Surgeon did hysteroscopy and polypectomy w/D&C. He also did endocervical curettage and I think CPT 58558 would cover these procedures. After he removed the hysteroscope he noted a white lesion on the cervix which he decided to do a biopsy on as well. Since the lesion biopsy wasn't part of the hysteroscopy, is there a CPT code I can use for this?
