CodeMapping Context should be added on the Json processor.

Current we can use that on CCDA, and Hl7v2.
There is some reason for not allow this to be used on JSON?
The code mapping context is a good approach to map the codes from the source to the correct Fhir value and it should be enable on the JSON processor

Is this being worked on as an enhancement? This will make the coding a lot easier to maintain if it is in the code mapping context.
