TroubleShooting Create MedicationStatement

[Wood Glass]

I have been experiencing issues whilst trying to POST a new MedicationStatement to our client site. Referring to the documentation, The only requirements to do so are:

1. resourceType (MedicationStatement)
   
2. patient (reference)
   
3. status ("active")
4. medication (either as a contained reference or a CodeableConcept)
   
5. Only MedicationStatements about home medications or historical medications can be created
   

I have confirmed my chosen medicine is a Home Medication for my test patient. I provided medication as a CodeableConcept for aspirin using rxnorm. Instead of a 201 Created with Location header, I receive a 422 Unprocessable entity. 

X-Request-Id : ffdb5ac8be9991f0372e1e6bdfddf602

Simple Example (Patient Id replaced with place holder) :
POST /MedicationStatement
Body:

{

  "resourceType": "MedicationStatement",

  "patient": {

    "reference": "Patient/12345"

  },

  "status": "active",

 "medicationCodeableConcept": {

    "coding": [

      {

        "system": "http://www.nlm.nih.gov/research/umls/rxnorm",

         "code": "1191",

         "display": "Aspirin"

      }

    ],

    "text": "aspirin"

  }

}

This behavior is consistent for differing patients, differing Home Medications, and providing medicines as a contained reference vs a CodeableConcept. I must be missing something here?

Hi Wood,
Thank you for providing the X-Request-Id!

You are receiving that error because the terminology mappings for creating MedicationStatements aren't present in the domain. Please log an SR to us with a request for the mappings.

Thanks,
