Encounter.id | |
Definition | The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. |
Cardinality | 0...1 |
Type | string |
Summary | True |
Comments | The only time that a resource does not have an id is when it is being submitted to the server using a create operation. |
Encounter.meta | |
Definition | The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource. |
Cardinality | 0...1 |

Encounter.implicitRules | |
Definition | 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. |
Cardinality | 0...1 |
Type | uri |
Modifier | True |
Summary | True |
Comments | 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. |

Encounter.language | |
Definition | The base language in which the resource is written. |
Cardinality | 0...1 |
Type | code |
Binding | A human language. |
Comments | Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute). |
Invariants |

Mappings |
|
Encounter.text | |
Definition | A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety. |
Cardinality | 0...1 |
Type | Narrative |
Alias | narrative, html, xhtml, display |
Comments | Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later. |

Encounter.contained | |
Definition | 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. |
Cardinality | 0...* |
Type | Resource |
Alias | inline resources, anonymous resources, contained resources |
Comments | 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. |
Mappings |
|
Encounter.extension | |
Definition | 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 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. |

Definition | The class history permits the tracking of the encounters transitions without needing to go through the resource history. This would be used for a case where an admission starts of as an emergency encounter, then transitions into an inpatient scenario. Doing this and not restarting a new encounter ensures that any lab/diagnostic results can more easily follow the patient and not require re-processing and not get lost or cancelled during a kind of discharge from emergency to inpatient. |

class
This element SHALL be present and the following values must be used. However, an alternative CodeSystem may be used if no suitable code is listed below. The binding is to the International FHIR ValueSet v3 ActEncounterCode, and is shown expanded here due to the complexity of included and excluded codes.
Code | Display | Definition |
---|---|---|
AMB | ambulatory | A comprehensive term for health care provided in a healthcare facility (e.g. a practitioners office, clinic setting, or hospital) on a nonresident basis. The term ambulatory usually implies that the patient has come to the location and is not assigned to a bed. Sometimes referred to as an outpatient encounter. |
EMER | emergency | A patient encounter that takes place at a dedicated healthcare service delivery location where the patient receives immediate evaluation and treatment, provided until the patient can be discharged or responsibility for the patient's care is transferred elsewhere (for example, the patient could be admitted as an inpatient or transferred to another facility.) |
FLD | field | A patient encounter that takes place both outside a dedicated service delivery location and outside a patient's residence. Example locations might include an accident site and at a supermarket. |
HH | home health | Healthcare encounter that takes place in the residence of the patient or a designee |
IMP | inpatient encounter | A patient encounter where a patient is admitted by a hospital or equivalent facility, assigned to a location where patients generally stay at least overnight and provided with room, board, and continuous nursing service. |
ACUTE | inpatient acute | An acute inpatient encounter. |
NONAC | inpatient | non-acute Any category of inpatient encounter except 'acute' |
OBSENC | observation encounter | An encounter where the patient usually will start in different encounter, such as one in the emergency department (EMER) but then transition to this type of encounter because they require a significant period of treatment and monitoring to determine whether or not their condition warrants an inpatient admission or discharge. In the majority of cases the decision about admission or discharge will occur within a time period determined by local, regional or national regulation, often between 24 and 48 hours. |
PRENC | pre-admission | A patient encounter where patient is scheduled or planned to receive service delivery in the future, and the patient is given a pre-admission account number. When the patient comes back for subsequent service, the pre-admission encounter is selected and is encapsulated into the service registration, and a new account number is generated. Usage Note: This is intended to be used in advance of encounter types such as ambulatory, inpatient encounter, virtual, etc. |
SS | short stay | An encounter where the patient is admitted to a health care facility for a predetermined length of time, usually less than 24 hours. |
VR | virtual | A patient encounter where the patient and the practitioner are not in the same physical location. Examples include telephone conference, email exchange, robotic surgery, and televideo conference. |
