CPT® Code 47100

The procedure described by CPT® Code 47100 refers to a wedge biopsy of the liver, which is a surgical technique used to obtain a small, triangular section of liver tissue for diagnostic examination. This procedure is typically performed to investigate liver diseases or conditions that may not be identifiable through non-invasive imaging techniques. The biopsy allows for histological analysis, which can provide critical information regarding the presence of liver pathology, such as cirrhosis, hepatitis, or tumors. The surgical approach involves making an incision in the right subcostal region, which is the area beneath the rib cage on the right side of the body where the liver is located. During the procedure, the right rectus muscle is transected, and the oblique muscles are split to gain access to the liver. The sternum is retracted to facilitate visibility and access to the biopsy site. Once the appropriate area of the liver is identified, a wedge-shaped section is excised. After the tissue is removed, measures are taken to control any bleeding, the wound is irrigated to prevent infection, and the incision site is subsequently closed. This procedure is essential for obtaining tissue samples that can lead to accurate diagnoses and appropriate treatment plans for patients with liver-related health issues.
