**Activity Diagram**

The Activity Diagram illustrates the Use Case flows graphically, and represents the flow of events and information between the actors. It also displays the main events/actions that are required for the data exchange and the role of each system in supporting the change.



Base Flow – When a Payer sends eMDR requests via a Payer Contractor
The Base Flow presents the step by step process of the information exchange depicted in the activity diagram (above). It indicates the actor who performs the action, the description of the event/action, and the associated inputs (records/data required to undertake the action) and outputs (records/data produced by actions taken).

The flow below is initiated when a Payer Contractor / Intermediary determines a need for additional documentation from a provider
