Need clarity on "NullFlavor usage in CCDA files"

[csse...@metasolutionsinc.com]

Hello Team,

We are in the process of constructing CCDA files for interoperability modules for NIST stage 2 certificaion. We need clarity on using 'NullFlavor'. While generating the CCDA file, we need to build the sections even though the section does not contain any data in that for validation purpose. We got stucked when handling this issue. Currently we are using 'UNK' NullFlavor for the sections that do not have any data. Will this suffice the requirement and ATL Proctor will accept this usage of NullFlavor 'UNK' or Do we need to use any other 'NullFlavor'? Please suggest.

Any help would be greatly appreciated

Regards,

Sekhar.

Start here:

• “No information” sections (http://www.cdapro.com/know/24956)

In that article, you will also see a reference to a simpler syntax that has been approved by HL7 - but I don't know if the TTT validator supports it yet and whether it is "blessed" by ONC for MU2...

Hopefully we can learn that together on this thread and, if so, I will update the associated articles.

Note: I replaced the "image" of the sample "No Information Available" for Medications History with actual XML that you can copy/paste - and tested that it validates with errors on TTT...

Hi, Brian,

 

Did you mean to say ‘without errors’?

 

When I test with the following snippet I am passing NIST TTT and SITE C-CDA validator:

 

<section nullFlavor="NI">

  <templateId root="2.16.840.1.113883.10.20.22.2.1.1"/>

  <!-- Medication Section (entries required) -->

  <code code="10160-0" codeSystem="2.16.840.1.113883.6.1" codeSystemName="LOINC" displayName="History of Medication Use"/>

  <title>MEDICATIONS</title>

  <text>No Information</text>

</section>

 

Please post your sample if you continue to get errors.

 

Take are,

Brett

Thanks - Kyle and Brett...

I of course meant to write "without errors".

But in any case, now that the more streamlined approach is supported, that is better - and I will update my articles and samples to reflect that, in the coming days...

Hey Brett, everyone. Prior to build 179 of the TTT, the snippet listed below would not pass the validator as the tool was checking for more coded sections within the segment, and EHRs typically needed to utilize a nullFlavor to pass TTT checking of CCDA, similar to the code segment Brian showed in his link (http://www.cdapro.com/know/24956).

 

Now in build 179, the compliance checking is more relaxed and the brief mention of the template ID for sections like immunization is sufficient.

 

So Sekhar, you can incorporate something like what Brian shared on his site or utilize a more reduced code like what Brett shared.

 

I presume this is the context of clinical summary customization where summaries with clinical data removed still provide compliance CCDAs.
