How to create BackboneElement for Carin BB

[jineesh M G]

Can anybody help me to create custom resource for Carin BB. There is one supportingInfo property in BackboneElement

Thanks,

MG

The Carin BB project has defined several profiles, which are all based on regular FHIR resource types. With the Firely .Net SDK you can use one of those from Hl7.Fhir.Model and fill it with the data you have. There is no need to create any custom structure.

For example, if you need to work with 'C4BB Coverage', this is a 'Coverage' resource, and you can do a 'var c = new Coverage();' to initialize your object and work with that.

Hi Mirjam,

Thanks for your support. I understood that. But I am particularly stuck on the some properties. For example in the case of Coverage there is "Class " and "class:group"(Slice definition and Backborn element). I could not find a way to create those properties to to Coverage object. Could you please point out to some resources?

Thanks,

MG

Hi Mirjam, 

Please ignore my previous comment. Actually, there is no issue with Coverage but I have issues with C4BB-ExplanationOfBenefit. 

There is a property "SupportInfo" and "supportingInfo:admissionperiod" I could not find a way to add that property. Those are slice definition and Backborn element

Ah, yes, that's a confusing thing when you encounter slicing for the first time. The 'admissionperiod' part of the name is just a human display name of that slice of 'supportingInfo'. Filling it in, is just filling in the supportingInfo field, while you adhere to the rules in the definition. Something like this could work:

```

            var eob = new ExplanationOfBenefit();

            var admissionperiod = new ExplanationOfBenefit.SupportingInformationComponent();

            admissionperiod.Category = new CodeableConcept("https://build.fhir.org/ig/HL7/carin-bb/CodeSystem-C4BBSupportingInfoType.html", "admissionperiod");

            admissionperiod.Timing = new Period(new FhirDateTime("2021-01-15"), new FhirDateTime("2021-01-19"));

            eob.SupportingInfo.Add(admissionperiod);

```
