# description
This identifier profile defines a Pensioner Concession Card number in an Australian context (see [Services Australia](https://www.servicesaustralia.gov.au/individuals/services/centrelink/pensioner-concession-card) or [Department of Veterans' Affairs](https://www.dva.gov.au/health-and-treatment/veteran-healthcare-cards/pensioner-concession-card)).

This definition supports sending the Centrelink Customer Reference Number (CRN) (also referred to as unique identifier number (UIN) in the Centrelink Confirmation eServices (CCeS)) as displayed on the individual's Pensioner Concession Card (see [Services Australia](https://www.servicesaustralia.gov.au/individuals/subjects/centrelink-customer-reference-number-crn) for further information). An individual's CRN is present as the primary identifier on different concession cards and is used to confirm concessions by most government agencies and utility providers.

A Pensioner Concession Card may be issued by Services Australia or Department of Veterans' Affairs (DVA) to pensioners and selected benefit recipients to assist them with certain living costs, by allowing access to specific goods and services at a concessional rate.

# snapshot.element[].definition
Pensioner Concession Card number as the Centrelink Customer Reference Number (CRN) (also referred to as unique identifier number (UIN) in the Centrelink Confirmation eServices (CCeS)) displayed on the individual's Pensioner Concession Card.

# snapshot.element[].constraint[].human
All FHIR elements must have a @value or children

# snapshot.element[].constraint[].expression
hasValue() or (children().count() > id.count())

# snapshot.element[].mapping[].map
CX / EI (occasionally, more often EI maps to a resource id or a URL)

# snapshot.element[].mapping[].map
II - The Identifier class is a little looser than the v3 type II because it allows URIs as well as registered OIDs or GUIDs.  Also maps to Role[classCode=IDENT]

# snapshot.element[].definition
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

# snapshot.element[].slicing.description
Extensions are always sliced by (at least) url

# snapshot.element[].short
Additional content defined by implementations

# snapshot.element[].definition
May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance  applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

# snapshot.element[].comment
There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions.  The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

# snapshot.element[].constraint[].human
All FHIR elements must have a @value or children

# snapshot.element[].constraint[].expression
hasValue() or (children().count() > id.count())

# snapshot.element[].constraint[].human
Must have either extensions or value[x], not both

# snapshot.element[].short
usual | official | temp | secondary | old (If known)

# snapshot.element[].comment
Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.

# snapshot.element[].requirements
Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.

# snapshot.element[].constraint[].human
All FHIR elements must have a @value or children

# snapshot.element[].constraint[].expression
hasValue() or (children().count() > id.count())

# snapshot.element[].isModifierReason
This is labeled as "Is Modifier" because applications should not mistake a temporary id for a permanent one.

# snapshot.element[].binding.description
Identifies the purpose for this identifier, if known .

# snapshot.element[].definition
A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.

# snapshot.element[].comment
This element deals only with general categories of identifiers.  It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage.   Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.

# snapshot.element[].requirements
Allows users to make use of identifiers when the identifier system is not known.

# snapshot.element[].constraint[].human
All FHIR elements must have a @value or children

# snapshot.element[].constraint[].expression
hasValue() or (children().count() > id.count())

# snapshot.element[].binding.description
A coded type for an identifier that can be used to determine which identifier to use for a specific purpose.

# snapshot.element[].definition
Establishes the namespace for the value - that is, a URL that describes a set values that are unique.

# snapshot.element[].comment
Identifier.system is always case sensitive.

# snapshot.element[].requirements
There are many sets  of identifiers.  To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.

# snapshot.element[].short
Centrelink CRN as displayed on the Pensioner Concession Card

# snapshot.element[].definition
The portion of the identifier typically relevant to the user and which is unique within the context of the system.

# snapshot.element[].comment
A Centrelink CRN is a 10 character identifier in the format of 9 digits ending with a letter. This concept is equivalent to Australian Institute of Health and Welfare data element 690579 [Person—government funding identifier, Centrelink customer reference number N(9)A](https://meteor.aihw.gov.au/content/index.phtml/itemId/690579).
