We have multiple NTE segments in the ADT message. I need to loop through all of the NTE segments looking for "NAVIRADTHPT" in the NTE-4 field. I have yet to get this to work using the following code.

HL7.(NTE:4()) Contains "<NAVIRADTHPT>"

Here's how the segments look.

NTE|1||This patient is currently being seen for radiation therapy.|AHRADTHPT||20210223093342
NTE|2||This patient is currently being seen for radiation therapy.|NAVIRADTHPT||20210223113634
