If the element is present, it must have either a @value, an @id, or extensions Identifiers associated with this medication request that are defined by business processes and/or used to refer to it when a direct URL reference to the resource itself is not appropriate. They are business identifiers assigned to this resource by the performer or other systems and remain constant as the resource is updated and propagates from server to server. Whenever the medication request is being issued because of another request, eg. a procedure that is being planned (ServiceRequest) and MedicationRequests are known to be needed, this element documents those requests. Reference to an order/prescription that is being replaced by this MedicationRequest. A shared identifier common to multiple independent Request instances that were activated/authorized more or less simultaneously by a single author. The presence of the same identifier on each request ties those requests together and may have business ramifications in terms of reporting of results, billing, etc. E.g. a requisition number shared by a set of lab tests ordered together, or a prescription number shared by all meds ordered at one time. A code specifying the current state of the order. Generally, this will be active or completed state. Captures the reason for the current state of the MedicationRequest. The date (and perhaps time) when the status was changed. Whether the request is a proposal, plan, or an original order. An arbitrary categorization or grouping of the medication request.

Indicates the type of performer of the administration of the medication. The specified desired performer of the medication treatment (e.g. the performer of the medication administration). For devices, this is the device that is intended to perform the administration of the medication. An IV Pump would be an example of a device that is performing the administration. Both the IV Pump and the practitioner that set the rate or bolus on the pump can be listed as performers. The intended type of device that is to be used for the administration of the medication (for example, PCA Pump).

Indicates whether or not substitution can or should be part of the dispense. In some cases, substitution must happen, in other cases substitution must not happen. This block explains the prescriber's intent. If nothing is specified substitution may be done.
