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

Hepatic Duct, Right

The right hepatic duct collects bile from the right lobe of the liver before joining its left-sided counterpart to form the common hepatic duct. Excision of this structure involves cutting out a portion of the duct, typically to remove a stricture, tumor such as cholangiocarcinoma, or damaged segment following injury, without necessarily removing the entire biliary tree on that side. Because the right hepatic duct is short and located deep within the porta hepatis near major vascular structures, resection here often requires biliary reconstruction, such as a hepaticojejunostomy, to restore drainage afterward, and that reconstructive step is coded separately from the excision itself. The operative note should specify right-sided laterality clearly, since left, right, and common hepatic duct excisions are each assigned distinct codes.

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.

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.

Commonly Confused With

ResectionExcision is easily confused with Resection, which applies when an entire body part (e.g., the whole gallbladder or whole pancreas) is removed rather than a portion.
ExtirpationIt's also confused with Extirpation, which is reserved for removing abnormal solid matter such as a stone or foreign body rather than normal or diseased tissue that is part of the body part itself.
DrainageDrainage procedures that remove fluid, not solid tissue, belong to a separate root operation entirely.
