Hi
I am trying to run CodeSystem Lookup operation . I want it to return following properties code, display, designation. But it only returns display, designation only not the code value . Am I missing something
https://stu3.ontoserver.csiro.au/fhir/CodeSystem/$lookup?code=12915011000036104&system=http://snomed.info/sct&property=code&property=display&property=designation

because code is not part of the output parameter. http://build.fhir.org/codesystem-operation-lookup.html
Also since you already know the code when calling this operation, why do you need the code as returned parameters?

Hi Yunwei
What I am trying to do is I want to retrieve multiple lookup codes using batch processing. Something like below. If it doesn't return the code I have to match it blindly which is not the best way to do.
{
"type" : "batch",
"resourceType" : "Bundle",
"entry" : [
{
"resource" : {
"resourceType": "Parameters",
"parameter": [
{
"name": "code",
"valueCode": "12915011000036104"
},
{
"name": "system",
"valueUri": "http://snomed.info/sct"
},
{
"name": "property",
"valueString": "display"
},
{
"name": "property",
"valueCode": "code"
},
{
"name": "property",
"valueString": "designation"
}
]
},
"request" : {
"method" : "POST",
"url" : "CodeSystem/$lookup"
}
},
{
"resource" : {
"resourceType": "Parameters",
"parameter": [
{
"name": "code",
"valueCode": "12915011000036106"
},
{
"name": "system",
"valueUri": "http://snomed.info/sct"
},
{
"name": "property",
"valueString": "display"
},
{
"name": "property",
"valueCode": "code"
},
{
"name": "property",
"valueString": "designation"
}
]
},
"request" : {
"method" : "POST",
"url" : "CodeSystem/$lookup"
}
}
]
}

it's a requirement of batching that each entry in the request has a matching entry in the response, in the same order
