CPT® Code 47015

The procedure described by CPT® Code 47015 involves a laparotomy, which is a surgical operation that entails making an incision in the abdominal wall to gain access to the abdominal cavity. This specific procedure focuses on the liver, where a parasitic cyst or abscess, such as those caused by amoebic or echinococcal infections, is treated. During the laparotomy, the surgeon typically makes an incision in the right subcostal area, which may be extended into the left subcostal region or upwards towards the xiphoid process, depending on the location of the cyst or abscess. The surgical approach requires the transection of the right rectus muscle and splitting of the oblique muscles to adequately expose the liver for inspection. Once the liver is accessed, the surgeon identifies the parasitic cyst or abscess and punctures it to facilitate the aspiration process. This involves using a needle or catheter to suction out the fluid and debris contained within the cyst or abscess pocket. In cases of amebic infections, the procedure may not include an injection following aspiration, as treatment is often managed with oral antibiotics. Conversely, for echinococcal infections, a protoscolicidal agent, such as hypertonic saline or ethanol, is injected into the cyst pocket and left for a duration of approximately 15 minutes before being reaspirated. This method aims to effectively eliminate the parasitic infection while minimizing complications associated with the cyst or abscess.
