What 58555 covers

A gynecologist passes a hysteroscope through the cervix to inspect the endometrial cavity, for example when evaluating abnormal uterine bleeding or a suspected intracavitary abnormality. The procedure may be performed in an office or outpatient surgical setting. This code represents diagnostic visualization, not hysteroscopic sampling or treatment of a finding.

Report it when diagnostic inspection is the hysteroscopic service performed; document the indication, findings, and whether any operative work was done. Because it is a separate procedure, diagnostic inspection is generally not separately reported when it is part of a hysteroscopic biopsy or treatment. The 0-day global period includes same-day preoperative and postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are reduced by 50%. Bilateral adjustment is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons are permitted, while 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.

58555 billing questions

When should 58555 be chosen instead of 58558?

Use 58555 for diagnostic cavity inspection without sampling or tissue removal. When hysteroscopy includes endometrial sampling or biopsy, 58558 describes the operative service.

Can 58555 be reported with an operative hysteroscopy code?

The diagnostic inspection is generally integral to hysteroscopic biopsy or treatment and is not separately reported for the same procedure. Report the code describing the operative work performed.

What documentation supports 58555?

Document the clinical reason for evaluating the cavity, the hysteroscopic findings, and that no biopsy or therapeutic work was performed.

Should modifier 50 be appended?

No. CMS identifies bilateral adjustment as inappropriate for this code.

How are multiple procedures in the same session paid?

The highest-valued procedure is paid in full, and the other procedures are subject to the standard 50% multiple-procedure reduction.

When is assistant-at-surgery payment allowed?

Payment for an assistant at surgery requires documentation of medical necessity. CMS permits co-surgeons but does not permit 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.
