0. Extension
Definition	This extension is used to provide the GFE Service Linking Information. This allows implementers to have the same identifier on multiple GFEs that are part of one period of care's services. This would be needed for some of the workflow options that businesses may decide to use. Optional Extension Element - found in all resources.
Short	ExtensionOptional 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()`) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
2. Extension.extension:plannedPeriodOfService
Slice Name	plannedPeriodOfService
Definition	A timeframe (scheduled or requested) during which a patient is expected to receive healthcare services generally related to a specific treatment goal, episode of care, or clinical objective as outlined in a Good Faith Estimate (GFE). This period typically begins with the initial scheduled service and includes all reasonably expected items and services that are associated with that primary service, even if rendered by different providers or facilities.

4. Extension.extension:plannedPeriodOfService.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.

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.

Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
20. Extension.extension:linkingIdentifier.value[x].system

Short	The namespace for the identifier value
Comments	Identifier.system is always case sensitive.
Control	10..1
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.
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()))
22. Extension.extension:linkingIdentifier.value[x].value
Definition	The portion of the identifier typically relevant to the user and which is unique within the context of the system.
Short	The value that is unique
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.
Control	10..1
Type	string

Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
24. Extension.extension:anticipatedSubmittingProviderCount
Slice Name	anticipatedSubmittingProviderCount
Definition	The total number of providers that are expected to submit a GFE as part of a planned period of service or estimate request. This number includes all co-provider and the convening provider (if the convening provider is submitting a GFE). If this value is provided in more than one resource and there is a conflict in the number, the extension as part of the GFE Composition as part of the GFE Packet will be the definitive number.
Short	Total number of providers that are expected to submit GFEs.Additional content defined by implementations
Comments	The count of GFE submitting providers is useful for an intermediary or a payer that is collating multiple GFE submissions from multiple providers. This element is highly recommended if there are GFEs that will be submitted from multiple providers and is not needed if there is only a single submitting provider (e.g. only a single provider GFE or is the GFE Coordination process was done before submitting the GFE Packet).

Type	code
Is Modifier	true because This is labeled as "Is Modifier" because applications should not mistake a temporary id for a permanent one.
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
Summary	true
Requirements	Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.
Invariants	ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
32. Extension.extension:linkingIdentifier.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..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.

Requirements	Allows users to make use of identifiers when the identifier system is not known.
Invariants	ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
34. Extension.extension:linkingIdentifier.value[x].system
Definition	Establishes the namespace for the value - that is, a URL that describes a set values that are unique.
Short	The namespace for the identifier value
Comments	Identifier.system is always case sensitive.
Control	1..1
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.
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())`)
36. Extension.extension:linkingIdentifier.value[x].value
Definition	The portion of the identifier typically relevant to the user and which is unique within the context of the system.
Short	The value that is unique
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.

40. Extension.extension:linkingIdentifier.value[x].assigner
Definition	Organization that issued/manages the identifier.
Short	Organization that issued id (may be just text)
Comments	The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization.
Control	0..1

42. Extension.extension:anticipatedSubmittingProviderCount
Slice Name	anticipatedSubmittingProviderCount
Definition	The total number of providers that are expected to submit a GFE as part of a planned period of service or estimate request. This number includes all co-provider and the convening provider (if the convening provider is submitting a GFE). If this value is provided in more than one resource and there is a conflict in the number, the extension as part of the GFE Composition as part of the GFE Packet will be the definitive number.
Short	Total number of providers that are expected to submit GFEs.
Comments	The count of GFE submitting providers is useful for an intermediary or a payer that is collating multiple GFE submissions from multiple providers. This element is highly recommended if there are GFEs that will be submitted from multiple providers and is not needed if there is only a single submitting provider (e.g. only a single provider GFE or is the GFE Coordination process was done before submitting the GFE Packet).
