HL7 Tables for VistA

HL7 Messages including those for Meaningful Use require a lot of standardized entries that come from HL7 Tables. Those tables are often based on standards or information provided by others. For Meaningful Use, there were three HL7 messages required, one for Lab Results, one for Reporting Lab Results to Public Health Agencies and one for Immunization Reporting. There were two guides provided for the latter two that are posted on the CDC web site and each contained a number of HL7 tables and other tables and standards used in the HL7 tables are drawn from the CDC web site and other locations.

John McCormack has created a new file, file 260 in the VW or WorldVistA namespace called the VW HL7 TABLES. A build has been loaded and as improvements are made, more will be uploaded here: HL7tables/trunk/kids

The data dictionary for the current iteration of file 260 follows.

I am sure that when you review the data dictionary and all the contents you will realize that this work is substantial in size and usefulness and took a lot of work to build!

We hope that you will try it, make suggestions and hopefully even adopt John's file.

This field is different from the table version which usually refers to the version of the HL7 standard which this entry supports.

Example is HL7 table 0203 (IDENTIFIER TYPE) has a user defined code issued by CDC for Org Membership. This code has a version 20100308.

DESCRIPTION: Allows a 'package" to selectively screen the

codes that it uses/supports within a HL7 table. Useful when an application only uses a subset of a HL7 or other user defined table/code system.

DESCRIPTION: An application in conjunction with the

"APPLICATION GROUP" field can enable/disable a specific member of an HL7 table or other code system from use within the application.

Example is IMMUNIZATION may utilize the HL7 table 0163 (Body Site) and only uses a subset of this table to indicate the site a vaccine was administered. Or limit the vaccines (CVX) or manufacturer codes (MVX) that can be linked/used.
