Ultrasonic guidance for interstitial radioelement application

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Ultrasonic guidance for interstitial radioelement application, as described by CPT® Code 76965, refers to the use of ultrasound technology to assist in the precise placement of radioactive seeds or pellets during brachytherapy procedures. Brachytherapy is a form of internal radiation therapy where radioactive material is placed directly inside or near a tumor. The ultrasound technique is non-invasive and involves the use of a transducer probe that is placed against the skin. This probe emits high-frequency sound waves that penetrate the body and create a gray scale image of the internal structures. The images produced are crucial for accurately identifying the location of the treatment area, which may include various anatomical sites such as the eye, breast, prostate gland, soft tissues of the head and neck, genitourinary tract, and respiratory tract. To facilitate the imaging process, ultrasonic conduction gel is applied to the skin, enhancing the transmission of sound waves. The transducer probe is then moved over the targeted area, generating real-time images that help healthcare professionals to precisely landmark the site for the implantation of the radioactive seeds or pellets, ensuring effective treatment delivery while minimizing damage to surrounding healthy tissues.

1. Indications

Ultrasonic guidance for interstitial radioelement application is indicated for the following conditions:

  • Brachytherapy for Tumors This procedure is performed to assist in the placement of radioactive seeds or pellets in various types of tumors located in the eye, breast, prostate gland, soft tissue of the head and neck, genitourinary tract, and respiratory tract.

2. Procedure

The procedure for ultrasonic guidance for interstitial radioelement application involves several key steps to ensure accurate placement of the radioactive material:

  • Preparation of the Patient The patient is positioned comfortably, and the area of interest is exposed. Ultrasonic conduction gel is applied to the skin over the targeted site to enhance the quality of the ultrasound images.
  • Application of the Transducer Probe A transducer probe is placed firmly against the skin, and high-frequency sound waves are emitted. The probe is moved over the targeted area to capture real-time images of the internal anatomy.
  • Image Acquisition The ultrasound creates a gray scale image that allows the healthcare provider to visualize the internal structures and identify the precise localization of the treatment area. This step is critical for ensuring that the radioactive seeds or pellets are implanted accurately.
  • Landmarking the Site The images obtained are used to landmark the site for the implantation of the seeds or pellets. This ensures that the radioactive material is placed in the optimal position for effective treatment.

3. Post-Procedure

After the procedure, the patient may be monitored for any immediate reactions or complications. The healthcare provider will provide instructions regarding post-procedure care, which may include activity restrictions and follow-up appointments to assess the treatment's effectiveness. Patients are typically advised to report any unusual symptoms or side effects that may arise following the implantation of the radioactive material.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
TC Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
Q1 Routine clinical service provided in a clinical research study that is in an approved clinical research study
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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.
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
CR Catastrophe/disaster related
Q0 Investigational clinical service provided in a clinical research study that is in an approved clinical research study
XE Separate encounter, a service that is distinct because it occurred during a separate encounter
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
