47562

Laparoscopic Cholecystectomy

Laparoscopic cholecystectomy (CPT code 47562) is a minimally invasive surgical procedure for the removal of the gallbladder. This procedure is performed through several small abdominal incisions (typically 3-4), through which a laparoscope (a thin, lighted tube with a camera) and specialized surgical instruments are inserted. The surgeon visualizes the abdominal cavity on a monitor and uses the instruments to carefully dissect the gallbladder from its attachments to the liver, clip and divide the cystic duct and cystic artery, and then remove the gallbladder through one of the small incisions. This technique is favored for its benefits, including reduced postoperative pain, shorter hospital stays, and quicker recovery times compared to traditional open cholecystectomy.

Clinical Indications

  • Symptomatic cholelithiasis (gallstones causing biliary colic, nausea, vomiting, or dyspepsia)
  • Acute cholecystitis (inflammation of the gallbladder, often due to gallstone obstruction)
  • Chronic cholecystitis (persistent inflammation of the gallbladder, usually associated with gallstones)
  • Biliary dyskinesia (functional disorder of the gallbladder characterized by abdominal pain and an abnormal gallbladder ejection fraction on HIDA scan, typically <35-40%)
  • Gallbladder polyps (especially those greater than 1 cm in size, rapidly growing, or symptomatic)
  • Acalculous cholecystitis (inflammation of the gallbladder in the absence of gallstones)
  • Pancreatitis caused by gallstones (to prevent recurrent episodes)

Procedure Steps

  1. Patient is placed in the supine position, and general anesthesia is administered.
  2. A small incision is made, typically at the umbilicus, for initial access.
  3. Pneumoperitoneum is created by insufflating carbon dioxide into the abdominal cavity to create working space.
  4. A trocar is inserted through the initial incision, and the laparoscope is introduced to visualize the abdominal contents.
  5. Additional trocars (usually 2-3) are placed in other abdominal quadrants under direct vision.
  6. The gallbladder is identified and grasped, then retracted to expose Calot's triangle.
  7. Careful dissection is performed to identify and isolate the cystic duct and cystic artery.
  8. The cystic duct and cystic artery are individually clipped and then divided.
  9. The gallbladder is meticulously dissected from the liver bed using electrocautery or other energy devices.
  10. The detached gallbladder is placed into an endoscopic retrieval bag and removed from the abdominal cavity through one of the trocar sites.
  11. The surgical field is inspected for hemostasis and bile leakage.
  12. Carbon dioxide is desufflated, trocars are removed, and incisions are closed with sutures or staples.

Coding Guidelines

  • Code 47562 includes the standard laparoscopic approach for the complete removal of the gallbladder.
  • If intraoperative cholangiography is performed, use CPT code 47563 (Laparoscopy, surgical; cholecystectomy with cholangiography) instead of 47562. Do not report 47562 and 47563 together.
  • If the laparoscopic procedure is converted to an open cholecystectomy (e.g., due to complications or difficult anatomy), report only the appropriate open cholecystectomy code (e.g., 47600) and append modifier 22 (Increased Procedural Services) to indicate the additional work, with thorough documentation of the conversion reason.
  • Do not report 47562 in conjunction with open cholecystectomy codes (47600-47630) for the same surgical session.
  • This procedure has a 90-day global surgical period, meaning routine pre-operative, intra-operative, and post-operative care within this timeframe is included in the reimbursement.
  • Comprehensive documentation in the operative report is essential, detailing the surgical approach, identification of structures, dissection, ligation, and removal of the gallbladder, and any findings or complications.
