Creation of allergy returns 409 - Conflict

[Pedro Simon]

Hi! Hope you can throw me some light on this:

Example

Cerner Correlation ID: 9a1aecb7-553c-4329-96dd-d55074e0e039

The documentations for AllergyIntollerance says:

If the consumer is sending in what is deemed to be a duplicate (codified or free text), the service will update the existing allergy or reaction rather than adding a duplicate allergy or reaction.

But, if the patient has the following allergy

{

"id" => "12766873",

"meta" => { "versionId" => "12766873", "lastUpdated" => "2020-10-08T23:57:25Z" },

"clinicalStatus" => { "coding" => [{ "system" => "http://terminology.hl7.org/CodeSystem/allergyintolerance-clinical", "code" => "active", "display" => "Active" }], "text" => "Active" },

"verificationStatus" => { "coding" => [{ "system" => "http://terminology.hl7.org/CodeSystem/allergyintolerance-verification", "code" => "confirmed", "display" => "Confirmed" }], "text" => "Active" },

"type" => "allergy",

"category" => ["food"],

"criticality" => "low",

"code" => { "text" => "shellfish" },

"patient" => { "reference" => "Patient/12744859", "display" => "REVSPRING, TWO" },

"encounter" => { "reference" => "Encounter/97955344" },

"recordedDate" => "2020-10-06T20:15:05Z",

"recorder" => { "reference" => "Practitioner/1025924", "display" => "Cerner Test, Physician - Gastroenterology Cerner" },

"resourceType" => "AllergyIntolerance",

}

and I attempt to create (POST /AllergyIntolerance) an allergy by sending:

{

"clinicalStatus" => {

"coding" => [

{ "system" =>

"http://terminology.hl7.org/CodeSystem/allergyintolerance-clinical",

"code" => "active" },

],

},

"code" => {

"coding" => [

{

"system" => "http://snomed.info/sct",

"code" => "735029006",

},

],

"text" => "Shellfish",

},

"patient" => { "reference" => "Patient/12744859" },

"resourceType" => "AllergyIntolerance",

}

it returns a "409 - Conflict" response.

Is it the responsibility of the consumer (me in this case) to do code and text based comparisons to prevent sending what seems to be duplicated allergies (even if they don't match in code)? How should I handle this issue?

Thanks!
