What 58740 covers
A gynecologic surgeon uses 58740 to release pelvic adhesions that restrict or tether a fallopian tube or ovary, such as adhesions encountered during surgery for pelvic disease or after prior surgery. This code describes nonlaparoscopic adhesiolysis; laparoscopic release of adhesions involving these structures is reported with a different code. The operative note should identify the affected adnexal structures, describe the adhesions and the work performed, and explain why the release was a distinct part of the operation.
Because adhesiolysis is designated a separate procedure, do not report it when the release is incidental or integral to the primary operation. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

58740 billing questions
How is 58740 distinguished from 58660?
58740 is for nonlaparoscopic adhesiolysis involving a fallopian tube or ovary. Use 58660 for the laparoscopic approach.
Can 58740 be reported when adhesions are encountered during another operation?
Only when the release is a distinct service rather than incidental work integral to the primary operation. The operative note should document the structures involved and the separate work performed.
Should modifier 50 be used when adhesions involve both sides?
No. Modifier 50 is inappropriate for this code; report the service without a bilateral adjustment.
How does the multiple-procedure payment rule affect 58740?
When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction.
What postoperative care is included in the global period?
The 90-day global 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; team surgery is not permitted.
