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
Hepatic Duct, Left
The left hepatic duct drains bile from the left lobe of the liver and merges with the right hepatic duct to form the common hepatic duct at the porta hepatis. Excision of this duct removes a segment affected by stricture, tumor, or traumatic injury, and is distinguished from procedures on the right or common duct by its specific anatomic origin from left-sided liver segments. The left duct's extrahepatic course is often slightly longer and more variable than the right, which can influence surgical exposure and the technique used for any subsequent reconstruction. As with other segmental biliary excisions, the operative documentation needs to establish that the tissue removed was specifically from the left hepatic duct rather than a more distal or proximal portion of the biliary tree.
Approach: Via Natural or Artificial Opening Endoscopic
Via Natural or Artificial Opening Endoscopic describes instrumentation introduced through a natural orifice or a surgically created opening while using an endoscope for visualization, as in a routine colonoscopy performed through the anus. It differs from the plain Via Natural or Artificial Opening value by the added scope, and from Percutaneous Endoscopic by using an existing passage rather than a new skin puncture.
Qualifier: Diagnostic
Applied chiefly to Excision, this qualifier marks that tissue was removed specifically for diagnostic purposes, i.e., a biopsy intended for pathologic evaluation rather than to treat disease. It distinguishes biopsy-type excisions from therapeutic excisions of the same body part, which are coded without this qualifier even though the physical technique may be identical.
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.
