CPT® Code 47010

The CPT® Code 47010 refers to a surgical procedure known as hepatotomy, which is performed for the open drainage of an abscess or cyst located in the liver. This procedure can be executed in one or two stages, depending on the clinical situation. In a typical hepatotomy, a surgical incision is made to access the liver, allowing the surgeon to visualize the affected area. The most common approach involves a right subcostal incision, which may extend towards the xiphoid process or into the left subcostal region. This incision facilitates the transection of the right rectus muscle and the splitting of the oblique muscles, providing access to the liver. Once the liver is exposed, the surgeon locates the abscess or cyst, incises it, and drains its contents. Additionally, the abdomen is explored for any signs of peritonitis or other potential abscess sites. If the procedure is performed as a one-stage operation, a drain is placed within the abscess or cyst to facilitate further drainage, and the abdomen is subsequently closed around the drain. In cases where a two-stage procedure is necessary, the initial wound is left open to allow for continuous drainage, with closure occurring in a later surgical session once the infection has resolved. Although less common, a transpleural approach may be utilized if the abscess or cyst is situated in the upper posterior aspect of the liver; however, this method limits the ability to explore the abdomen thoroughly.
