Official Description

Biopsy of breast; open, incisional

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 19101 refers to an open incisional biopsy of the breast. In this surgical intervention, a physician makes a deliberate incision in the skin above a suspicious mass located in the breast tissue. The primary objective of this procedure is to obtain a sample of the tissue from the identified mass for pathological examination. This examination is crucial as it helps determine the nature of the mass—whether it is benign (non-cancerous) or malignant (cancerous). Following the removal of the tissue sample, the physician assesses the findings. If the results indicate that the mass is benign, the incision is typically closed using layered sutures to promote proper healing. Conversely, if the biopsy reveals malignancy, the wound may be temporarily closed, allowing for further evaluation and planning for more extensive surgical intervention if necessary. This procedure is an essential diagnostic tool in breast health management, aiding in the early detection and treatment of breast conditions.

1. Indications

The open incisional biopsy of the breast, as described by CPT® Code 19101, is indicated for various clinical scenarios where there is a suspicion of abnormal tissue. The following conditions may warrant this procedure:

  • Suspicious Breast Mass The presence of a palpable lump or mass in the breast that raises concern for potential malignancy.
  • Abnormal Imaging Findings Results from mammograms or ultrasound studies that suggest the presence of a suspicious lesion requiring further investigation.
  • Persistent Symptoms Ongoing breast pain, changes in breast shape, or other symptoms that do not resolve and necessitate further evaluation.

2. Procedure

The procedure for an open incisional biopsy of the breast involves several critical steps to ensure accurate tissue sampling and patient safety. The following outlines the procedural steps:

  • Step 1: Patient Preparation The patient is positioned comfortably, and the area around the breast is cleaned and sterilized to minimize the risk of infection. Local anesthesia is administered to numb the area, ensuring the patient experiences minimal discomfort during the procedure.
  • Step 2: Incision Creation The physician makes a precise incision in the skin above the suspicious mass. The size and location of the incision are determined based on the mass's position and size, allowing for optimal access to the tissue.
  • Step 3: Tissue Sampling Once the incision is made, the physician carefully dissects through the breast tissue to reach the suspicious mass. A sample of the tissue is excised using surgical instruments, ensuring that an adequate amount is collected for pathological analysis.
  • Step 4: Wound Closure After the tissue sample is obtained, the physician evaluates the mass. If the biopsy results indicate that the mass is benign, the incision is closed using layered sutures to promote healing. If the mass is found to be malignant, the wound may be temporarily closed, allowing for further surgical planning.

3. Post-Procedure

Post-procedure care following an open incisional biopsy of the breast is essential for recovery and monitoring. Patients are typically advised to rest and avoid strenuous activities for a specified period. The incision site should be kept clean and dry, and any dressings should be changed as instructed by the healthcare provider. Patients may experience some discomfort, swelling, or bruising at the site, which can be managed with prescribed pain relief medications. Follow-up appointments are crucial to discuss biopsy results and determine any further treatment if necessary. Additionally, patients should be educated on signs of infection or complications, such as increased redness, swelling, or discharge from the incision site, and advised to seek medical attention if these occur.

50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
CR Catastrophe/disaster related
GA Waiver of liability statement issued as required by payer policy, individual case
GC This service has been performed in part by a resident under the direction of a teaching physician
GV Attending physician not employed or paid under arrangement by the patient's hospice provider
GW Service not related to the hospice patient's terminal condition
LT Left side (used to identify procedures performed on the left side of the body)
RT Right side (used to identify procedures performed on the right side of the body)
SG Ambulatory surgical center (asc) facility service
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
