Features of EDI 837P- Part III

BHT Segment:

BHT*0019*00*565743*20110523*154959*CH~

This segment conveys the electronic transmission status of the 837 batch contained in this ST-SE envelope(BHT02). Here 00 for original and 18 for reissue. This segment also contains Reference identification for tracking purpose(BHT03), Current Date(BHT04), Current Time(BHT05) and Transaction type(BHT06)- CH for service claims and RP for reporting encounters.

NM1 Segment:

NM1*41*2*SAMPLE INC*****46*496103~

NM1 refers to an organization, a physical location, property or an individual. So to determine whether NM1 Segment is the submitter Segment(41) or the receiver Segment(40) or the billing provider Segment(85) or the referring provider Segment(DN) or the rendering provider Segment(82)  or some other Segment, we have to check the value of NM101.

Most of the time NM1 Segment is the beginning of a loop. So it may be followed by other segments like PER Segment (EDI Contact Name), N3 Segment (Street address), N4 Segment (City, State and zip code), etc.

Segment		NM101 Meaning		Name of the Loop
NM1*41*2	Submitter Identifier Code		1000A loop
NM1*40*1	Receiver Identifier Code		1000B loop
