Message type field
This path specifies the Message
Type field (ID 00013) in the MSH
segment:
0(0).MSH(0).00013
Dots (.
) separate path items. Individual items are:
-
0(0)
The first instance of the first segment group.
-
MSH(0)
The first instance of the MSH segment in the group.
-
00013
Field number 00013. This number does not have a repetition count. If the last item in an HL7 object path does not have an explicit instance count specified, then
(0)
is assumed.
For example, in the ADT_A17
message definition:
MSH
EVN
{
PID
PV1
}
The first two segments, MSH
and EVN
, are required and
display exactly once.
The next pair of segments, PID
and PV1
, must display at
least once, but more instances of the pair are permitted.
The PID
-PV1
pair is the second group in the
message.
MSH 0(0).MSH
EVN 0(0).EVN
{
PID 1(0).PID
PV1 1(0).PV1
}
Two or more segments can be present in a repeating group, marked by curly braces, or in an optional group, marked by square brackets. In these cases, they must have a separate group number.
All the items within a pair of curly braces or square brackets are in the same group number.
The PID
-PV1
pair is the second group in the message:
1(0)
.
