Official Description

Placement of soft tissue localization device(s) (eg, clip, metallic pellet, wire/needle, radioactive seeds), percutaneous, including imaging guidance; each additional lesion (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 10036 refers to the procedure involving the placement of soft tissue localization device(s) such as clips, metallic pellets, wires/needles, or radioactive seeds. This procedure is performed percutaneously, meaning it is done through the skin, and includes the use of imaging guidance to ensure accurate placement of the localization device. The primary purpose of this procedure is to mark the exact site of a lesion, which is crucial for subsequent interventions like biopsies or en bloc removals. By utilizing imaging techniques, the physician can visualize the target tissue and confirm the precise location of the lesion. The localization devices serve as markers that help guide the surgeon during the procedure, ensuring that the correct area is addressed. It is important to note that this code is specifically for each additional lesion, and it should be billed separately in conjunction with the primary procedure code, which is CPT® Code 10035 for the first lesion. This structured approach enhances the accuracy of surgical interventions and improves patient outcomes by facilitating targeted treatment of lesions.

1. Indications

The placement of soft tissue localization device(s) is indicated for various clinical scenarios where precise identification of a lesion is necessary prior to surgical intervention. The following conditions may warrant this procedure:

  • Lesion Identification: When a lesion is detected that requires biopsy or surgical removal, localization devices help in accurately targeting the area.
  • Imaging Guidance: The procedure is indicated when imaging studies (such as mammography or ultrasound) reveal lesions that are not easily palpable or visible during surgery.
  • Multiple Lesions: In cases where multiple lesions are present, the use of localization devices for each additional lesion is necessary to ensure proper surgical management.

2. Procedure

The procedure for placing soft tissue localization device(s) involves several key steps that ensure accurate placement and effective guidance for subsequent surgical procedures. The following steps outline the process:

  • Step 1: The physician begins by marking the area of concern on the patient's skin, which corresponds to the location of the lesion identified through imaging studies.
  • Step 2: Imaging guidance is utilized to obtain radiological images of the target tissue. This may involve techniques such as ultrasound or fluoroscopy to visualize the lesion clearly.
  • Step 3: A needle is then advanced into the lesion under imaging guidance. Additional images are taken to confirm that the needle is correctly positioned within the mass.
  • Step 4: For wire localization, a hooked wire is inserted into the lesion at a perpendicular angle using the needle. The wire remains anchored within the mass when the needle is withdrawn, leaving a short length of wire extending out through the skin.
  • Step 5: Alternatively, if a localization device such as a clip, metallic pellet, or radioactive seed is used, a plastic stylette is inserted through the biopsy needle and advanced to the lesion site using radiographic guidance. The localization device is then released into the soft tissue lesion.
  • Step 6: After the localization device is placed, both the stylette and the needle are removed, completing the procedure.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any immediate complications related to the placement of the localization device. Patients may be advised to keep the area clean and dry, and to report any signs of infection or unusual discomfort. Follow-up imaging may be required to confirm the position of the localization device prior to the planned surgical intervention. The physician will provide specific instructions regarding activity restrictions and any necessary follow-up appointments to ensure proper healing and preparation for the subsequent procedure.

LT Left side (used to identify procedures performed on the left side of the body)
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.
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.
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).

X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
