Topic: multiple code systems for one questionnaire item

If a questionnaire item has permitted answers in the dropdown list of:
a (from http://terminology.hl7.org/CodeSystem/ab)
b (from http://terminology.hl7.org/CodeSystem/ab) and
c (from http://terminology.hl7.org/CodeSystem/cdef)
then is it better to create a custom codesystem or is it commonly acceptable to just handle this
in the system field of the answerOption.valueCoding like this:
"answerOption" : [
{
"valueCoding" : {
"system" : "http://terminology.hl7.org/CodeSystem/ab",
"code" : "a",
"display" : "display for choice a"
}
},
{
"valueCoding" : {
"system" : "http://terminology.hl7.org/CodeSystem/ab",
"code" : "b",
"display" : "display for choice b"
}
},
{
"valueCoding" : {
"system" : "http://terminology.hl7.org/CodeSystem/cdef",
"code" : "c",
"display" : "display for choice c"
}
}
],

In general, don't create a new code system if there are existing ones that serve the purpose. There's no issues with drawing codes from multiple code systems if that's what's needed to meet the use-case.
