How often do reorganized companies refile?

Surprisingly often.  But the rates vary drastically from court to court and from year to year.   The data on this website are only for refilings that occur within five years after confirmation of the company's plan.

To get a simple percentage, in the first step, variable A. Years check the radio button for "disposed of in these years" and then select years that do not include any of the most recent five.  Then for variable K. Refiling, check only the categories Company emerged and refiled and Company emerged but did not refile.  In the second step, check only the boxes for Company Names and Frequency.  In the third step, select K. Refiling within five years.  Submit your query by clicking on the Submit Query button on the bottom of the page.  The output will show you the percentage of emerging companies that have refiled in the years you selected.

To get the refiling rate for a particular court, follow the steps above, and also check that court city in step 1, B. Filing Cities.
