[HAPI-devel] Request for Utility Methods or Documentation for CodeableConcept /Extension Retrieval

[Shreeja J <mai...@gm...>]

Hello Team,
I am currently working with the HAPI HL7v2 and HAPI FHIR libraries, and I
am seeking guidance on utility methods or documentation that would help me
retrieve the system, code, and display values for HL7 terminologies.

  For example, if I pass a code like "MR", I would expect the method to
return:

{

  "type": {
    "coding": [{
      "system": "http://terminology.hl7.org/CodeSystem/v2-0203",
      "code": "MR"
    }]
  }
}

Similarly, if the code "2028-9" is passed, the expected output would be:
{
  "system": "urn:oid:2.16.840.1.113883.6.238",
  "code": "2028-9",
  "display": "Asian"
}

For the code "confirmed", the output should be:
{
  "coding": [{
    "system": "http://terminology.hl7.org/CodeSystem/condition-ver-status",
    "code": "confirmed",
    "display": "Confirmed"
  }]
}
 If there are any generic utility methods available that I can leverage to
retrieve these details, or if there is any relevant documentation you could
guide me to, I would greatly appreciate your assistance.

Thanks,
Shreeja
