CPT 47480 Gallbladder Incision Reimbursement | OpenPayer

Summary & Overview

CPT 47480: Gallbladder Incision for Stone Removal or Drainage

CPT code 47480 designates an incision of the gallbladder to inspect its interior, remove stones, or perform drainage. It represents a focused surgical intervention used when endoscopic or laparoscopic approaches are unsuitable or when direct access to the gallbladder lumen is required. Nationally, this procedure is relevant for acute biliary presentations where stone extraction or drainage cannot be achieved noninvasively and where surgical exploration is indicated.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines how CPT code 47480 is billed across surgical service lines, typical sites of service, and the clinical contexts that commonly prompt use of the code. Readers will find benchmarks for utilization and payment patterns, summaries of relevant billing policy considerations, and clinical context describing when an incision and exploration of the gallbladder is performed versus alternative biliary procedures.

The report provides a concise reference for coding, claims review, and policy teams seeking to understand where 47480 fits within gallbladder and biliary service lines, and what to expect in terms of payer coverage frameworks and clinical justification for the procedure.

Billing Code Overview

CPT code 47480 describes a procedure in which the provider identifies and incises the gallbladder to directly examine its lumen, remove a stone, or provide drainage. This procedure is a surgical gallbladder incision typically performed to relieve obstruction, extract impacted stones, or drain infected or retained bile.

Service Type: Surgical procedural service (open or incision-based gallbladder procedure)

Typical Site of Service: Operating room or procedural suite, often in an inpatient or ambulatory surgical setting

Clinical & Coding Specifications

Clinical Context

A 52-year-old patient presents to the hospital emergency department with right upper quadrant abdominal pain, fever, and jaundice consistent with acute cholecystitis complicated by an impacted gallstone and localized empyema of the gallbladder. Initial evaluation includes history, physical exam, laboratory studies (CBC, CMP, liver function tests), and imaging with abdominal ultrasound or CT showing a distended gallbladder with an obstructing stone. The surgical team obtains informed consent for an open or laparoscopic operative approach. Intraoperatively the surgeon identifies and incises the gallbladder to examine the lumen, evacuate pus and bile, and remove impacted stone fragments; irrigation and drainage are performed and a drain may be left in place. Typical workflow: preoperative anesthesia evaluation, operative incision and exposure of the gallbladder, intraoperative cholangiography if indicated, incision of the gallbladder (CPT 47480), stone extraction or drainage, hemostasis and closure, postoperative monitoring in recovery or inpatient unit, and discharge planning with antibiotics and follow-up for potential definitive cholecystectomy if only drainage was performed.

ICD-10 Code	Description	Clinical Relevance
`K80.00`	Calculus of gallbladder with acute cholecystitis without obstruction	Common indication when an impacted gallstone causes acute inflammation and incision/drainage is needed.
`K80.10`	Calculus of gallbladder with other cholecystitis without obstruction	Indicates gallstone-related inflammation where gallbladder exploration or stone removal may be performed.
`K80.20`	Calculus of gallbladder without cholecystitis	May be relevant when stones are incidentally found and removed during exploration.
`K81.0`	Acute cholecystitis	Primary diagnosis prompting incision and drainage for infected or perforated gallbladder.
`K83.1`	Obstruction of bile duct	Relevant when stones or sludge obstruct biliary flow, requiring exploration and stone extraction.
