What 59136 covers
Code 59136 represents operative treatment of an ectopic pregnancy implanted in the interstitial portion of the fallopian tube, where it traverses the uterine wall. An obstetrician-gynecologist typically performs the procedure in an operating room; treatment may involve removing the ectopic tissue and repairing the uterine wall. The operative report should establish the interstitial uterine site rather than a tubal or ovarian, cervical, or abdominal implantation.
Select this code by implantation site and the procedure performed, not simply because an ectopic pregnancy is present; other sites and laparoscopic treatment have distinct codes. Document operative findings and the treatment completed. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and related postoperative care through day 90. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

The 90-day major-surgery global period includes the day-before preoperative visit and related postoperative care through day 90.
Can modifier 50 be used for bilateral treatment?
