What 58140 covers
A gynecologic surgeon removes uterine leiomyomas through an abdominal approach while preserving the uterus. The operation may be performed for symptoms such as heavy menstrual bleeding or pelvic pressure, or when fibroids affect reproductive plans. It includes removal of one to four intramural fibroids with a combined weight of 250 g or less, and can also cover removal of surface fibroids. This is generally performed in a hospital or other surgical facility.
Select this code based on the abdominal approach and the documented number, location, and total weight of the fibroids removed. The operative report should support the intramural count and weight, or describe the surface fibroids removed. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted. Modifier 50 is not appropriate for this uterine procedure.

How to choose

- This is the vaginal-approach myomectomy code. Use 58140 when the surgeon removes fibroids through an abdominal approach.
- 58150Hysterectomy
- 58150 reports total hysterectomy, which removes the uterus; 58140 reports fibroid removal with the uterus preserved.
58140 billing questions
When is 58140 selected instead of 58146?
Use 58140 for an abdominal approach when there are one to four intramural fibroids weighing 250 g or less in total, or when surface fibroids are removed. 58146 describes a greater intramural fibroid burden.
How does the vaginal approach affect code selection?
58145 is the related vaginal-approach myomectomy code. Select based on the operative approach rather than treating the two codes as interchangeable.
What documentation supports 58140?
The operative report should identify the abdominal approach and describe the fibroids removed. For intramural fibroids, document their number and combined weight; for surface fibroids, document their location and removal.
Does the 90-day global period include routine postoperative care?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, while team surgery is not permitted.
Can modifier 50 be added for multiple fibroids?
No. Modifier 50 is inappropriate for this uterine procedure; multiple fibroids are addressed through the code’s fibroid-burden criteria.
