Gynecology
About 58558: Hysteroscopic endometrial sampling or polypectomy
Report this service when a clinician uses hysteroscopy to sample the endometrium or remove an endometrial polyp, with or without curettage.
A gynecologist passes a hysteroscope through the cervix to inspect the uterine cavity and obtain endometrial tissue or remove a polyp under direct visualization. The procedure is commonly performed in an operating room or ambulatory surgery center for abnormal uterine bleeding, a suspected endometrial lesion, or a polyp identified on imaging or earlier evaluation. Tissue is typically sent for pathology. The code also covers curettage performed with the hysteroscopic service.
Choose this code when the operative hysteroscopy includes endometrial sampling or polypectomy, rather than diagnostic inspection alone or removal of a submucosal fibroid. Document the indication, hysteroscopic findings, tissue sampling or polyp removal, and any curettage performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing applies. Modifier 50 is inappropriate. Assistant-at-surgery services are not paid; co-surgeons are permitted, while team surgery is not permitted.

58558 billing questions
When should I report this instead of diagnostic hysteroscopy?
Report 58558 when the hysteroscopy includes endometrial sampling or polyp removal. Diagnostic inspection alone is represented by 58555.
Can curettage be reported separately?
Curettage performed with this hysteroscopic service is included in the code. The descriptor covers the service with or without curettage.
Can I report a separate diagnostic hysteroscopy during the same session?
Do not report diagnostic hysteroscopy as a separate service when it is part of the operative hysteroscopy. CMS endoscopy family pricing applies when related endoscopies are performed together.
Should modifier 50 be used for bilateral findings?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What should the operative note support?
Document the clinical indication, hysteroscopic findings, whether endometrial tissue was sampled or a polyp was removed, and any curettage performed.
Are assistant or co-surgeon services payable?
CMS does not pay an assistant at surgery for this service. Co-surgeons are permitted; team surgery is not.
