What 58573 covers
A gynecologic surgeon removes the uterus and cervix laparoscopically and also removes one or both fallopian tubes, one or both ovaries, or both types of adnexa. The code is for a uterine specimen weighing more than 250 grams. A common clinical setting is surgery for a markedly enlarged, fibroid uterus causing bleeding or bulk symptoms. The procedure is typically performed in a hospital operating room or ambulatory surgery center.
Select the code when the operative report supports a total laparoscopic approach, removal of adnexal tissue, and a uterine weight over 250 grams. Document the structures removed and the specimen weight; report the procedure once, not separately for each tube or ovary. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When other procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made, co-surgeons are permitted, and team surgery is not permitted.

- 58571Laparoscopic hysterectomyUterus 250 g or less, adnexa removed

58573 billing questions
How does this differ from 58572?
Both describe total laparoscopic hysterectomy for a uterus over 250 grams. Use 58573 when one or more fallopian tubes or ovaries are also removed; 58572 is for the hysterectomy without that adnexal removal.
Is the tube or ovary removal billed separately?
Removal of one or more fallopian tubes or ovaries is included in this procedure. Report the code once, whether one or several of those structures are removed.
Should modifier 50 be added when both sides are removed?
No. CMS indicates that bilateral adjustment does not apply and modifier 50 is inappropriate for this code, including when both sides are treated.
What documentation supports the over-250-gram code?
The operative report should establish the laparoscopic total hysterectomy and identify the tube or ovary tissue removed. Document the uterine specimen weight to support selection over the 250-gram threshold.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period. CMS also applies its standard multiple-procedure reduction when other procedures are performed in the same session.
Can an assistant or co-surgeon be reported?
CMS allows payment for an assistant at surgery and permits co-surgeons. Team surgery is not permitted for this code.
