Summary
The Supporting Physician (FL82/FL83) fields on the Institutional Claim form and the Referring Physician, Service Facility, Purchased Service Supplier and line-level Supporting Provider fields on the Professional Claim form were redesigned in the October 2005 release to add support for a variable number of Reference Identifiers per provider/entity. These changes were needed to accommodate the National Provider ID (NPI) and, in general, to more effectively handle the ANSI-837 requirement to support a variable number of identifiers per provider/entity. A new intelligent dropdown control has been added to permit entry and maintenance of these "recurring" Reference IDs. This article introduces this new "Recurring Field Set" control and describes its operation.
Details
A field "set" consists of two or more logically-related fields. For example, most ANSI/X12 reference identifiers include an identification number and a type code, or qualifier. It is often a requirement to support a variable number of occurrences of a particular field set. The claim entry form provides an intelligent combo (i.e., dropdown) control to allow entry and maintenance of such recurring field sets. Here's an example from the Institutional claim form ...

To identify a recurring field set, look for the
selector which will be positioned adjacent to the rightmost field in the set. The recurring field set and associated selector function in the following manner by default:
- As the user tabs normally away from the last field in the set, the focus will automatically return to the first field in the set and the next data occurrence will be displayed. Only when all occurrences have been displayed will the focus move to the next field on the claim entry form. This behavior permits the user to view all occurrences without using the mouse, and also provides an opportunity to enter new data if desired.
- Click the selector graphic to open the dropdown list and display all existing data occurrences. A vertical scrollbar will appear as needed to permit access to all occurrences. Select an entry from the list or press the "ESC" key (or click elsewhere on the form) to close the dropdown list. The data values corresponding to the selected entry will be displayed in the field set and are now available for editing as needed.
- To add a new occurrence to a field set, either tab through all existing occurrences until an empty field set is displayed or simply select the "[Enter New ...]" item in the dropdown list.
- Press the "F7" key while positioned on any field in the set to delete the selected occurrence. You will be prompted to confirm the deletion.
- If the focus moves away from a recurring field set while an empty occurrence is displayed, the field set will automatically display the data for the first occurrence, if any, rather than leave the screen fields blank.
The edit validation process understands the recurring nature of these special field sets, and will automatically reposition to the proper occurrence when displaying edit validation errors.
