Official Description

Hepatotomy, for open drainage of abscess or cyst, 1 or 2 stages

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 47010 refers to a surgical procedure known as hepatotomy, which is performed for the open drainage of an abscess or cyst located in the liver. This procedure can be executed in one or two stages, depending on the clinical situation. In a typical hepatotomy, a surgical incision is made to access the liver, allowing the surgeon to visualize the affected area. The most common approach involves a right subcostal incision, which may extend towards the xiphoid process or into the left subcostal region. This incision facilitates the transection of the right rectus muscle and the splitting of the oblique muscles, providing access to the liver. Once the liver is exposed, the surgeon locates the abscess or cyst, incises it, and drains its contents. Additionally, the abdomen is explored for any signs of peritonitis or other potential abscess sites. If the procedure is performed as a one-stage operation, a drain is placed within the abscess or cyst to facilitate further drainage, and the abdomen is subsequently closed around the drain. In cases where a two-stage procedure is necessary, the initial wound is left open to allow for continuous drainage, with closure occurring in a later surgical session once the infection has resolved. Although less common, a transpleural approach may be utilized if the abscess or cyst is situated in the upper posterior aspect of the liver; however, this method limits the ability to explore the abdomen thoroughly.

1. Indications

The procedure described by CPT® Code 47010 is indicated for the management of liver abscesses or cysts that require surgical intervention for drainage. The following conditions may warrant the performance of a hepatotomy:

  • Liver Abscess - A localized collection of pus within the liver, often resulting from infection, which may require drainage to alleviate symptoms and prevent complications.
  • Liver Cyst - A fluid-filled sac within the liver that may become symptomatic or infected, necessitating surgical drainage to relieve discomfort or prevent further complications.
  • Signs of Peritonitis - Evidence of inflammation of the peritoneum, which may be associated with an abscess or cyst, indicating the need for surgical intervention to explore and address the underlying issue.

2. Procedure

The hepatotomy procedure involves several critical steps to ensure effective drainage of the abscess or cyst. The following outlines the procedural steps as described:

  • Step 1: Incision - The procedure typically begins with a right subcostal incision, which may extend towards the xiphoid process or into the left subcostal region. This incision allows for adequate access to the liver and surrounding structures.
  • Step 2: Muscle Transection and Splitting - Following the incision, the right rectus muscle is transected, and the oblique muscles are split to facilitate visualization of the liver. This step is crucial for gaining access to the hepatic tissue where the abscess or cyst is located.
  • Step 3: Visualization and Drainage - Once the liver is adequately exposed, the surgeon locates the abscess or cyst. The lesion is then incised, and its contents are drained to relieve pressure and prevent further complications.
  • Step 4: Abdominal Exploration - After draining the abscess or cyst, the abdomen is explored for any signs of peritonitis or additional abscess sites. This exploration is essential to ensure that no other complications are present that require attention.
  • Step 5: Drain Placement (One-Stage Procedure) - If the procedure is performed as a one-stage operation, a drain is placed within the abscess or cyst to facilitate ongoing drainage. The abdomen is then closed around the drain to allow for continued monitoring and management.
  • Step 6: Wound Management (Two-Stage Procedure) - In cases where a two-stage procedure is necessary, the initial wound is left open to allow for continuous drainage. The closure of the wound occurs during a subsequent surgical session after the infection has resolved, ensuring that the area is adequately healed.
  • Step 7: Alternative Approach - If the abscess or cyst is located in the upper posterior aspect of the liver, a transpleural approach may be utilized. However, this approach is less common due to its limitations in allowing for thorough abdominal exploration.

3. Post-Procedure

Post-procedure care following a hepatotomy involves monitoring the patient for signs of infection, ensuring proper drainage from the placed drain, and managing any discomfort. If a one-stage procedure was performed, the drain will need to be monitored for output and may require care to prevent blockage or infection. In the case of a two-stage procedure, the patient will need to be evaluated during the healing process, and a follow-up surgical session will be scheduled to close the wound once the infection has resolved. Additionally, the patient may require supportive care, including pain management and nutritional support, as they recover from the surgery.

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).
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).
