Biopsy, breast, with placement of breast localization device(s) (eg, clip, metallic pellet), when performed, and imaging of the biopsy specimen, when performed, percutaneous; first lesion, including stereotactic guidance

Common Language Description

A percutaneous breast biopsy is a minimally invasive procedure that allows for the sampling of breast tissue to diagnose potential abnormalities. This procedure is guided by stereotactic imaging, which employs a fixed coordinate system to accurately locate the lesion within the breast. The process begins with the cleansing of the skin and the administration of a local anesthetic to ensure patient comfort. Stereotactic guidance involves the use of imaging technology to pinpoint the lesion's precise location by defining it in three-dimensional coordinates relative to a reference point. During the procedure, the breast is positioned between a compression plate and a support structure, which stabilizes the lesion for accurate targeting. The thickness of the breast under compression is a critical factor in determining the depth of the lesion. An initial imaging study is performed at a perpendicular angle to the compression plate, which helps to center the lesion within the biopsy window. Subsequent images are taken at various angles to further refine the location of the lesion through geometric calculations. If a needle biopsy is indicated, a needle is carefully inserted into the lesion to obtain a tissue sample. Typically, multiple core needle insertions—ranging from three to six—are necessary to ensure that an adequate sample is collected for analysis. Once the tissue sample is secured, it is sent to a laboratory for pathological examination. In cases where an automated vacuum-assisted or rotating biopsy device is utilized, the procedure involves making a small incision in the skin and placing a breast probe at the lesion site. The device then uses suction to draw tissue into its sampling chamber, or a rotating cutting mechanism is employed to capture tissue samples. This process may involve taking between eight to ten samples, with the probe being repositioned at approximately 30-degree intervals. After the sampling is completed, pressure is applied to the biopsy site to minimize bleeding. Additionally, a metallic localization clip or pellet may be placed at the biopsy site to assist in future surgical procedures, such as a lumpectomy, by marking the exact location of the tissue removal. The procedure concludes with the removal of the biopsy needle and the potential acquisition of additional images of the biopsy specimen for further evaluation.

1. Indications

The percutaneous breast biopsy procedure is indicated for the evaluation of various breast abnormalities. These may include:

  • Suspicious Lesions: Lesions that appear abnormal on imaging studies, such as mammograms or ultrasounds, warrant further investigation to determine if they are benign or malignant.
  • Palpable Masses: Any palpable breast masses that require histological examination to assess their nature and guide treatment decisions.
  • Microcalcifications: Areas of microcalcifications identified on mammography that may indicate underlying pathology necessitating biopsy for diagnosis.
  • Follow-Up of Previous Findings: Patients with a history of breast abnormalities or previous biopsies may require additional sampling to monitor changes over time.

2. Procedure

The procedure for a percutaneous breast biopsy with stereotactic guidance involves several critical steps to ensure accurate tissue sampling. First, the patient is positioned appropriately, and the breast is placed between a compression plate and a support structure to stabilize the area of interest. The skin over the biopsy site is then cleansed with an antiseptic solution, and a local anesthetic is injected to minimize discomfort during the procedure. Following this, stereotactic imaging is utilized to obtain an initial image of the breast at a perpendicular angle to the compression plate. This image serves as a reference point to center the lesion within the biopsy window. Subsequent images are captured at various angles, allowing for precise geometric calculations to determine the lesion's three-dimensional coordinates. Once the lesion is accurately located, a biopsy needle is inserted into the lesion to collect tissue samples. Typically, three to six core needle insertions are performed to ensure that sufficient tissue is obtained for pathological analysis. If an automated vacuum-assisted or rotating biopsy device is employed, a small incision is made, and a breast probe is inserted at the lesion site. The device uses suction to draw tissue into its sampling chamber, or a rotating cutting mechanism is utilized to capture tissue samples. This process may involve taking eight to ten samples, with the probe being repositioned at approximately 30-degree intervals to ensure comprehensive sampling. After the tissue samples are collected, they are sent to a laboratory for pathological examination. If a localization clip or pellet is indicated, the biopsy needle is left in place, and a plastic stylet with the clip or pellet is inserted through the needle and advanced to the biopsy site using imaging guidance. The clip or pellet is then released, and both the stylet and needle are removed. Finally, additional images of the biopsy specimen may be obtained to assist in the evaluation prior to the separate reportable pathology examination.

3. Post-Procedure

After the completion of the percutaneous breast biopsy, the patient is monitored for any immediate complications, such as bleeding or discomfort at the biopsy site. Pressure is applied to the area to minimize bleeding, and the patient may be advised to avoid strenuous activities for a short period. Instructions regarding care of the biopsy site, including keeping it clean and dry, are provided. Patients are typically informed about potential side effects, such as bruising or swelling, which may occur but usually resolve within a few days. Follow-up appointments may be scheduled to discuss the results of the pathological examination and to determine any further necessary actions based on the findings.

76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.
