UsageContext

A financial tool for tracking value accrued for a particular purpose.  In the healthcare field, used to track charges for a patient, cost centers, etc.

Account

This resource allows for the definition of some activity to be performed, independent of a particular patient, practitioner, or other performance context.

Basic is used for handling concepts not yet defined in FHIR, narrative-only resources that don't map to an existing resource, and custom resources not appropriate for inclusion in the FHIR specification.

Basic

A resource that represents the data of a single raw artifact as digital content accessible in its native format.  A Binary resource can contain any content, whether text, image, pdf, zip archive, etc.

Binary

A material substance originating from a biological entity intended to be transplanted or infused into another (possibly the same) biological entity.

BodyStructure

A container for a collection of resources.

Bundle

A Capability Statement documents a set of capabilities (behaviors) of a FHIR Server for a particular version of FHIR that may be used as a statement of actual server functionality or a statement of required or desired server implementation.

CapabilityStatement

Describes the intention of how one or more practitioners intend to deliver care for a particular patient, group or community for a period of time, possibly limited to care for a specific condition or set of conditions.

CarePlan

The Care Team includes all the people and organizations who plan to participate in the coordination and delivery of care for a patient.

CareTeam

Catalog entries are wrappers that contextualize items included in a catalog.

CatalogEntry

The resource ChargeItem describes the provision of healthcare provider products for a certain patient, therefore referring not only to the product, but containing in addition details of the provision, like date, time, amounts and participating organizations and persons. Main Usage of the ChargeItem is to enable the billing process and internal cost allocation.

ChargeItem

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.

ChargeItemDefinition

A provider issued list of professional services and products which have been provided, or are to be provided, to a patient which is sent to an insurer for reimbursement.

Claim

This resource provides the adjudication details from the processing of a Claim resource.

ClaimResponse

A record of a clinical assessment performed to determine what problem(s) may affect the patient and before planning the treatments or management strategies that are best to manage a patient's condition. Assessments are often 1:1 with a clinical consultation / encounter,  but this varies greatly depending on the clinical workflow. This resource is called "ClinicalImpression" rather than "ClinicalAssessment" to avoid confusion with the recording of assessment tools such as Apgar score.

ClinicalImpression

The CodeSystem resource is used to declare the existence of and describe a code system or code system supplement and its key properties, and optionally define a part or all of its content.

CodeSystem

An occurrence of information being transmitted; e.g. an alert that was sent to a responsible provider, a public health agency that was notified about a reportable condition.

Communication

A request to convey information; e.g. the CDS system proposes that an alert be sent to a responsible provider, the CDS system proposes that the public health agency be notified about a reportable condition.

CommunicationRequest

A compartment definition that defines how resources are accessed on a server.

CompartmentDefinition

A set of healthcare-related information that is assembled together into a single logical package that provides a single coherent statement of meaning, establishes its own context and that has clinical attestation with regard to who is making the statement. A Composition defines the structure and narrative content necessary for a document. However, a Composition alone does not constitute a document. Rather, the Composition must be the first entry in a Bundle where Bundle.type=document, and any other resources referenced from Composition must be included as subsequent entries in the Bundle (for example Patient, Practitioner, Encounter, etc.).

Composition

A statement of relationships from one set of concepts to one or more other concepts - either concepts in code systems, or data element/data element concepts, or classes in class models.

ConceptMap

A clinical condition, problem, diagnosis, or other event, situation, issue, or clinical concept that has risen to a level of concern.

Condition

A record of a healthcare consumer’s  choices, which permits or denies identified recipient(s) or recipient role(s) to perform one or more actions within a given policy context, for specific purposes and periods of time.

Consent

Legally enforceable, formally recorded unilateral or bilateral directive i.e., a policy or agreement.
