These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning.

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. To make the use of extensions safe and managable, 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.

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 managable, 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).

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.

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

The purpose of this identifier.

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

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

Identifies the purpose for this identifier, if known .

A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.

Allows users to make use of identifiers when the identifier system is not known.

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.

A coded type for an identifier that can be used to determine which identifier to use for a specific purpose.

Time period during which identifier is/was valid for use.

Organization that issued/manages the identifier.

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.

Trace number for tracking purposes. May be defined at the jurisdiction level or between trading partners.

Allows partners to uniquely identify components for tracking.

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

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

Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).

This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.

Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.

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.

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.

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

A finer grained suite of claim type codes which may convey additional information such as Inpatient vs Outpatient and/or a specialty service.

Some jurisdictions need a finer grained claim type for routing and adjudication.

This may contain the local bill type codes, for example the US UB-04 bill type code or the CMS bill type.

A more granular claim typecode.

The period for which charges are being submitted.

A number jurisdictions required the submission of the billing period when submitting claims for example for hospital stays or long-term care.

Typically this would be today or in the past for a claim, and today or in the future for preauthorizations and predeterminations. Typically line item dates of service should fall within the billing period if one is specified.

Individual who created the claim, predetermination or preauthorization.

Some jurisdictions require the contact information for personnel completing claims.

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

The provider which is responsible for the claim, predetermination or preauthorization.

Typically this field would be 1..1 where this party is accountable for the data content within the claim but is not necessarily the facility, provider group or practitioner who provided the products and services listed within this claim resource. This field is the Billing Provider, for example, a facility, provider group, lab or practitioner.

The provider-required urgency of processing the request. Typical values include: stat, normal, deferred.

The provider may need to indicate their processing requirements so that the processor can indicate if they are unable to comply.

If a claim processor is unable to complete the processing as per the priority then they should generate an error and not process the request.

The timeliness with which processing is required: stat, normal, deferred.

A code to indicate whether and for whom funds are to be reserved for future claims.

In the case of a Pre-Determination/Pre-Authorization the provider may request that funds in the amount of the expected Benefit be reserved ('Patient' or 'Provider') to pay for the Benefits determined on the subsequent claim(s). 'None' explicitly indicates no funds reserving is requested.

This field is only used for preauthorizations.

For whom funds are to be reserved: (Patient, Provider, None).

Prescription is the document/authorization given to the claim author for them to provide products and services for which consideration (reimbursement) is sought. Could be a RX for medications, an 'order' for oxygen or wheelchair or physiotherapy treatments.

Required to authorize the dispensing of controlled substances and devices.

Original prescription which has been superseded by this prescription to support the dispensing of pharmacy services, medications or products.

Often required when a fulfiller varies what is fulfilled from that authorized on the original prescription.

For example, a physician may prescribe a medication which the pharmacy determines is contraindicated, or for which the patient has an intolerance, and therefore issues a new prescription for an alternate medication which has the same therapeutic intent. The prescription from the pharmacy becomes the 'prescription' and that from the physician becomes the 'original prescription'.

The referral information received by the claim author, it is not to be used when the author generates a referral for a patient. A copy of that referral may be provided as supporting information. Some insurers require proof of referral to pay for services or to pay specialist rates for services.

Some insurers require proof of referral to pay for services or to pay specialist rates for services.

The referral resource which lists the date, practitioner, reason and other supporting information.

Facility where the services were provided.

Insurance adjudication can be dependant on where services were delivered.

A package billing code or bundle code used to group products and services to a particular health condition (such as heart attack) which is based on a predetermined grouping code system.

Required to relate the current diagnosis to a package billing code that is then referenced on the individual claim items which are specific to the health condition covered by the package code.

For example DRG (Diagnosis Related Group) or a bundled billing code. A patient may have a diagnosis of a Myocardial Infarction and a DRG for HeartAttack would be assigned. The Claim item (and possible subsequent claims) would refer to the DRG for those line items that were for services related to the heart attack event.

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

A reference to a code defined by a terminology system.

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

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.

The amount paid by the patient, in total at the claim claim level or specifically for the item and detail level, to the provider for goods and services.

Necessary to demonstrate that copayments, co-insurance and similar patient payments have been made or accounted for.

The total value of the all the items in the claim.

Used for control total purposes.
