On the provider side of healthcare integration, HL7 (particularly v2) is a critical message type to understand. While it is standardized and heavily used by various EHRs/EMRs, it’s used in slightly different ways.

Common HL7 messages include admissions/transfer/discharge (ADT), scheduling (SIU), lab orders and results (ORU, ORM), and medical reports (MDM). Choosing the right platform can be challenging.
Some of the challenges of HL7 2.x messages include:

Here are two of the errors that I have come across that others might have too…
One of the great things about using BizTalk Server as your integration platform is that you get a significant amount of schemas right out of the box. Microsoft has done a great job keeping up with industry standards such as EDI (supply chain logistics and more), HL7 (healthcare), HIPAA (healthcare) , SWIFT (financial services).
With BizTalk 2013, the following versions are now available:
HL7 2.5.1 and 2.6
EDI X12 5030+ and EDIFACT D05B+
Also, HL7 in BizTalk 2013 has some new features including:
Recoverable Interchange support in HL7 pipeline for Batch In Batch Out Scenario
HAT is removed, but logging feature remains intact
“Auditing and Logging Service” is renamed HL7 Logging Service”
