Official Description

Biopsy of liver, needle; when done for indicated purpose at time of other major procedure (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 47001 refers to a biopsy of the liver performed using a needle technique. This procedure is specifically indicated when it is conducted for an appropriate medical purpose concurrently with another major surgical procedure. Prior to the biopsy, the skin over the liver area is thoroughly cleansed to minimize the risk of infection, and a local anesthetic is administered to ensure patient comfort during the procedure. The biopsy involves the use of a percutaneous needle technique, which means that the needle is inserted through the skin directly into the liver to obtain a tissue sample. To enhance the accuracy of the biopsy, imaging guidance may be employed, which can include ultrasound, fluoroscopy, computed tomography (CT), or magnetic resonance imaging (MRI). These imaging techniques assist in precisely locating the abnormal tissue within the liver that requires sampling. It is important to note that this procedure is reported separately from the primary procedure being performed, particularly when it is done through an existing abdominal incision during that primary procedure. The use of a large-bore needle or a spring-loaded biopsy gun is common in this context to facilitate the withdrawal of the liver tissue sample effectively.

1. Indications

The biopsy of the liver using a needle, as described by CPT® Code 47001, is indicated for various clinical scenarios where a tissue sample is necessary for diagnostic purposes. The following conditions may warrant this procedure:

  • Suspicion of Liver Disease - When there is a clinical suspicion of liver disease, such as hepatitis, cirrhosis, or liver tumors, a biopsy may be performed to obtain tissue for histological examination.
  • Evaluation of Abnormal Liver Function Tests - If a patient presents with abnormal liver function tests, a biopsy can help determine the underlying cause of the dysfunction.
  • Assessment of Liver Lesions - In cases where imaging studies reveal liver lesions, a biopsy may be necessary to ascertain whether these lesions are benign or malignant.

2. Procedure

The procedure for a liver biopsy using CPT® Code 47001 involves several critical steps to ensure the safe and effective collection of liver tissue. The following procedural steps are typically followed:

  • Preparation - The patient is positioned appropriately, and the skin over the liver is cleansed with an antiseptic solution to reduce the risk of infection. A local anesthetic is then injected to numb the area where the needle will be inserted, ensuring the patient experiences minimal discomfort during the procedure.
  • Imaging Guidance - If necessary, imaging guidance such as ultrasound, fluoroscopy, CT, or MRI is utilized to accurately locate the area of the liver that requires biopsy. This step is crucial for targeting the abnormal tissue effectively.
  • Needle Insertion - A large-bore needle or a spring-loaded biopsy gun is carefully inserted through the skin and into the liver. The physician may use real-time imaging to guide the needle to the precise location of the abnormal tissue.
  • Tissue Sample Collection - Once the needle is in position, a tissue sample is withdrawn from the liver. The sample size is typically sufficient for histological analysis, which will be performed by a pathologist to determine the nature of the liver condition.
  • Post-Procedure Care - After the biopsy, the needle is removed, and pressure is applied to the site to minimize bleeding. The patient is monitored for any immediate complications before being discharged.

3. Post-Procedure

Following the liver biopsy procedure, patients are typically monitored for a short period to ensure there are no immediate complications, such as bleeding or infection. It is common for patients to experience some discomfort or soreness at the biopsy site, which can usually be managed with over-the-counter pain relief. Patients may be advised to avoid strenuous activities for a short period following the procedure to allow for proper healing. Additionally, follow-up appointments may be scheduled to discuss the biopsy results and any further management based on the findings.

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.
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).
