EDI 5010 Documentation–837 Professional - ISA – Interchange Control Header

 

ISA – Interchange Control Header

 

The ISA is a fixed record length segment and all positions within each of the data elements must be filled. The first element separator defines the  element separator to be used through the entire interchange. The segment terminator used after the ISA defines the segment terminator to be used throughout the entire interchange

Sample:

 

ISA*00*          *00*          *ZZ*S32433         *ZZ*Zirmed         *120921*2210*^*00501*000000246*0*P*:~

Important Note on the above sample:

 

ISA02    Since ISA is fixed length segment, even though if no values are present, we need to fill up empty spaces. Here ISA02 is filled with 10 empty spaces.

ISA04 Since ISA is fixed length segment, even though if no values are present, we need to fill up empty spaces. Here ISA04 is filled with 10 empty spaces.

ISA06 Since ISA is fixed length segment, if the value is not 15 characters length, then we need to append empty space to make 15 characters string.

ISA08

Since ISA is fixed length segment, if the value is not 15 characters length, then we need to append empty space to make 15 characters string.

 

User Name and Password
In some clearing house, they might ask to send the user name and password along with each EDI file. That's what Authorization information Information refer ISA01, ISA02,ISA03 and ISA04.  After you sign up with the clearing house, ask your user name and password to send along the EDI File if they need.  In such case, ISA01 will have the value"03" , ISA02 will have the user id, ISA03 will have the value "01" and ISA04 will have the actual password. Very important, since ISA is fixed length segment, and ISA02 is 10 character, so if your user id is less than 10 characters, then you need to append empty spaces to make it as 10 character word.
 
Sample with the User id and Password.

Code to identify the type of information in the Authorization Information

Code	Definition
00	No Authorization Information Present (No Meaningful information in 102). Advised unless security requirements Mandate use of Additional identification information.
03	Additional data Identification.

ISA03 - Security Information Qualifier

Code to identify the type of information in the Security information qualifier

Code	Definition
00	No Security Information Present (No Meaningful information in 104). Advised unless security requirements Mandate use of password data.
01	Password

ISA05, ISA07- Interchange ID Qualifier

ISA06 – Interchange Sender ID

During the sign up process with clearing house, they will assign a unique ID to the software vendor. So in the practice information setup, software should have a option to enter this value. This is mandatory for all the EDI Files, without this ID, clearing house will not be able to process the file.

ISA08 – Interchange Receiver ID

During the sign up process with clearing house, they will provide this value. Usually, this will be clearing house name. So in the practice information setup, software should have a option to enter this value. This is mandatory for all the EDI Files, without this ID, clearing house will not be able to process the file.

ISA13 – Interchange Control Number
Control Number assigned by the Sender for tracking purpose. This number must be identical to the Interchange Trailer IEA02. Ever time when creating the EDI File, software can generate a unique number to identify the batch for later case to track. 

 

ISA14 - Acknowledgement Requested.

 

Code	Definition
0	No Acknowledgement Requested
1	Interchange Acknowledgement Requested.

Default to 0. In some cases, if the software vendor integrated to clearing house via web services. then we can ask the clearing house to send the acknowledgement for each EDI File batches.

 

ISA15 – Usage Indicator.

 

Code	Definition
P	Production Data
T	Test Data

 

After the  sign up process with clearing house, they will ask the software vendor to send sample files with different use cases. In such cases, all the files should be send as Test Data. So in the practice information setup, software should have this option to select. Once test files are approved, then software admin can change this value to Production.
