CPT® Code 89352

The CPT® Code 89352 refers to the procedure of thawing cryopreserved embryos, which are embryos that have been preserved through freezing for future use in assisted reproductive technologies. This process is essential for fertility treatments, allowing previously frozen embryos to be revived and utilized in procedures such as in vitro fertilization (IVF). During the thawing process, the cryopreserved embryos are carefully removed from their storage environment and subjected to warming techniques. These techniques may include the use of a controlled rate thawing chamber, a water bath, or simply allowing the embryos to reach room temperature. Once the embryos are thawed, a critical step involves the removal of cryoprotectants—substances used to protect the embryos during the freezing process. This is achieved through a series of culture mediums that gradually decrease the concentration of cryoprotectant, ensuring that the embryos are not exposed to harmful levels of these substances. After the cryoprotectant has been effectively removed, the embryos are placed in a suitable culture medium and incubated for a period of up to 24 hours. This incubation period is crucial as it allows for the assessment of the embryos' viability, specifically whether they resume development or exhibit cell division, which are indicators of their potential for successful implantation and pregnancy in subsequent assisted reproductive procedures.
