What 58561 covers

The surgeon passes a hysteroscope through the cervix to visualize and remove uterine leiomyomas from the uterine cavity. This is commonly performed by a gynecologist in an operating room or ambulatory surgery setting for patients with intracavitary fibroids, including those associated with abnormal uterine bleeding or fertility concerns. The operative inspection is part of the removal service.

Report this code when the operative hysteroscopy removes leiomyoma tissue; document the fibroid findings and the removal performed. It has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing applies. CMS does not apply a bilateral adjustment, and modifier 50 is inappropriate. Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons are permitted; team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

58558HysteroscopyBiopsy or polyp removal
Choose 58561 for removal of uterine leiomyoma tissue. Choose 58558 for hysteroscopic endometrial sampling or polyp removal.
58545Laparoscopic myomectomyLimited fibroid burden
Both address myomas, but 58561 uses a hysteroscope through the cervix; 58545 describes laparoscopic myomectomy.
58555HysteroscopyDiagnostic only
Code 58555 is for diagnostic hysteroscopy alone. When the same session proceeds to myoma removal, the diagnostic inspection is part of the operative service.
58560HysteroscopyUterine septum resection
Code 58560 treats a uterine septum hysteroscopically; 58561 removes uterine leiomyoma tissue.

58561 billing questions

When should this code be chosen over 58558?

Use 58561 when hysteroscopy removes uterine leiomyoma tissue. Code 58558 describes hysteroscopic sampling or polyp removal, rather than myoma removal.

Can diagnostic hysteroscopy be reported separately?

The inspection used to locate a myoma during the same session is part of the operative hysteroscopy. Do not separately report 58555 for that diagnostic inspection.

Is modifier 50 appropriate for multiple or bilateral myomas?

No. CMS does not apply a bilateral adjustment to this code, and modifier 50 is inappropriate.

When is an assistant at surgery payable?

CMS pays an assistant at surgery only when the record documents medical necessity.

How does this differ from laparoscopic myomectomy?

This code is for removal through a hysteroscope passed through the cervix. Code 58545 describes myomectomy performed laparoscopically.

What is included in the global period?

The global period is 0 days. Same-day preoperative and postoperative care is included.
