      Include a new standard extension on patient:

      [http://hl7.org/fhir/StructureDefinition/patient-unknown-identity]

      as a CodeableConcept 0..1 bound to a new valueset (extensible).

      Definition: This extension indicates whether or not the patient's/person's identity is known.

      known       Known Identity      The patient's/person's identity is known.

      unknown   Unknown Identity  The patient's/person's identity is unknown.

       

      Some implementation(s) may leverage this extension with additional code values for other purposes such as verification level (so should not use the presence of this extension only to determine if the identity is unknown)

    Description

      As part of the v2-to-FHIR project we are mapping commonly used fields in key v2 messages to FHIR resources so that messages can be transformed into bundle of FHIR resources. PID-31 is the Identity Unknown Indicator field but there is no cognate existing data element in FHIR. We suggest that a standard extension to Patient be created to allow exchange of this concept. 

       

      We suggest a CodeableConcept value using value set http://terminology.hl7.org/CodeSystem/v2-0136 with a binding of Required (could also be a code data type if we are going with a Required binding strength).

       

      The v2 description can be reused as part of the extension narrative:

      This extension indicates whether or not the patient's/person's identity is known.  

      Y            the patient's/person's identity is unknown

      N            the patient's/person's identity is known
