Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision procedures in the hepatobiliary system and pancreas involve cutting away a piece of the liver, gallbladder, bile ducts, or pancreas without replacing that tissue. Common examples include a liver wedge or needle biopsy to sample suspicious tissue, partial removal of a diseased segment of liver, excision of a bile duct stricture or mass, and partial (distal or segmental) pancreatectomy for a tumor or damaged tissue. The point is either to diagnose a condition by examining tissue under a microscope or to remove a localized problem while leaving the rest of the organ intact.
Surgeons choose excision over more extensive removal when disease is confined enough that taking out the whole organ isn't necessary, or when a biopsy alone will answer a diagnostic question. Because the liver and pancreas both have some capacity to function with less tissue, excision can control a tumor, cyst, or abscess while preserving as much organ function as possible.
Recovery and follow-up depend on how much tissue was removed and which organ was involved, with pancreatic excisions in particular carrying a higher risk of digestive or blood sugar changes afterward.
Anatomy & Axis Detail
Liver, Left Lobe
The left lobe of the liver is smaller than the right and lies across the midline, extending toward the spleen and adjacent to the stomach, which makes it more readily accessible for resection in some approaches. Excision confined to left lobe tissue, such as a left lateral sectionectomy or left hepatectomy, is used for tumors, cysts, or biopsy of lesions localized to this portion of the gland, and this segment is also a common source for living donor liver transplantation given its more manageable size and vascular anatomy. As with any hepatic resection, control of the left hepatic vein and portal branches supplying the lobe is central to the procedure. Coding depends on the operative note clearly indicating the excised tissue originated from the left rather than right lobe.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
Qualifier: Hand-Assisted
This qualifier indicates that a laparoscopic or endoscopic procedure was performed with the surgeon's hand inserted through a separate incision to provide tactile feedback and manual assistance alongside the instruments. It distinguishes hand-assisted minimally invasive technique from standard laparoscopic approaches performed with instruments alone.
Coding & Documentation
The coder needs documentation naming the specific body part excised (e.g., left lobe of liver, common bile duct, body of pancreas) and confirmation that only a portion, not the whole structure, was taken. Operative notes should distinguish a true cutting excision from a biopsy obtained by other means, and should specify the approach (open, percutaneous, or via endoscope/laparoscope). A frequent error is coding a needle or forceps biopsy as Extraction rather than Excision; PCS classifies biopsies as Excision regardless of instrument. Another common mix-up is selecting Resection when the documentation actually describes removal of only part of an organ, or vice versa when a whole lobe or the entire gallbladder was removed.
