What 58605 covers
This service interrupts one or both fallopian tubes after childbirth through an abdominal or vaginal approach. An obstetrician-gynecologist typically performs it in a hospital setting; after vaginal delivery, an abdominal incision may be used to access the tubes. The operative report should establish that the procedure occurred postpartum and document the approach and work performed. When the tube procedure is done during cesarean delivery, code 58611 is the more relevant code to evaluate.
Report 58605 for the postpartum circumstance, distinguishing it from 58600 when the procedure is not postpartum. CMS prices the code as bilateral, so modifier 50 does not increase payment. A 90-day global period includes the day-before preoperative visit and related postoperative care during the following 90 days. 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 multiple procedure reduction. Assistant-at-surgery payment may be allowed; co-surgeons and team surgery are not permitted.
