What 58542 covers
A gynecologic surgeon removes the uterine body laparoscopically and leaves the cervix in place. This code is for cases that also include removal of at least one fallopian tube and/or ovary, such as a tube removed during hysterectomy for symptomatic fibroids or abnormal uterine bleeding. The procedure is generally performed in a hospital operating room or an ambulatory surgery setting. The uterine weight determines whether this code or a higher-weight code in the family applies.
Report the code when the operative record supports the supracervical approach, adnexal removal, and uterine weight of 250 g or less; pathology documentation can help substantiate weight. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. 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 for this code. CMS permits assistant-at-surgery and co-surgeon payment; team surgery is not permitted.

- Both are laparoscopic supracervical hysterectomies for a uterus 250 g or less. Choose 58542 when one or more tubes and/or ovaries are removed; 58541 describes the procedure without that removal.
- 58544Laparoscopic hysterectomySupracervical, uterus over 250 g
- Both include laparoscopic supracervical hysterectomy with adnexal removal. The distinction is uterine weight: 58544 is for a uterus weighing more than 250 g.
- 58571Laparoscopic hysterectomyUterus 250 g or less, adnexa removed
- Both describe laparoscopic hysterectomy with adnexal removal for a uterus 250 g or less. Use 58571 when the cervix is removed; 58542 leaves it in place.
58542 billing questions
How does this differ from 58541?
58542 includes removal of one or more fallopian tubes and/or ovaries during the supracervical hysterectomy. Use 58541 when the uterus is 250 g or less and no tube or ovary is removed.
Does the cervix remain?
Yes. This is a supracervical hysterectomy: the uterine body is removed and the cervix is retained.
Can the tube or ovary removal be billed separately?
Removal of one or more tubes and/or ovaries is part of the service represented by 58542. Do not separately report the same adnexal removal as though it were outside this hysterectomy service.
What supports the 250 g threshold?
The operative and pathology records should support the uterine weight and the laparoscopic supracervical approach. Use the higher-weight code when the uterus weighs more than 250 g.
Can an assistant or co-surgeon be reported?
CMS permits assistant-at-surgery and co-surgeon payment for this code. Team surgery is not permitted.
Should modifier 50 be appended?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate for the service.
Where these rates come from

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.
