Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
