I work for an Urgent Care, and I'm a little confused about modifier -59. When we do a laceration repair, say 12001, we almost always do a tetanus vaccination. I'm being told that I need to bill my E/M code with -25, then 12001, then 90471-59, and 90715. Is that correct? I'm also being told that -59 is required if there are any two non-lab procedure codes used with the E/M. For example, a laceration repair and a breathing treatment. Can someone clear this up for me? Thank you.
