Hello, looking for insight to the billing of procedure 17250 for umbilical cauterization along with E/M visits such as 99213 or 99214. I've tried to review the global surgery packet but did not see an example of why the billing would not be permitted when it was medically necessary. In my example, what is the proper billing practice if the patient has had to have this completed multiple times within a months time. The latest claims E/M was denied by BCBS, despite submitting records showing the support of modifier 25 attached to the E/M. Any info would be appreciated. Additional note is more than one visit with cauterization was performed within the 10 day rule and one outside of the 10th day.
