CPT® Code 89272

The CPT® Code 89272 refers to the extended culture of oocyte(s) or embryo(s) for a duration of four to seven days. This procedure is typically performed after an initial culture period that is separately reportable for the first three days. During the extended culture phase, the oocytes or embryos are maintained in a specialized culture medium, which is essential for their continued development. The goal of this extended culture is to allow the embryos to progress to the blastocyst stage, which is characterized by the embryo reaching approximately eight cells. This stage is crucial for successful implantation and further development, making the extended culture an important step in assisted reproductive technology (ART) protocols.
