Hl7 message viewer for mac12/31/2022 ![]() ![]() This is the ack sent when a message is received by the destination system. But the following are the most common HL7 message types: Hl7 Viewer Download Message Name See this document for a pretty comprehensive listing. There are more than 80 message types, a whole host of segments and codes for pretty much anything you can think of. This is the uniqueness that must be addressed by any solution in this space and the reason why HL7 implementations can sometimes be expensive - they need to take into account not only the Z segments and map them to the appropriate data models but the code sets have to be taken into account as well. An Epic code set is unique (although common across Epic deployments) and different from an AllScripts code set. So the content sent over within the HL7 message needs to be 'looked up' against that specific code set before it can be made useful. EHRs (usually) and hospitals have defined their own code sets. However, these code sets, which are released and maintained as part of the standard, aren't often adhered to. And, by the way, these code sets for HL7 have also evolved / been added to / modified with each version of HL7. ANT, as an example, stands for Anterior in the context of body sites and so on. See here for a listing of some v2.3 code sets or here for a more comprehensive listing from the 'horse's mouth.' The purpose of the code sets, as you can imagine, is to codify the content to reduce the size of the message. The HL7 organization has defined code sets to be used to translate the terse codes sent over within the HL7 message. Before you get too excited, the true customization comes in the form of the content of the HL7 message. ![]()
