What 58520 covers
This service involves surgically closing a uterine wall disruption through an abdominal approach. It is most often performed by an obstetrician-gynecologist in an operating room when rupture occurs during labor or in another obstetric emergency; the operation may take place in the same setting as a cesarean delivery. The operative report should identify the rupture and describe the repair performed.
Report the code for the rupture repair itself, not simply because the uterus is inspected or an incision is closed during another operation. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate for this uterine repair. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.

58520 billing questions
When should this code be chosen instead of 58540?
Use this code for operative repair of a uterine rupture. Code 58540 describes uterine revision, not repair of an acute rupture.
Can this be reported when a cesarean delivery is also performed?
A rupture repair may occur during the same operation as a cesarean delivery. Document the distinct repair performed and assess the code combination under applicable coding edits.
Should modifier 50 be appended?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
