Stream: IG creation
Topic: Use of Value Sets in an IG

In my IG I make extensive use of the 11073 10101 code system. This code system is already defined in FHIR by urn.iso.std.iso:11073:10101
Do I need to encapsulate this code system in a Value Set where the only member of that value set is urn.iso.std.iso:11073:10101?
Currently I just make the 'system' value of any Coding element using this code system as 'fixed' at urn.iso.std.iso:11073:10101 and do not make any reference to a Value Set.

You need to point to the value set if you want terminology validation to work. (Also, you need to be careful with "fixed" code systems - you can do that, but you should only do it in a 'slice' of Coding, not for all Codings in a CodeableConcept. Otherwise you prohibit sending translations which is a bad thing for interoperability.)

@Lloyd McKenzie I only used 'fixed' in slices. So for terminology validation I create a name of a Value Set and place one code system entry in it.

I would expect you to say: I bind to the value set that represents all codes in the code system
