Topic: Patient.identifier.type - Identifer Type Codes
Susan Crawford (Aug 23 2017 at 16:30):
We need some clarification around which codes are valid for identifier type code. Are we only allowed to use the codes listed at http://build.fhir.org/valueset-identifier-type.html, Section 4.3.1.44.1., or can we use any code listed under http://hl7.org/fhir/v2/0203?
For example, is ‘MB’ (Member Number) a valid code for Patient.identifier[n].type.coding[n].code? Code ‘MB’ is listed at http://hl7.org/fhir/v2/0203 but not at http://build.fhir.org/valueset-identifier-type.html.

The Identifier.type binding strength is extensible, which is defined, http://build.fhir.org/terminologies.html#extensible, as:
To be conformant, codes in this element SHALL be from the specified value set if any of the codes within the value set can apply to the concept being communicated. If the value set does not cover the concept (based on human review), an alternate system.code may be used instead
