What 58120 covers
A gynecologist dilates the cervix and uses a curette to sample or remove tissue from the uterine cavity. The procedure may be diagnostic, such as evaluating abnormal uterine bleeding when office sampling is inadequate or not feasible, or therapeutic when curettage is performed to address bleeding. It is performed in settings such as an operating room, ambulatory surgery center, or, in selected cases, an office.
Report the service when the documented procedure includes cervical dilation and uterine curettage; a biopsy without dilation is a different service. The record should identify the indication, the work performed, and relevant findings or specimens. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

58120 billing questions
How is this different from 58100?
58120 includes cervical dilation and curettage of the uterine cavity. 58100 is endometrial sampling without cervical dilation.
When would 58558 be a better fit?
Use 58558 when the physician performs operative hysteroscopy with endometrial sampling or polyp removal. Do not separately report a D&C that is part of that hysteroscopic service.
Can the pathology examination be reported separately?
The laboratory may separately report its examination of submitted tissue. The physician's D&C service and the laboratory's pathology service are distinct services.
Should modifier 50 be appended?
No. The bilateral adjustment does not apply, and modifier 50 is inappropriate for this service.
How does the multiple-procedure rule affect payment?
For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction.
Are assistant or co-surgeon services payable?
Medicare does not pay an assistant at surgery for 58120. Co-surgeons and team surgery are not permitted.
