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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

59136 billing questions

What distinguishes 59136 from surgery for a tubal ectopic pregnancy?

Use 59136 when the implantation is interstitial, in the portion of the tube that passes through the uterine wall. Tubal or ovarian ectopic pregnancy surgery is represented by other codes, selected according to the procedure and approach.

What operative documentation supports 59136?

The operative report should identify the interstitial uterine implantation and describe the surgical treatment performed. Documentation should distinguish this site from tubal or ovarian, cervical, and abdominal ectopic pregnancy.

What postoperative care is included in the global period?

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?

No. CMS identifies bilateral adjustment as inappropriate for this code.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. Co-surgeons and team surgery are not permitted under the CMS rules for this code.
