I guess my first question would be in addition to what??
Second question is what is being resected??
In my practice, the physicians use the myosure to either resect a polyp, or a fibroid.
If polyp, 58558 covers it all
58558 - Hysteroscopy, surgical; with sampling (biopsy) of endometrium and/or polypectomy, with or without D & C
If fibroid, 58561.
58561 - Hysteroscopy, surgical; with removal of leiomyomata
FYI - It's usually helpful if you put what you think the codes might be, to show your thought process so others can assist.
