The procedure described is the retrieval of oocytes (eggs) by puncturing the ovarian follicle and aspirating the contents. CPT® code 58970, "Follicle puncture for oocyte retrieval, any method," accurately represents this service. The phrase "any method" indicates this code is appropriate regardless of the specific technique used for retrieval. The use of radiologic guidance is a distinct service and is reported separately (e.g., with 76948 for ultrasonic guidance). Therefore, 58970 is the correct code for the primary surgical procedure of oocyte retrieval.

A. 58976: This code is for the intrafallopian transfer of gametes, zygotes, or embryos, which is a different procedure that occurs after fertilization, not the initial egg retrieval.

B. 58974: This code describes the intrauterine transfer of an embryo, a subsequent step in the in vitro fertilization (IVF) process, not the oocyte retrieval itself.

C. 58999: This is an unlisted procedure code. It is incorrect to use this code because a specific CPT® code (58970) exists that accurately describes the service performed.
