Be sure your documentation supports the re-exam and use modifier -25 to indicate it's a separate service. I don't think there is a max number of procedures you can BILL, but there may be a max number that the insurance will PAY. In the Worker's Comp arena there is a cascade (they reduce the allowed by 25% per procedure to a max of 4 procedures).
I'm curious WHY there are so many procedures in one visit, but I realize that each practice is different. On a re-exam day you may just want to do the exam PRIOR to any therapies or modalities and adjustment. The ROM's will be more accurate. The dx codes may not change, but if portions of the injury have resolved, that should be noted in the record and on the report (if one gets generated for the re-exam).
