Patient was seen for a problem visit in the office and needed to have an Endo bx done. During the Bx the provider saw a cervical polyp so a cervical bx was done as well. Anthem is denying 57500 stating "service is included in another service/procedure." I tried using modifier 51 to 57500 but still getting same denied reason. Any thoughts on using modifier 59 or should I appeal it?
