This class represents a list of medications that the patient is taking. This list may contain information from prescription data (Pharmacy Requests), pharmacy data (Pharmacy Promises) and/or Patient-Reported Medications. Because the list may be an aggregation of data from multiple sources, duplicate information may potentially exist. Note that this class could be populated as a result of a medication reconciliation process. Details of such a process are not yet modeled in the FHIM.
