Official Description

Placement of breast localization device(s) (eg, clip, metallic pellet, wire/needle, radioactive seeds), percutaneous; first lesion, including ultrasound guidance

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 19285 involves the placement of a breast localization device, which is essential for accurately identifying the location of a lesion prior to performing a breast biopsy or lumpectomy. This localization is crucial for ensuring that the surgeon targets the correct area during the surgical procedure. The devices used for localization can include clips, metallic pellets, wires or needles, and radioactive seeds. The process begins with the marking of the area of concern on the skin, followed by the acquisition of ultrasound images of the breast to visualize the lesion. A transducer is employed to precisely locate the lesion, and the physician uses these images to guide the insertion of a needle into the lesion. Throughout this process, the radiologist continuously monitors the placement of the needle to confirm that it is correctly positioned within the mass. For wire localization, a hooked wire is inserted at a perpendicular angle to the lesion using a needle, ensuring that the wire remains anchored within the mass once the needle is withdrawn, with a portion of the wire extending outside the skin. Alternatively, a plastic stylet equipped with a localization device, such as a clip, metallic pellet, or radioactive seed, is inserted through the biopsy needle and advanced to the lesion site under ultrasound guidance. Once the localization device is in place, it is released, and both the stylet and needle are removed. This procedure is specifically coded as 19285 for the first lesion, while 19286 is used for each additional lesion that may require localization.

1. Indications

The placement of a breast localization device is indicated for the following conditions:

  • Lesion Identification The procedure is performed to accurately identify the location of a breast lesion prior to a biopsy or lumpectomy.
  • Pre-Surgical Planning It is utilized to facilitate surgical planning by marking the precise site of the lesion for the surgeon.
  • Guidance for Biopsy The localization device aids in guiding the biopsy needle to ensure that the tissue sample is taken from the correct area of concern.

2. Procedure

The procedure for the placement of a breast localization device involves several key steps that ensure accurate localization of the lesion. First, the physician marks the area of concern on the skin, which serves as a reference point for the procedure. Next, ultrasound images of the breast are obtained using a transducer, which allows the physician to visualize the lesion in real-time. This imaging is critical for guiding the placement of the localization device. Once the lesion is located, the physician advances a needle into the lesion while continuously monitoring the ultrasound images to confirm the needle's placement within the mass. For wire localization, a hooked wire is inserted into the lesion at a perpendicular angle through the needle. After the wire is positioned correctly, the needle is withdrawn, leaving the wire anchored within the mass, with a short length extending out through the skin. Alternatively, if a localization device such as a clip, metallic pellet, or radioactive seed is used, a plastic stylet is inserted through the biopsy needle and advanced to the lesion site under ultrasound guidance. Once the localization device reaches the intended location, it is released, and both the stylet and needle are removed, completing the procedure.

3. Post-Procedure

After the placement of the breast localization device, patients may be monitored for any immediate complications, although significant post-procedure care is typically minimal. Patients are advised to follow any specific instructions provided by their healthcare provider, which may include monitoring the insertion site for signs of infection or unusual swelling. The localization device remains in place until the surgical procedure, such as a biopsy or lumpectomy, is performed. It is important for patients to keep the area clean and to report any concerns to their healthcare provider. Follow-up appointments may be scheduled to ensure proper healing and to discuss the results of the subsequent surgical procedure.
