What 58563 covers

A gynecologic surgeon passes a hysteroscope through the cervix to inspect the uterine cavity and ablate the endometrium using an appropriate operative method. The procedure is commonly performed in a hospital or ambulatory surgery setting for patients with abnormal uterine bleeding after clinical evaluation. It treats the uterine lining; it is distinct from removing a fibroid or ablating a uterine fibroid.

Report the procedure when the operative record supports endometrial ablation, rather than diagnostic inspection or treatment of a separate intrauterine target. The 0-day global period includes same-day preoperative and postoperative care. When related endoscopies are performed together, endoscopy family pricing applies. Modifier 50 is inappropriate. CMS permits co-surgeons; assistant-at-surgery payment requires documented medical necessity, and 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.

58563 billing questions

How does this differ from hysteroscopy with biopsy?

This code represents operative ablation of the endometrium. Use 58558 when the documented service is hysteroscopic tissue sampling or removal of endometrial tissue, rather than ablation.

Can diagnostic hysteroscopy be reported separately?

When the surgeon performs diagnostic inspection as part of the operative ablation, it is integral to that service. The record should identify the ablation performed, not just visualization.

Should modifier 50 be appended?

No. CMS identifies bilateral adjustment as inapplicable for this code; modifier 50 is inappropriate.

What is the global-period treatment?

The code has a 0-day global period. Same-day preoperative and postoperative care is included.

When can an assistant-at-surgery be paid?

Only when documentation supports medical necessity. CMS permits co-surgeons, but not team surgery, for this code.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
