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

Pancreatic Duct, Accessory

The accessory pancreatic duct, or duct of Santorini, drains portions of the pancreatic head through the minor duodenal papilla and can serve as the dominant outflow route in individuals with pancreas divisum. Excision of tissue from this duct is uncommon and generally reserved for focal lesions, such as small neoplasms or damaged segments identified along this specific channel, distinct from procedures on the main pancreatic duct. Because the accessory duct is narrower and more variable in its course and connections, precise identification during surgery or endoscopy is important before any tissue is removed. Documentation should confirm that the excised tissue came from the accessory duct rather than the main pancreatic duct, since the two structures are coded under separate body part values despite their anatomic proximity.

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.

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.
