Section title: Requests for Interpretation
Repeated Use of Segments with same Qualifier

Question: The base X12 EDI standard does not specifically address whether repeated use of loops/segments with the same qualifier is permitted or not. Some industries, for example, rail transportation, have a need to use loops/segments with the same qualifier multiple times in the same transaction. Is this approach permitted or not in the X12 standard?

Scenario: In some industries some implementors are instructed to repeat the use of the loop/segment with the same qualifier/code. This is causing confusion for implementers of the healthcare TR3s which are unsure whether or not this is permitted.

RFI Response

Yes, the approach is permitted within the X12 standard. For additional information consult previous RFI's: 1838, 2069, and 2472, and this X12 Blog.
