SIU iterate help

Sorry for yet another iterate question but I didn’t find an example in the previous posts that seem to fit my needs.   😕

My vendor is asking that when we send over an SIU message that contains multiple procedures in AIS.3 that we need to send over repeating RGS, AIS, AIL and AIP segments.   Example below.   Note to keep the post sort i will have removed the MSH, SCH, NTE, PID and PV1 segments from my examples.

Vendor example of an SIU with multiple procedure codes:

RGS|1|

AIS|1||EGD|20140107130000|

AIL|1||^ROOM 3^|||20140107130000|||60|MIN|||

AIP|1||PHYSID^DRLASTNAME^DOCTORFIRSTNAME|Doctor|

RGS|2|

AIS|2||COL|20140107130000|

AIL|2||^ROOM 3^|||20140107130000|

AIP|2||PHYSID^DRLASTNAME^DOCTORFIRSTNAME|Doctor

Vendor example if only one procedure code:

RGS|1|

AIS|1||EGD|20140107130000|

AIL|1||^ROOM 3^|||20140107130000|||60|MIN|||

AIP|1||PHYSID^DRLASTNAME^DOCTORFIRSTNAME|Doctor

Our SIU interface from our EMR generates a message like this:

RGS|1||101001360^87 AMBULATORY SURGERY

AIS|1||GI2^EGD (GI DEPT USE ONLY)^EXTSCCEAP^^~GI54^COLONOSCOPY W/EGD (GI DEPT USE ONLY)^EXTSCCEAP^^|20140107092000||||||Sch

AIG|1||R101^ENDOSCOPY SUITE 1|2^RESOURCE||||20140107092000|0|MIN|40|MIN

AIP|1||0070^HEE^VERNON^^|||20140107092000|0|MIN|40|MIN

My xlate generates the message looking like this:

    Note, that the segments aren’t in order and that the AIS segment 1 and 2 contains similar information and does not show the other procedure.

2(0).0(0).RGS(0)  :  >|1||101001360^87 AMBULATORY SURGERY< 2(0).0(0).RGS(1)  :  >|2||101001360^87 AMBULATORY SURGERY< 2(0).1(0).0(0).AIS(0)  :  >|1||GI2^EGD (GI DEPT USE ONLY)^EXTSCCEAP~GI2^EGD (GI DEPT USE ONLY)^EXTSCCEAP|^^^20140106100000||||||Sch< 2(0).1(0).0(0).AIS(1)  :  >|2||GI2^EGD (GI DEPT USE ONLY)|||||||Sch< 2(0).3(0).0(0).AIL(0)  :  >|1||R102^ENDOSCOPY SUITE 2< 2(0).3(0).0(0).AIL(1)  :  >|2||R102^ENDOSCOPY SUITE 2< 2(0).4(0).0(0).AIP(0)  :  >|1||0336^CASIMO^MATTHEW|Doctor< 2(0).4(0).0(0).AIP(1)  :  >|2||0336^CASIMO^MATTHEW|Doctor< I have attached my xlate and I was hoping that someone can assist me with how I should correctly build my iterate logic.  Please.  😕  Thank you.  Ginny
