Defines the basic properties of every data value. This is an abstract type, meaning that no value can be just a data value without belonging to any concrete type. Every concrete type is a specialization of this general abstract DataValue type.

When valued in an instance, this attribute signals the imposition of a set of template-defined constraints. The value of this attribute provides a unique identifier for the templates in question

A unique identifier that guarantees the global uniqueness of the instance identifier. The root alone may be the entire instance identifier.

The plain code symbol defined by the code system. For example, "784.0" is the code symbol of the ICD-9 code "784.0" for headache.

Specifies the code system that defines the code.

A set of other concept descriptors that translate this concept descriptor into other code systems.

A set of other concept descriptors that translate this concept descriptor into other code systems.

The plain code symbol defined by the code system. For example, "784.0" is the code symbol of the ICD-9 code "784.0" for headache.

Specifies the code system that defines the code.

The common name of the coding system.

If applicable, a version descriptor defined specifically for the given code system.

A name or title for the code, under which the sending system shows the code value to its users.

The text or phrase used as the basis for the coding.

Specifies additional codes that increase the specificity of the the primary code.

If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.

When valued in an instance, this attribute signals the imposition of realm-specific constraints. The value of this attribute identifies the realm in question

When valued in an instance, this attribute signals the imposition of constraints defined in an HL7-specified message type. This might be a common type (also known as CMET in the messaging communication environment), or content included within a wrapper. The value of this attribute provides a unique identifier for the type in question.

If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.

A human readable name or mnemonic for the assigning authority. The Assigning Authority Name has no computational value. The purpose of a Assigning Authority Name is to assist an unaided human interpreter of an II value to interpret the authority. Note: no automated processing must depend on the assigning authority name to be present in any form.

Specifies if the identifier is intended for human display and data entry (displayable = true) as opposed to pure machine interoperation (displayable = false).

Identifies the type as an HL7 Registered model

A character string as a unique identifier within the scope of the identifier root.

The common name of the coding system.

If applicable, a version descriptor defined specifically for the given code system.

A name or title for the code, under which the sending system shows the code value to its users.

The valueSet extension adds an attribute for elements with a CD dataType which indicates the particular value set constraining the coded concept.

The valueSetVersion extension adds an attribute for elements with a CD dataType which indicates the version of the particular value set constraining the coded concept.

The text or phrase used as the basis for the coding.

Specifies additional codes that increase the specificity of the the primary code.

A set of other concept descriptors that translate this concept descriptor into other code systems.

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

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.

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.
