0. Extension
Definition | This FHIR Extension for multiple prescriptions adds details such as repetition count and time intervals for repeated medication orders to FHIR resources. Optional Extension Element - found in all resources.
Short | MultiplePrescriptionOptional Extensions Element
Control | 0..* This element is affected by the following invariants: ele-1
Is Modifier | false
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
2. Extension.extension
Definition | An Extension 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.
Short | ExtensionAdditional content defined by implementations
Comments | 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.

Definition | A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.
Short | Description of identifier
Comments | 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.
Control | 0..01 This element is affected by the following invariants: ele-1
Binding | Unless not suitable, these codes SHALL be taken from Identifier Type Codes http://hl7.org/fhir/ValueSet/identifier-type|4.0.1 (extensible to `http://hl7.org/fhir/ValueSet/identifier-type|4.0.1` ) A coded type for an identifier that can be used to determine which identifier to use for a specific purpose.

Primitive Value | This primitive element may be present, or absent, or replaced by an extension

Fixed Value | `urn:ietf:rfc:3986`
Example | General: http://www.acme.com/identifiers/patient
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))

Comments | If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
96. Extension.extension:id.value[x].type
Definition | A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.
Short | Description of identifier
Comments | 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.
Control | 0..0 This element is affected by the following invariants: ele-1
Binding | Unless not suitable, these codes SHALL be taken from Identifier Type Codes (extensible to `http://hl7.org/fhir/ValueSet/identifier-type|4.0.1` ) A coded type for an identifier that can be used to determine which identifier to use for a specific purpose.

Type | uri
Is Modifier | false
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
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.
Fixed Value | `urn:ietf:rfc:3986`
Example | General: http://www.acme.com/identifiers/patient
Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
100. Extension.extension:id.value[x].value
Definition | A unique ID that is identical across all partial prescriptions of a multiple prescription.
Short | Multiple Prescription ID
Comments | If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

102. Extension.extension:id.value[x].period
Definition | Time period during which identifier is/was valid for use.
Short | Time period when id is/was valid for use
Comments | A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times"). Period is not used for a duration (a measure of elapsed time). See Duration.
