re: modifier use
Let me tell you how to answer this question.
Go to the CMS website and check on the global days for the service.
Look and see how many global days the procedure you've performed has.
If 0, then no modifier is needed.
If 10 or 90, and it is a staged or related procedure, use modifier 58.
