What 58559 covers

A gynecologist or other qualified surgeon uses a hysteroscope passed through the cervix to visualize and divide scar bands within the uterine cavity. This treatment may be performed for intrauterine adhesions that distort the cavity, including adhesions associated with Asherman syndrome. The procedure is commonly done in a hospital or ambulatory surgery center; it may also be performed in an appropriately equipped office setting.

Select this code when the operative work is lysis of intrauterine adhesions, not simply diagnostic inspection or treatment of a septum, myoma, polyp, or retained foreign body. The operative report should identify the adhesions and document the hysteroscopic treatment 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. CMS does not pay an assistant at surgery; co-surgeons are permitted, while team surgery is not.

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

58555HysteroscopyDiagnostic only
Use 58555 for diagnostic cavity inspection without operative treatment. Adhesion division is reported with 58559, and the same-session inspection is not separately reported.
58558HysteroscopyBiopsy or polyp removal
Use 58558 when the hysteroscopic work is biopsy or polypectomy. Use 58559 when the operative target is intrauterine adhesions.
58560HysteroscopyUterine septum resection
Use 58560 for hysteroscopic treatment of a uterine septum; 58559 addresses adhesions within the cavity.
58561Myoma removalHysteroscopic approach
Use 58561 when hysteroscopy removes a uterine myoma. Adhesion lysis, rather than myoma removal, supports 58559.

58559 billing questions

How is this different from diagnostic hysteroscopy?

This code is for operative division of adhesions inside the uterine cavity. Diagnostic hysteroscopy alone is reported with 58555; same-session diagnostic inspection is generally part of the operative hysteroscopy.

Can diagnostic hysteroscopy be billed separately on the same date?

Do not separately report 58555 for the inspection that guides the same-session adhesion treatment. The operative service includes visualization of the cavity.

Is the code reported per adhesion?

The code represents the hysteroscopic lysis service, not a unit for each adhesion or scar band. Document the findings and the treatment performed.

Should modifier 50 be used for adhesions on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 is not used.

What are the assistant and co-surgeon rules?

CMS does not pay an assistant at surgery for this service. Co-surgeons are permitted, but team surgery is not.

What global-period care is included?

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