Hello,
We start off all client projects by mapping the result fields to LOINC, and then search for order panels that use those LOINC codes. There is a separate location of accessory files in the downloads that contains an Excel file of all order panels and their constituents. (http://www.loinc.org, at the bottom left of screen DOWNLOADS Accessory Files)
The messaging agreement between two sites should have contingency information on what is allowed in case a standardized code does not exist. Especially when the order panel LOINC codes are still in development. CDC representatives announced at the recent ASCP Annual Meeting (September 2013 in Chicago) that a workgroup is planned to be established to study and further develop order sets If you’ll email me at pdbanning@mmm.com, I’ll get you in touch with that representative; they are inviting the public to participate.
I would sidebar that it is a bit ironic to ask for standardized/normalized LOINC order codes on a topic of “Custom Panels”. The act of normalizing orders would drive in a different direction from customization. 😉
Have a great week,
Best Regards,
Pam Banning
