Hi all,
I have a question on the 837 Professional regarding the
2000A, 2000B and 2000C loops:
It isn't clear from the IG whether or not these loop nest. That
is, in a transaction, do you have to have all the 2000A loops
(Providers) followed by all the 2000B loops (Subscribers)
followed by all the 2000C loops (Patients)?
... or ...
Can you have a Provider, followed by a Subscriber, followed by all
that Subscribers' dependants, followed by the next Subscriber,
their dependants, etc., then followed by the next provider and
so forth?
The existence of the HL segments and the way they are used seems to
indicate that the first approach is required. But in the 837 IG on
page 600-605 it seems to show the second approach.
The test data I have seen typically includes a single Provider, Subscriber
and Patient, so it could be read either way.
The tools I've seen that translate from EDI to XML have DTD's that
require the loops NOT nest.
So. Is either approach equally valid? Is it a matter for Trading
Partner agreements?
Thanks in advance,
Jim Bradford
