0. Extension
Definition	R5: `EpisodeOfCare.reason` (new:BackboneElement) Optional Extension Element - found in all resources.
Short	R5: The list of medical reasons that are expected to be addressed during the episode of care (new)Optional Extensions Element
Comments	Element `EpisodeOfCare.reason` has a context of EpisodeOfCare based on following the parent source element upwards and mapping to `EpisodeOfCare`. Element `EpisodeOfCare.reason` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). The reason communicates what medical problem the patient has that should be addressed during the episode of care. This reason could be patient reported complaint, a clinical indication that was determined in a previous encounter or episode of care, or some planned care such as an immunization recommendation. In the case where you have a primary reason, but are expecting to also address other problems, you can list the primary reason with a use code of 'Chief Complaint', while the other problems being addressed would have a use code of 'Reason for Visit'. Examples: * pregnancy would use HealthcareService or a coding as the reason * patient home monitoring could use Condition as the reason
Control	0..* This element is affected by the following invariants: ele-1
Is Modifier	false
Invariants	ele-1: All FHIR elements must have a @value or children (`hasValue() \| (children().count() > id.count())`) ext-1: Must have either extensions or value[x], not both (`extension.exists() != value.exists()`) ele-1: All FHIR elements must have a @value or children (hasValue() \| (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
2. Extension.extension
Definition	An Extension May be used to represent additional information that is not part of the basic definition of the element. In order 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.
Short	ExtensionAdditional Content defined by implementations
Comments	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.

XML Format	In the XML format, this property is represented as an attribute.
26. Extension.extension:value.extension:_datatype.extension
Definition	May be used to represent additional information that is not part of the basic definition of the element. In order 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.
Short	Additional Content defined by implementations
Comments	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.
