The ChargeItemDefinition resource provides the properties that apply to the (billing) codes necessary to calculate costs and prices. The properties may differ largely depending on type and realm, therefore this resource gives only a rough structure and requires profiling for each type of billing code system.

An absolute URI that is used to identify this charge item definition when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which an authoritative instance of this charge item definition is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the charge item definition is stored on different servers.

Allows the charge item definition to be referenced by a single globally unique identifier.

Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version.

The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in Technical and Business Versions.

In some cases, the resource can no longer be found at the stated url, but the url itself cannot change. Implementations can use the meta.source element to indicate where the current master source of the resource can be found.

A formal identifier that is used to identify this charge item definition when it is represented in other formats, or referenced in a specification, model, design or an instance.

Allows externally provided and/or usable business identifiers to be easily associated with the module.

Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this charge item definition outside of FHIR, where it is not possible to use the logical URI.

The identifier that is used to identify this version of the charge item definition when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the charge item definition author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0). For more information on versioning knowledge assets, refer to the Decision Support Service specification. Note that a version is required for non-experimental active assets.

There may be different charge item definition instances that have the same identifier but different versions. The version can be appended to the url in a reference to allow a reference to a particular business version of the charge item definition with the format [url]|[version]. The version SHOULD NOT contain a '#' - see Business Version.

A natural language name identifying the ChargeItemDefinition. This name should be usable as an identifier for the module by machine processing applications such as code generation.

Support human navigation and code generation.

The name is not expected to be globally unique. The name should be a simple alphanumeric type name to ensure that it is machine-processing friendly.

A short, descriptive, user-friendly title for the charge item definition.

This name does not need to be machine-processing friendly and may contain punctuation, white-space, etc.

The URL pointing to an externally-defined charge item definition that is adhered to in whole or in part by this definition.

A larger definition of which this particular definition is a component or step.

As new versions of a protocol or guideline are defined, allows identification of what versions are replaced by a new instance.

The current state of the ChargeItemDefinition.

Allows filtering of charge item definitions that are appropriate for use versus not.

A Boolean value to indicate that this charge item definition is authored for testing purposes (or education/evaluation/marketing) and is not intended to be used for genuine usage.

Enables experimental content to be developed following the same lifecycle that would be used for a production-level charge item definition.

Allows filtering of charge item definitions that are appropriate for use versus not.

The date (and optionally time) when the charge item definition was last significantly changed. The date must change when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the charge item definition changes.

The date is often not tracked until the resource is published, but may be present on draft content. Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the charge item definition. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

The name of the organization or individual responsible for the release and ongoing maintenance of the charge item definition.

Helps establish the "authority/credibility" of the charge item definition. May also allow for contact.

Usually an organization but may be an individual. The publisher (or steward) of the charge item definition is the organization or individual primarily responsible for the maintenance and upkeep of the charge item definition. This is not necessarily the same individual or organization that developed and initially authored the content. The publisher is the primary point of contact for questions or issues with the charge item definition. This item SHOULD be populated unless the information is available from context.

Contact details to assist a user in finding and communicating with the publisher.

May be a web site, an email address, a telephone number, etc.

A free text natural language description of the charge item definition from a consumer's perspective.

This description can be used to capture details such as comments about misuse, instructions for clinical use and interpretation, literature references, examples from the paper world, etc. It is not a rendering of the charge item definition as conveyed in the 'text' field of the resource itself. This item SHOULD be populated unless the information is available from context (e.g. the language of the charge item definition is presumed to be the predominant language in the place the charge item definition was created).

The content was developed with a focus and intent of supporting the contexts that are listed. These contexts may be general categories (gender, age, ...) or may be references to specific programs (insurance plans, studies, ...) and may be used to assist with indexing and searching for appropriate charge item definition instances.

Assist in searching for appropriate content.

When multiple useContexts are specified, there is no expectation that all or any of the contexts apply.

A legal or geographic region in which the charge item definition is intended to be used.

It may be possible for the charge item definition to be used in jurisdictions other than those for which it was originally designed or intended.

Explanation of why this charge item definition is needed and why it has been designed as it has.

This element does not describe the usage of the charge item definition. Instead, it provides traceability of ''why'' the resource is either needed or ''why'' it is defined as it is. This may be used to point to source materials or specifications that drove the structure of this charge item definition.

A copyright statement relating to the charge item definition and/or its contents. Copyright statements are generally legal restrictions on the use and publishing of the charge item definition.

Consumers must be able to determine any legal restrictions on the use of the charge item definition and/or its content.

The date on which the resource content was approved by the publisher. Approval happens once when the content is officially approved for usage.

The 'date' element may be more recent than the approval date because of minor changes or editorial corrections.

The date on which the resource content was last reviewed. Review happens periodically after approval but does not change the original approval date.

Gives a sense of how "current" the content is. Resources that have not been reviewed in a long time may have a risk of being less appropriate/relevant.

If specified, this date follows the original approval date.

The defined billing details in this resource pertain to the given billing code.

The defined billing details in this resource pertain to the given product instance(s).

In case of highly customized, individually produced or fitted devices/substances, the pricing information may be different for each instance of the product. This reference links pricing details to specific product instances.

Expressions that describe applicability criteria for the billing code.

The applicability conditions can be used to ascertain whether a billing item is allowed in a specific context. E.g. some billing codes may only be applicable in out-patient settings, only to male/female patients or only to children.

An expression that returns true or false, indicating whether the condition is satisfied. When using FHIRPath expressions, the %context environment variable must be replaced at runtime with the ChargeItem resource to which this definition is applied.

Please note that FHIRPath Expressions can only be evaluated in the scope of the current ChargeItem resource to which this definition is being applied. FHIRPath expressions can traverse into other resources linked from the ChargeItem resource, however, testing rules such as that a billing code may be billed only once per encounter need a wider scope. In such scenarios, CQL may be the appropriate choice.

The period during which the charge item definition content was or is planned to be in active use.

Allows establishing a transition before a resource comes into effect and also allows for a sunsetting process when new versions of the charge item definition are or are expected to be used instead.

The effective period for a charge item definition determines when the content is applicable for usage and is independent of publication and review dates. For example, a measure intended to be used for the year 2016 might be published in 2015.

Reference to / quotation of the external source of the group of properties.

Group of properties which are applicable under the same conditions. If no applicability rules are established for the group, then all properties always apply.

Expressions that describe applicability criteria for the priceComponent.

The applicability conditions can be used to ascertain whether a billing item is allowed in a specific context. E.g. some billing codes may only be applicable in out-patient settings, only to male/female patients or only to children.

The price for a ChargeItem may be calculated as a base price with surcharges/deductions that apply in certain conditions. A ChargeItemDefinition resource that defines the prices, factors and conditions that apply to a billing code is currently under development. The priceComponent element can be used to offer transparency to the recipient of the Invoice of how the prices have been calculated.
