I am the owner of a small private practice outpatient physical therapy clinic and collect weekly summary stats for the office. Over the weekend (closed for business at this time) I generated a report titled "Collections by Rendering Facility" for the week and was provided with a $ figure. I re-ran the report on Monday of the following week, prior to start of business, and the figure was ~ $700 less than what it was originally. Further investigation into the system log revealed that the biller deleted a batch of applied payments over the weekend which explained the discrepancy according to a rep from our EHR company that I spoke with. He was however unable to provide me with an answer as to why such an action would ever be carried out.
