Non-encodable medication

• You don’t know the RxNorm code and RxNorm is the only available code system:

<manufacturedMaterial>
   < code nullFlavor="OTH" codeSystem="2.16.840.1.113883.6.88" codeSystemName="RxNorm">
      <originalText>description of medication (anything from a fully described foreign brand to ‘little red pill’)</originalText>
   < /code>
</manufacturedMaterial>

• There is no applicable RxNorm code, but there is a code from another code system:

<manufacturedMaterial>
   < code nullFlavor="OTH" codeSystem="2.16.840.1.113883.6.88" codeSystemName="RxNorm">
      <translation code="xxxx" codeSystem="x.x.x.x.x" codeSystem="CVX or some other code system"/>
   < /code>
</manufacturedMaterial>
