Official Description

Remote afterloading high dose rate radionuclide interstitial or intracavitary brachytherapy, includes basic dosimetry, when performed; 2-12 channels

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Remote afterloading high dose rate (HDR) radionuclide interstitial or intracavitary brachytherapy is a specialized procedure used in the treatment of certain cancers. This technique involves the precise placement of radioactive sources within or near a tumor to deliver targeted radiation therapy. The term "remote afterloading" refers to the method by which the radioactive material is loaded into the applicators after they have been positioned in the patient, minimizing the exposure of healthcare personnel to radiation. The procedure includes basic dosimetry, which is the calculation and assessment of the radiation dose delivered to the tumor, ensuring that the optimal dose is achieved while protecting surrounding healthy tissues. The use of 2 to 12 channels indicates the number of pathways through which the radioactive source can be delivered, allowing for a tailored approach to treatment based on the specific needs of the patient and the characteristics of the tumor. This method is critical for enhancing the effectiveness of brachytherapy while maintaining safety standards for both patients and medical staff.

1. Indications

The procedure of remote afterloading high dose rate radionuclide interstitial or intracavitary brachytherapy is indicated for the treatment of various malignancies where localized radiation therapy is beneficial. The following conditions may warrant the use of this procedure:

  • Cancer Treatment This procedure is primarily performed for patients with localized tumors, particularly in areas such as the prostate, cervix, or breast, where precise radiation delivery can enhance treatment outcomes.
  • Palliative Care It may also be indicated for palliative treatment to relieve symptoms associated with advanced cancer, such as pain or obstruction caused by tumor growth.

2. Procedure

The procedure for remote afterloading high dose rate radionuclide brachytherapy involves several critical steps to ensure effective and safe treatment delivery. Each step is designed to optimize the placement and dosage of the radioactive source.

  • Step 1: Applicator Placement Initially, empty cylinders or other applicators are implanted in and around the tumor during a separately reportable procedure. This step is crucial as it establishes the framework for where the radioactive sources will be delivered.
  • Step 2: Inspection and Adjustment Once the applicators are in place, they are inspected for size, placement, and stability. Any necessary adjustments are made to ensure that the applicators are optimally positioned to deliver the radiation effectively.
  • Step 3: Connection to Remote Afterloading Machine A transfer tube is selected and connected to the channel applicator in the remote afterloading machine. This connection is essential for the subsequent loading of the radioactive source.
  • Step 4: Patient Monitoring During the procedure, only the patient remains in the room, and they are monitored visually and verbally throughout the entire process to ensure their safety and comfort.
  • Step 5: Loading the Radioactive Source The remote afterloading machine then loads the selected radioactive source into the previously placed applicators. This step is performed with precision to ensure accurate dosing.
  • Step 6: Exposure Control Timers within the machine control the duration of exposure to the radioactive source, allowing for precise delivery of the radiation dose as planned.
  • Step 7: Source Retraction and Safety Verification Upon completion of the procedure, the radioactive source is retracted and safely contained within the afterloading machine. This is verified using a room radiation detector, followed by a patient radiation survey to ensure no residual radiation exposure.
  • Step 8: Applicator Removal Finally, the empty applicators are removed from the patient, concluding the procedure.

3. Post-Procedure

After the completion of remote afterloading high dose rate radionuclide brachytherapy, patients may require monitoring for any immediate side effects related to the procedure. It is essential to ensure that the patient is stable and that there are no complications arising from the placement of the applicators or the radiation exposure. Patients may experience some localized discomfort or swelling, which should be managed appropriately. Follow-up appointments are typically scheduled to assess the treatment's effectiveness and monitor for any potential late effects of radiation therapy. Additionally, patients may receive specific instructions regarding activity restrictions and signs of complications to watch for as they recover.

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.
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.
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.
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
