIPAA EDI files in X12 format may typically look similar to the sample below.


The setup process for new trading partners requires that both the sender and receiver mutually agree on the content of the header fields. The header within an X12 formatted EDI file consists of the following, shown in the first three lines of the above sample.

  • Interchange Control Header Segment (ISA) – Indicates the start of at least one Functional Group (GS) and provides the various identifiers, separators, and options used to successfully parse the file interpret its contents. This is the only segment that has a fixed length.
  • Functional Group Header (GS) – Indicates the beginning of a (functional) group of Transaction Sets (ST).
  • Transaction Set Header (ST) – Indicates the start of a single transaction set, it’s type such as 837 claim or 834 enrollment and version, for example, 005010.

Focusing again on the sample claim file we can begin to extract the information needed for the successful consumption of the file. This requires picking out several values, but we can focus on a few notable values and their purpose.



  • Element Delimiter – Specified by the fourth character in the file ‘*’ separates each individual element in the file. Taking the first line as an example, ISA01 is the element after the first asterisk ’00’, ISA16 is element after the last asterisk ‘:’.
  • Component Element Separator (ISA16) – ‘:’ delimits elements that may comprise of multiple components.
  • Segment Terminator – Specified by the character immediately after ISA16 shows that the character ‘~’ is used to separate each segment. The above sample shows one segment per line

Envelope Settings

  • Acknowledgment Requested (ISA13) – Displayed by a ‘1’ or ‘0’ instructing the recipient if an acknowledgment (999) is or is not required.
  • Interchange Usage Indicator (ISA14) – Labels the interchange as consisting of test (T) or production (P) data.
  • Sender ID Qualifier (ISA05) and Receiver ID Qualifier (ISA07) – Both ‘ZZ’ in the sample designates the type of ID that it qualifies. A value of ’30’ would present a Tax ID designated by the IRS. ‘ZZ’ is used to signify that no particular authority assigned ID numbers, but they have been mutually agreed upon by the sender and receiver.
  • Sender ID (ISA06) and Receiver ID (ISA08) – The actual identifiers for the sender and receiver, qualified by the ISA05 and 07 qualifiers.

Typical Onboarding Scenarios

By this point, you may start to realize that EDI files are pretty complex. Even the quick look through the few data elements within the first lines of the file can seem overwhelming. Indeed, the process of setting up a trading partner within most systems is an arduous process. Typically integration platforms or gateways may require you to navigate through a maze of wizards and interfaces, each requiring intimate knowledge of EDI to understand. Doing this to onboard a few partners may not present much of an issue, multiplied by tens, or even hundreds, and the time investment becomes unmanageable.
