MedicationStatement is a statement at a point in time. The status is only representative at the point when it was asserted. The value set for MedicationStatement.status contains codes that assert the status of the use of the medication by the patient (for example, stopped or on hold) as well as codes that assert the status of the medication statement itself (for example, entered in error).
This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid.</td></tr><tr><td>MedicationStatement.category (category)</td><td><a href="http://hl7.org/fhir/R5/codesystem-concept-map-relationship.html#equivalent" title="equivalent">is equivalent to</a></td><td>MedicationStatement.category</td><td>Element `MedicationStatement.category` is mapped to FHIR R4 element `MedicationStatement.category` as `Equivalent`.</td></tr><tr><td>MedicationStatement.medication[x] (medication[x])</td><td><a href="http://hl7.org/fhir/R5/codesystem-concept-map-relationship.html#equivalent" title="equivalent">is equivalent to</a></td><td>MedicationStatement.medication[x]</td><td>Element `MedicationStatement.medication[x]` is mapped to FHIR R4 element `MedicationStatement.medication[x]` as `Equivalent`.

Likely references would be to MedicationRequest, MedicationDispense, Claim, Observation or QuestionnaireAnswers. The most common use cases for deriving a MedicationStatement comes from creating a MedicationStatement from a MedicationRequest or from a lab observation or a claim. it should be noted that the amount of information that is available varies from the type resource that you derive the MedicationStatement from.</td></tr><tr><td>MedicationStatement.reasonNotTaken (reasonNotTaken)</td><td><a href="http://hl7.org/fhir/R5/codesystem-concept-map-relationship.html#narrower" title="narrower">narrower</a></td><td>MedicationStatement.reasonCode</td><td>Element `MedicationStatement.reasonNotTaken` is mapped to FHIR R4 element `MedicationStatement.reasonCode` as `SourceIsNarrowerThanTarget`.</td></tr><tr><td>MedicationStatement.reasonCode (reasonCode)</td><td><a href="http://hl7.org/fhir/R5/codesystem-concept-map-relationship.html#equivalent" title="equivalent">is equivalent to</a></td><td>MedicationStatement.reasonCode</td><td>Element `MedicationStatement.reasonCode` is mapped to FHIR R4 element `MedicationStatement.reasonCode` as `Equivalent`.
