Patient had a Laparoscopy, surgical with removal of bilateral salpingectomy for sterilization. According to the CMS, Medicare does not pay for elective. sterilization. My dilemma is 58661 for this procedure is covered for medical reasons, just not for elective sterilization. No ABN was obtained. This patient has medicaid as secondary that does cover elective sterilization. Would it be correct to add modifier GY in this case?
