Official Description

Laparoscopy, surgical; cholecystectomy with exploration of common duct

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 47564 involves a laparoscopic cholecystectomy, which is a minimally invasive surgical technique used to remove the gallbladder. This procedure is performed through small incisions in the abdomen, allowing for reduced recovery time and less postoperative pain compared to traditional open surgery. During the operation, the surgeon not only removes the gallbladder but also explores the common bile duct to ensure that no stones are present, which could lead to complications. The process begins with the creation of a small incision at the navel, through which a trocar is inserted to allow access for a laparoscope—a thin tube equipped with a camera that provides visualization of the internal structures. The abdomen is inflated with carbon dioxide to create a working space for the surgeon. Additional incisions are made to insert other surgical instruments necessary for the procedure. The gallbladder is carefully identified and, if necessary, drained of bile to facilitate its removal. Key anatomical structures, such as the cystic artery and cystic duct, are meticulously dissected and ligated to prevent bleeding. The exploration of the common bile duct is critical, as it allows for the identification and removal of any gallstones that may have migrated into the duct. After ensuring the area is clear of stones, the gallbladder is detached from the liver and removed through one of the small incisions. This comprehensive approach not only addresses the gallbladder issue but also safeguards against potential complications related to the biliary system.

1. Indications

The laparoscopic cholecystectomy with exploration of the common duct, as described by CPT® Code 47564, is indicated for several conditions related to the gallbladder and biliary system. These include:

  • Cholelithiasis The presence of gallstones in the gallbladder, which can cause pain, inflammation, or infection.
  • Cholecystitis Inflammation of the gallbladder, often due to obstruction by gallstones, leading to severe abdominal pain and potential complications.
  • Choledocholithiasis The presence of gallstones in the common bile duct, which can obstruct bile flow and lead to jaundice or pancreatitis.
  • Biliary colic Episodes of severe pain caused by gallstones temporarily blocking the bile duct.

2. Procedure

The laparoscopic cholecystectomy with exploration of the common duct involves several key procedural steps:

  • Step 1: The procedure begins with the patient being placed under general anesthesia. A small incision is made at the navel, and a trocar is inserted to allow access for the laparoscope.
  • Step 2: Carbon dioxide is introduced into the abdominal cavity to inflate it, creating a working space for the surgeon to operate.
  • Step 3: Two to three additional incisions are made in the abdomen, and trocars are inserted to facilitate the placement of surgical instruments needed for the procedure.
  • Step 4: The gallbladder is identified, and if it is distended, a needle may be used to drain bile from it to reduce its size and facilitate removal.
  • Step 5: Grasper clamps are applied to hold the gallbladder in place. The Hartmann's pouch is identified and retracted to expose the triangle of Calot, where the cystic artery and cystic duct are located.
  • Step 6: The cystic duct is carefully dissected free from surrounding tissues and then transected to allow for the removal of the gallbladder.
  • Step 7: The common bile duct is explored by making a small incision in its anterior superior aspect. A catheter is advanced into the duct for visualization.
  • Step 8: If any calculi (gallstones) are found during the exploration, a basket extraction catheter is utilized to remove them from the common bile duct.
  • Step 9: Once all stones are removed, the biliary tract is flushed and filled with saline to ensure it is clear.
  • Step 10: A drainage catheter may be placed if necessary to facilitate postoperative drainage.
  • Step 11: Following the exploration of the common duct, the cystic artery is dissected free, ligated, and doubly divided to prevent bleeding.
  • Step 12: Electrocautery is then used to carefully dissect the gallbladder off the liver bed.
  • Step 13: Finally, the gallbladder is placed in an extraction sac and removed from the abdomen through one of the small incisions.

3. Post-Procedure

After the laparoscopic cholecystectomy with exploration of the common duct, patients can expect a recovery period that typically involves monitoring for any complications such as bleeding or infection. Postoperative care may include pain management, instructions for activity restrictions, and dietary modifications as the patient adjusts to the absence of the gallbladder. Follow-up appointments may be scheduled to ensure proper healing and to address any concerns that may arise during the recovery process. Patients are generally encouraged to resume normal activities within a few weeks, depending on their individual recovery progress.

AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
GC This service has been performed in part by a resident under the direction of a teaching physician
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
