Common Language Description

The CPT® Code 49080 refers to the procedure known as peritoneocentesis, abdominal paracentesis, or peritoneal lavage, which can be performed for both diagnostic and therapeutic purposes. This procedure involves the insertion of a catheter through a small incision in the abdominal wall into the peritoneal or abdominal cavity. The primary goal of this intervention is to either drain excess fluid or to perform a lavage, which is a washing out of the cavity. During a peritoneocentesis or abdominal paracentesis, the fluid that is collected is visually examined for signs of bleeding or other pathological conditions. This fluid is subsequently sent to a laboratory for further analysis, which may be reported separately. In cases where a peritoneal lavage is indicated, the procedure begins similarly with the drainage of the cavity, followed by the instillation of a saline solution. This saline is then withdrawn to help clear the cavity of any blood clots or debris. It is important to note that CPT® Code 49080 is designated for the initial procedure, while CPT® Code 49081 should be used for any subsequent procedures performed through a different access site on the same date of service. This distinction is crucial for accurate medical coding and billing.
