CPT® Code 49082

An abdominal paracentesis is a medical procedure that involves the insertion of a needle into the abdominal cavity to either diagnose or treat conditions associated with fluid accumulation. This procedure is particularly useful in identifying the underlying causes of fluid buildup, which may include infections, malignancies, or other pathological conditions. In cases where the fluid accumulation leads to discomfort, pain, or respiratory difficulties, the procedure can also serve a therapeutic purpose by alleviating these symptoms. During the procedure, the skin at the designated puncture site is first cleansed to minimize the risk of infection, followed by the administration of a local anesthetic to ensure patient comfort. A specialized paracentesis needle, which is connected to a syringe, is then carefully inserted into the abdominal cavity. Although imaging guidance can enhance the accuracy of needle placement, this specific CPT® code (49082) is designated for instances where the procedure is performed without such guidance. The aspirated fluid is subsequently examined visually for any signs of bleeding or other abnormalities. If the procedure is conducted for diagnostic reasons, only a small volume of fluid is extracted for laboratory analysis, whereas, for therapeutic purposes, the aspiration continues until the maximum amount of fluid is removed, providing relief to the patient.
