0. MedicationRequest
Definition	An order or request for both supply of the medication and the instructions for administration of the medication to a patient. The resource is called "MedicationRequest" rather than "MedicationPrescription" or "MedicationOrder" to generalize the use across inpatient and outpatient settings, including care plans, etc., and to harmonize with workflow patterns.
Short	Ordering of medication for patient or group
Control	0..*
Is Modifier	false
Summary	false
Alternate Names	Prescription, Order
Invariants	dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (`contained.contained.empty()`) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource (`contained.where((('#'+id in (%resource.descendants().reference \| %resource.descendants().as(canonical) \| %resource.descendants().as(uri) \| %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()`) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (`contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()`) dom-5: If a resource is contained in another resource, it SHALL NOT have a security label (`contained.meta.security.empty()`) dom-6: A resource should have narrative for robust management (text.`div`.exists()) dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (contained.contained.empty()) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource (contained.where((('#'+id in (%resource.descendants().reference \| %resource.descendants().as(canonical) \| %resource.descendants().as(uri) \| %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()) dom-5: If a resource is contained in another resource, it SHALL NOT have a security label (contained.meta.security.empty()) dom-6: A resource should have narrative for robust management (text.`div`.exists())
2. MedicationRequest.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.
Short	Metadata about the resource
Control	0..1 This element is affected by the following invariants: ele-1
Type	Meta
Is Modifier	false
Must Support	true
Summary	true
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
4. MedicationRequest.meta.versionId
Definition	The version specific identifier, as it appears in the version portion of the URL. This value changes when the resource is created, updated, or deleted.
Short	Version specific identifier
Comments	The server assigns this value, and ignores what the client specifies, except in the case that the server is imposing version integrity on updates/deletes.
Control	0..1
Type	id
Is Modifier	false
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
Must Support	true
Summary	true
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
6. MedicationRequest.meta.lastUpdated
Definition	When the resource last changed - e.g. when the version changed.
Short	When the resource version last changed
Comments	This value is always populated except when the resource is first being created. The server / resource manager sets this value; what a client provides is irrelevant. This is equivalent to the HTTP Last-Modified and SHOULD have the same value on a read interaction.
Control	0..1
Type	instant
Is Modifier	false
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
Must Support	true
Summary	true
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
8. MedicationRequest.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.
Short	A set of rules under which this content was created
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.
Control	0..1
Type	uri
Is Modifier	true because This element is labeled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
Summary	true
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))

14. MedicationRequest.extension:multiplePrescription.extension:indicator.extension
Definition	An Extension May be used to represent additional information that is not part of the basic definition of the element. 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.
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.

74. MedicationRequest.extension:multiplePrescription.extension:id.value[x].type
Definition	A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.
Short	Description of identifier
Comments	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.

Definition	A unique ID that is identical across all partial prescriptions of a multiple prescription. The portion of the identifier typically relevant to the user and which is unique within the context of the system.
Short	Multiple Prescription IDThe value that is unique
Comments	If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

Binding	Unless not suitable, these codes SHALL be taken from Identifier Type Codeshttp://hl7.org/fhir/ValueSet/identifier-type\|4.0.1 (extensible to `http://hl7.org/fhir/ValueSet/identifier-type\|4.0.1`) A coded type for an identifier that can be used to determine which identifier to use for a specific purpose.
Type	CodeableConcept
Is Modifier	false
Summary	true
Requirements	Allows users to make use of identifiers when the identifier system is not known.
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
134. MedicationRequest.extension:patientID.value[x].value
Definition	Patienten-ID, welche bei der Verordnung bestimmter Arzneimittel angegeben werden kann. The portion of the identifier typically relevant to the user and which is unique within the context of the system.
Short	Patienten-IDThe value that is unique
Comments	If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

136. MedicationRequest.extension:patientID.value[x].period
Definition	Time period during which identifier is/was valid for use.
Short	Time period when id is/was valid for use
Comments	A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times"). Period is not used for a duration (a measure of elapsed time). See Duration.

Comments	Die KBV aktualisiert ihr "Schüsseltabellen"-Paket häufiger, als neue ePA-Versionen veröffentlicht werden. Allerdings übernehmen die E-Rezept-Clients und der E-Rezept-Fachdienst neue KBV-Paketversionen schnell nach deren Veröffentlichung und geben sie somit an den ePA-MedicationService weiter. Da der MedicationService möglicherweise an eine ältere Version des KBV-Pakets gebunden ist, würde er die weitergeleiteten E-Rezept-Daten ablehnen. Zukünftig wird der MedicationService in der Lage sein, auf die neuesten KBV-Paketversionen zu aktualisieren, ohne dass eine neue ePA-Version erforderlich ist. Da das E-Rezept tatsächlich die Codes gegen die neueste KBV-Paketversion prüft, wird der MedicationService keine "ungültigen" Codes erhalten, und die Clients können darauf vertrauen, dass die Daten des MedicationService mit der neuesten KBV-Paketversion übereinstimmen.

242. MedicationRequest.subject.identifier
Definition	An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference.
Short	Logical reference, when literal reference is not known
Comments	When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it. Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation\|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).

250. MedicationRequest.basedOn.reference
Definition	A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources.
Short	Literal reference, Relative, internal or absolute URL
Comments	Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation\|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).

Comments	For systems that do not have structured annotations, they can simply communicate a single annotation with no author or time. This element may need to be included in narrative because of the potential for modifying information. Annotations SHOULD NOT be used to communicate "modifying" information that could be computable.

Comments	There are examples where a medication request may include the option of an oral dose or an Intravenous or Intramuscular dose. For example, "Ondansetron 8mg orally or IV twice a day as needed for nausea" or "Compazine® (prochlorperazine) 5-10mg PO or 25mg PR bid prn nausea or vomiting". In these cases, two medication requests would be created that could be grouped together. The decision on which dose and route of administration to use is based on the patient's condition at the time the dose is needed.

Definition	Identifies the period time over which the supplied product is expected to be used, or the length of time the dispense is expected to last.
Short	Number of days supply per dispense
Comments	In some situations, this attribute may be used instead of quantity to identify the amount supplied by how long it is expected to last, rather than the physical quantity issued, e.g. 90 days supply of medication (based on an ordered dosage). When possible, it is always better to specify quantity, as this tends to be more precise. expectedSupplyDuration will always be an estimate that can be influenced by external factors.

0. MedicationRequest

Definition

An order or request for both supply of the medication and the instructions for administration of the medication to a patient. The resource is called "MedicationRequest" rather than "MedicationPrescription" or "MedicationOrder" to generalize the use across inpatient and outpatient settings, including care plans, etc., and to harmonize with workflow patterns.

Short Ordering of medication for patient or group
