The Collection Payment Summary report tracks payments that fall within a selected Status category, either for a specific Patient or for all Patients. One of its uses is to report monies collected for Services with a Status of C (Collection) to your collection agency.
Example above shows the report filtered for all Patients, Status P, Date Range 08/01/13-08/22/13 (the first row has been expanded to show detail). Clicking on the Patient ID brings up the Patient record. Clicking on the Encounter ID brings up the Encounter.
