CPT® Code 57020

The procedure described by CPT® Code 57020 is known as colpocentesis, which is also referred to as culdocentesis. This procedure is categorized as a separate procedure, indicating that it is performed independently and is not part of a more comprehensive surgical intervention. During colpocentesis, the physician utilizes a tenaculum to grasp the posterior cervical lip, which allows for the elevation of the cervix. This maneuver is essential as it exposes the posterior vaginal wall, facilitating access to the area where fluid accumulation may occur. A needle and syringe are then carefully inserted into the vagina, with the needle tip positioned just below the posterior lip of the cervix. The vaginal wall is punctured at this location, enabling the physician to aspirate fluid from the posterior cul-de-sac, which is the space located behind the uterus. The aspirated fluid is subsequently sent to a laboratory for further analysis or culture, which may be reported separately. This procedure is typically performed to evaluate conditions such as pelvic inflammatory disease, ectopic pregnancy, or other gynecological issues where fluid accumulation is suspected.
