What 58825 covers
Ovarian transposition surgically moves one or both ovaries away from the area expected to receive pelvic radiation. Gynecologic surgeons typically perform it before radiation treatment for pelvic cancers when preserving ovarian function is part of the treatment plan. The operative report should identify the ovary or ovaries moved and document the transposition performed.
Report 58825 for the transposition procedure, not for ovarian cyst or abscess drainage, or for later radiation services. CMS assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. If 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. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose
- 58940Oophorectomy

- 58720Salpingo-oophorectomy
- This code describes partial or complete salpingo-oophorectomy. It represents removal of the tube and ovary, not ovarian relocation.
- 58661Adnexal removal
- This laparoscopic code describes removal of adnexal structures. It is distinct from transposing an ovary without removing it.
58825 billing questions
When is 58825 appropriate instead of an ovarian removal code?
Use 58825 when the surgeon relocates an ovary or ovaries rather than removing them. Oophorectomy and salpingo-oophorectomy codes describe removal procedures.
Should modifier 50 be added when both ovaries are transposed?
No. CMS identifies bilateral adjustment as inappropriate for 58825; the code's descriptor and anatomy do not support modifier 50.
Does 58825 include related postoperative visits?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How does CMS handle 58825 with another procedure in the same session?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be allowed. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
What documentation supports reporting 58825?
The operative report should establish that an ovary or ovaries were surgically transposed and identify the work performed. Document the clinical plan for moving the ovaries away from the pelvic radiation field when applicable.
