The information in the service detail loops is not required. A simple authorization request does not need to have service detail information in it and your trading partner should tell you in the beginning when you set up the relationship, whether they want detail information and to what extent. In the database the detail information is stored in the EDI_AuthorizerDetail table. If no detail information is present then there will be no record in this table.
The service detail in loop 2000F of the 278 transaction can transmit a variety of information segments. When you click on the "Service Detail" tab in the main tab control you will see the following screen:
The Service Detail screen
This first tab "Review Info" looks very similar to the Review tab on the patient event level; and indeed the information goes to an UM segment. But this information is not required. Put only UM information into this screen if it differs from the information given in the loop 2000E.
In addition to the UM segment we also have fields for a proposed service data or date range that will go into a DTP segment as well as certification IDs that we transmit in REF segments.
In the bottom of the screen is a grid. Here are all the service details listed. Note that unless you click on "Add Service Details" no information is added to the request transactions. Only when you see that the grid has lines, do you get this information saved and converted to the 278 transaction set.
