Back  RFI # 610: HL Parent/Child relationship

Formal vs. Informal Help Informal Formal

Tina Pollock

Description

Can you tell me if it is acceptable to have a SINGLE HL03=20 followed by multiple HL03=22 so long as all proceeding HL03=22 pertains to the Provider contained in the previous HL03=20 or is a one to one relationship between the Parent/Child HL segments required? I've seen EDI files with both implementations. Which one is the correct interpretation of the IG?

HL Parent/Child relationship, HL=20, HL=22

Response

This issue is explicitly addressed in guide 004010X096. The description of data element 786 in HL04 states "Code indicating if there are hierarchical child data segments subordinate to the level being described." This explicitly identifies that a parent HL can have multiple child HL segments related to it. As such, either approach is valid - one HL with HL03=20 per HL with HL03=22 or one HL with HL03=20 with multiple related HLs with HL03=22 - from a technical perspective. Repeating the same parent with one child HL each time is just a less efficient, and unnecessary, approach.
