This Task profile is used to request additional documentation ("attachments") for claims or prior authorizations.

The contained practitionerrole profile communicates the provider ID as either a unique organization/location identifier (e.g., Type 2 NPI) or unique provider identifier (e.g., Type 1 NPI) or both.

The contained patient profile represents the patient data elements used to verify patient identity.

A unique claim/prior authorization identifier (referred to as the “re-association tracking control numbers”)

Indicates why task failed or was rejected.

The code element is used to indicate the type of attachment request. The code element is a required element and must be populated with one of the following values: "attachment-request-code" or "attachment-request-questionnaire".

Reference to a contained Patient resource defined by the CDex Patient Demographics Profile. It represents the member who is subject of the claim or preauthorization and demographic data elements that are used by the Provider to verify member identity.

business identifier representing the Payer ID

The term "Provider" means a person or organization that provided the health care services to a patient.

The business identifier representing the claim or prior authorization ID

due date for the attachments

A code indicating the type of data/document to be returned

This value set includes LOINC terms that can be sent by a payer as part of an HL7 attachment request for additional documentation. It has been curated by the HL7 Payer/Provider Information Exchange (PIE) Work Group. More information about using LOINC in HIPAA attachments and the source of this value set can be found at https://loinc.org/attachments. For prior authorization, X12 PWK01 Report Type Codes may also be used.

Indicates the questionnaire to be completed.

This can be handy for commonly used questionnaires with a recognizable name.

The Payer Endpoint URL for submitting attachments using the $submit-attachment operation.

Date of service or starting date of the service for the claim or prior authorization. This element SHALL be present and precise to the day if the attachment is for a claim. It is optional if the attachment is for prior authorization.

Flag to indicate whether the requested data requires a signature.

Represent the purpose of use for the requested data.

Flag to indicate whether the requested data can be submitted in multiple submissions. The default meaning when this input is omitted is multiple-submits = "false" - all the requested data should be submitted in a single transaction.

FHIR resource(s) representing the result(s) of the attachments request.

Note that all returned attachments SHOULD comply with appropriate US-Core and/or Da Vinci profiles. The "questionnaire-response" output type is for a QuestionnaireResponse resulting from the request.

Indicates the questionnaire QuestionnaireContext resulting from the request.

This Task profile is used to request additional documentation ("attachments") for claims or prior authorizations.

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.

This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.

May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

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.

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

The business identifier for this task.

A unique claim/prior authorization identifier (referred to as the “re-association tracking control numbers”)

The purpose of this identifier.

Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.

Identifies the purpose for this identifier, if known .

Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.

Establishes the namespace for the value - that is, a URL that describes a set values that are unique.

Identifier.system is always case sensitive.

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.

The portion of the identifier typically relevant to the user and which is unique within the context of the system.

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.

The current status of the task.

These states enable coordination of task status with off-the-shelf workflow solutions that support automation of tasks.

An explanation as to why this task is held, failed, was refused, etc.

This applies to the current status. Look at the history of the task to see reasons for past statuses.

Codes to identify the reason for current status. These will typically be specific to a particular workflow.

Indicates why task failed or was rejected.

A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.

Very often the text is the same as a displayName of one of the codings.

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

Indicates the "level" of actionability associated with the Task, i.e. i+R[9]Cs this a proposed task, a planned task, an actionable task, etc.

This element is immutable. Proposed tasks, planned tasks, etc. must be distinct instances.

In most cases, Tasks will have an intent of "order".

Distinguishes whether the task is a proposal, plan or full order.

The code element is used to indicate the type of attachment request. The code element is a required element and must be populated with one of the following values: "attachment-request-code" or "attachment-request-questionnaire".

The title (eg "My Tasks", "Outstanding Tasks for Patient X") should go into the code.

A reference to a code defined by a terminology system.

Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.

Allows for alternative encodings within a code system, and translations to other code systems.

The identification of the code system that defines the meaning of the symbol in the code.

The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously.

Need to be unambiguous about the source of the definition of the symbol.

A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination).

Need to refer to a particular code in the system.

Reference to a contained Patient resource defined by the CDex Patient Demographics Profile. It represents the member who is subject of the claim or preauthorization and demographic data elements that are used by the Provider to verify member identity.

Used to track tasks outstanding for a beneficiary. Do not use to track the task owner or creator (see owner and creator respectively). This can also affect access control.

A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources.

Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

The creator of the task.

Identifies who created this task. May be used by access control mechanisms (e.g., to ensure that only the creator can cancel a task).

business identifier representing the Payer ID

When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy.

When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference

Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).

Individual organization or Device currently responsible for task execution.

The term "Provider" means a person or organization that provided the health care services to a patient.

Identifies who is expected to perform this task.

A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources.

If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

A description or code indicating why this task needs to be performed.

This should only be included if there is no focus or if it differs from the reason indicated on the focus.

Indicates why the task is needed. E.g. Suspended because patient admitted to hospital.

A reference to a code defined by a terminology system.

Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.

A resource reference indicating why this task needs to be performed.

Tasks might be justified based on an Observation, a Condition, a past or planned procedure, etc. This should only be included if there is no focus or if it differs from the reason indicated on the focus. Use the CodeableConcept text element in Task.reasonCode if the data is free (uncoded) text.

If the Task.focus is a request resource and the task is seeking fulfillment (i.e. is asking for the request to be actioned), this element identifies any limitations on what parts of the referenced request should be actioned.

Sometimes when fulfillment is sought, you don't want full fulfillment.

Usually modifier elements provide negation or qualification. 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. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

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.

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

A code or description indicating how the input is intended to be used as part of the task execution.

If referencing a BPMN workflow or Protocol, the "system" is the URL for the workflow definition and the code is the "name" of the required input.

Codes to identify types of input parameters. These will typically be specific to a particular workflow. E.g. "Comparison source", "Applicable consent", "Concomitent Medications", etc.

Inputs are named to enable task automation to bind data and pass it from one task to the next.

The value of the input parameter as a basic type.

Outputs produced by the Task.

Resources and data produced during the execution the task. This data is generated by the business logic of task execution, and is stored separately because it varies between workflows.

The name of the Output parameter.

Codes to identify types of input parameters. These will typically be specific to a particular workflow. E.g. "Identified issues", "Preliminary results", "Filler order", "Final results", etc.

Outputs are named to enable task automation to bind data and pass it from one task to the next.
