CPT® Code 89346

The CPT® Code 89346 refers to the annual storage of oocyte(s), which are the female reproductive cells necessary for fertilization and subsequent development into embryos. This procedure is part of assisted reproductive technology (ART) and involves the preservation of oocytes for future use in fertility treatments. The storage process typically entails placing the oocytes in a controlled environment, where they are either submerged in liquid nitrogen or stored in the vapor phase. This method ensures that the oocytes are maintained at a constant and extremely low temperature of -270 degrees Celsius, which is crucial for preserving their viability over time. Regular monitoring of the liquid nitrogen levels and other storage conditions is essential to ensure that the required temperature is consistently maintained, thereby safeguarding the integrity of the stored oocytes. The duration of storage is determined by the specific protocols established by the fertility clinic or laboratory, allowing for flexibility based on individual patient needs. It is important to note that this code specifically pertains to the storage of oocytes, and there are separate codes for the storage of embryos, sperm/semen, and testicular or ovarian reproductive tissue, which are identified by their respective CPT® codes.
