Are all patients active? When would they be inactive?

From TherapyCharts

“Active” reflects a patient who is coming at regular intervals for therapy. All patients that are marked “active” show in the patient list feature. To help clinicians only have the most relevant information at their fingertips, we suggest marking the patients who are no longer being seen "inactive" such that they will not show by default on lists nor count against client loads for our part-time members.
