What 58970 covers
A reproductive endocrinologist or other qualified physician typically retrieves oocytes after ovarian stimulation, commonly using a needle guided by transvaginal ultrasound to aspirate fluid from ovarian follicles. The procedure is performed as part of an assisted reproduction cycle; the collected follicular fluid and oocytes then go to the embryology laboratory for identification and related laboratory work.
Report the retrieval procedure, not a separate unit for each oocyte collected. The record should support the follicular aspiration and its purpose in the treatment cycle. The 0-day global period includes same-day preoperative and postoperative care. When other procedures subject to the multiple procedure rule occur in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. An assistant is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

58970 billing questions
How is this different from embryo transfer?
Oocyte retrieval collects eggs from ovarian follicles. Embryo transfer (58974) places an embryo into the uterus later in the treatment process.
Is retrieval reported once per oocyte?
Report the retrieval procedure for the session, rather than assigning a separate unit for each oocyte collected.
Can modifier 50 be used for retrieval from both ovaries?
No. CMS identifies bilateral adjustment as inappropriate for this service; modifier 50 should not be used.
Is same-day recovery care included?
Yes. The 0-day global period includes same-day preoperative and postoperative care.
When is an assistant at surgery payable?
Only when the record documents medical necessity. Co-surgeons and team surgery are not permitted for this service.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other eligible procedures are paid at 50%.
