DEFINITION of cholecystectomy

cholecystectomy is the surgical excision of the gallbladder, performed either through a minimally invasive laparoscopic approach or a traditional open abdominal incision. It is distinguished from cholecystostomy, which drains rather than removes the gallbladder, and from choledochotomy, which incises the common bile duct rather than excising the organ itself. The underlying mechanism is mechanical: the surgeon dissects the gallbladder free from its bed on the liver and ligates and divides the cystic artery and cystic duct before removing the organ. cholecystectomy is almost always pathological in intent — performed for symptomatic cholelithiasis, acute or chronic cholecystitis, biliary dyskinesia, or gallbladder polyps/malignancy — rather than prophylactic, though it is occasionally performed incidentally during another abdominal operation. The two clinically and procedurally distinct forms most relevant to coding are the laparoscopic approach (reported with 47562–47564) and the open approach (reported with 47600–47612). It is commonly confused with cholecystotomy, which opens the gallbladder to remove stones while leaving the organ in place, and with cholangiectomy, a much rarer excision of a bile duct segment rather than the gallbladder itself.


ETYMOLOGY of cholecystectomy

greek

ComponentOriginMeaning
chole-Greek χολή (kholḗ)“bile,” “gall” — combining form denoting the biliary system
cyst-Greek κύστις (kýstis), “bladder, pouch, sac""bladder,” “sac,” “pouch” — here referring specifically to the gallbladder as a bile-storing sac
-ectomyGreek ἐκτομή (ektomḗ), from ek- (“out”) + tomḗ (“a cutting”)Noun-forming surgical suffix — “excision of,” “a cutting out”

The word entered English medical usage in the 1880s as cholecystectomy (noun), coined directly from the Greek combining forms chole- + cyst- + -ectomy to name the new operation first performed by German surgeon Carl Langenbuch in 1882. The root chole- (“bile”) connects cholecystectomy to the entire -chole family: cholecystitis (chole- + cyst- + -itis → “inflammation of the gallbladder”), cholelithiasis (chole- + lith- + -iasis → “condition of gallstones”), and cholangitis (chol- + ang- + -itis → “inflammation of a bile duct”). The suffix -ectomy is highly productive in surgical terminology, appearing in appendectomy, tonsillectomy, nephrectomy, and splenectomy.

  • Single-incision laparoscopic cholecystectomy (SILC) (technique variant using one umbilical port rather than multiple standard ports; still reported under the standard laparoscopic CPT family)
  • Robotic-assisted cholecystectomy (technique variant performed with robotic surgical platform assistance; coded under the same laparoscopic CPT family per current CPT guidance)
  • Cholecystectomy with cholangiography (procedural subtype including intraoperative bile duct imaging; 47563 laparoscopic or 47605 open)

🔗 RELATED TERMS

  • Cholecystostomy — the opposite intent from cholecystectomy; a drainage procedure that places a tube into the gallbladder without removing it, typically as a temporizing measure in a critically ill patient too unstable for surgery.
  • Cholecystotomy — shares the cyst- root; an incision into the gallbladder to remove stones while leaving the organ itself in place.
  • cholecystitis — inflammation of the gallbladder, the most common indication for cholecystectomy; billable codes include K81.0 (acute), K81.1 (chronic), K81.2 (acute and chronic), and K81.9 (unspecified).
  • Cholelithiasis — presence of gallstones within the gallbladder or biliary tract; frequently coexists with cholecystitis and is the leading indication for cholecystectomy, with numerous combination codes such as K80.00 and K80.01.
  • Choledocholithiasis — presence of stones within the common bile duct rather than the gallbladder; may require concurrent common bile duct exploration during cholecystectomy.
  • Biliary colic — the mechanism-related symptom pattern of intermittent right-upper-quadrant pain caused by transient cystic duct obstruction from a stone, often the presenting complaint that leads to elective cholecystectomy.
  • Cholestasis — adjective-related disruption of bile flow; a contributing physiological mechanism in several gallbladder and biliary conditions requiring surgical intervention.
  • Cholangitis — inflammation of the bile ducts, a serious complication that can accompany choledocholithiasis and may prompt urgent biliary decompression before or instead of cholecystectomy.
  • Gangrenous cholecystitis — a severe, tissue-necrosing complication of acute cholecystitis; coded with K82.A1 (use additional code alongside the underlying cholecystitis code).
  • Gallbladder perforation — a life-threatening complication of untreated or gangrenous cholecystitis; coded with K82.A2 (use additional code alongside the underlying cholecystitis code).
  • Intraoperative cholangiogram (IOC) — the primary diagnostic tool used during cholecystectomy to visualize the biliary tree and detect retained common bile duct stones.

⚠️ Coding Note: The K80/K81/K82 code families require full specificity to the character level supported by documentation — most notably obstruction status (“with obstruction” vs. “without obstruction”) on the calculus-with-cholecystitis codes, which is frequently left unqueried on inpatient profee charts. Sequence the underlying gallbladder condition (e.g., K80.01, K81.0) as principal diagnosis when it is the reason for admission and the cholecystectomy is performed to treat it; report K82.A1/K82.A2 only as an additional code alongside the cholecystitis code, never as a stand-alone principal diagnosis, per the “use additional code” instructional note. A frequently undercoded finding is gangrenous or perforated cholecystitis: watch operative-note language such as “necrotic,” “friable,” “gangrenous,” or “frank perforation with bile leak,” which should trigger a query for K82.A1/K82.A2 if not already captured. Never report a laparoscopic CPT code (47562–47564) together with an open code on the same claim — if the case converts to open, only the open code is reportable, per current NCCI Policy Manual guidance. ICG (indocyanine green) fluorescence imaging alone does not qualify as cholangiography for CPT purposes; only fluoroscopic contrast injection supports 47563/47605.
