Official Description

Remote afterloading high dose rate radionuclide skin surface brachytherapy, includes basic dosimetry, when performed; lesion diameter over 2.0 cm and 2 or more channels, or multiple lesions

Common Language Description

Remote afterloading high dose rate (HDR) radionuclide skin surface brachytherapy is a specialized treatment method used primarily for non-melanoma skin cancers. This procedure utilizes a high dose rate of radioactive material delivered directly to the skin surface, allowing for targeted treatment of cancerous lesions while minimizing damage to surrounding healthy tissue. The term "remote afterloading" refers to the technique where the radioactive source is loaded into the applicators after they have been placed on or near the tumor, ensuring that the medical staff can maintain a safe distance during the radiation exposure. The procedure is particularly beneficial for lesions that are larger than 2.0 cm in diameter or when multiple lesions are present, as it allows for effective treatment without the need for surgical intervention. The process begins with careful planning, including the selection of appropriate surface applicators based on the depth and size of the lesions, followed by meticulous placement and adjustment of these applicators to ensure optimal delivery of radiation. The use of a remote afterloading machine further enhances safety and precision, as it automates the loading of the radioactive source into the applicators while the patient is monitored closely. This method not only shortens the duration of radiation treatment but also improves patient comfort and outcomes.

1. Indications

The procedure of remote afterloading high dose rate radionuclide skin surface brachytherapy is indicated for the following conditions:

  • Malignant Skin Lesions Over 2.0 cm: This procedure is specifically indicated for the treatment of skin cancers that exceed 2.0 cm in diameter, allowing for effective radiation therapy targeting larger tumors.
  • Multiple Lesions: The technique is also applicable when multiple skin lesions are present, enabling simultaneous treatment of several areas, which can enhance overall patient management.
  • Use of 2 or More Channels: The procedure is indicated when treatment requires the use of two or more channels, facilitating a more comprehensive delivery of the radioactive source to the affected areas.

2. Procedure

The procedure for remote afterloading high dose rate radionuclide skin surface brachytherapy involves several critical steps to ensure effective treatment:

  • Step 1: Selection of Surface Applicators - Initially, the appropriate size surface applicator is selected based on the determined depth of the lesion and the basic isodose treatment planning. This selection is crucial to ensure that the applicator provides an adequate margin around the tumor for effective radiation delivery.
  • Step 2: Placement of Applicators - The selected surface applicators are then implanted in and around the cutaneous tumor. This step is performed as a separately reportable procedure, ensuring that the applicators are positioned accurately to maximize the treatment's effectiveness.
  • Step 3: Inspection and Adjustment - After placement, the applicators are inspected for size, placement, and stability. Any necessary adjustments are made to ensure that the applicators are optimally positioned for the subsequent radiation treatment.
  • Step 4: 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 safe and precise delivery of the radioactive source.
  • Step 5: Monitoring the Patient - 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 6: Loading the Radioactive Source - The remote afterloading machine then loads the selected radioactive source into the previously placed applicators. Timers within the machine control the duration of exposure to the radioactive source, ensuring that the treatment is delivered accurately.
  • Step 7: Completion of the Procedure - Once the treatment is complete, the radioactive source is retracted and safely contained within the afterloading machine. This step is verified using a room radiation detector, followed by a patient radiation survey to ensure safety.
  • Step 8: Removal of Applicators - 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 skin surface brachytherapy, patients may require specific post-procedure care. It is essential to monitor the treatment site for any signs of adverse reactions or complications. Patients are typically advised to avoid exposing the treated area to direct sunlight and to follow any specific wound care instructions provided by their healthcare provider. Follow-up appointments may be scheduled to assess the effectiveness of the treatment and to monitor for any recurrence of skin lesions. Additionally, patients should be informed about potential side effects, such as skin irritation or changes in pigmentation, and when to seek medical attention if they experience any concerning symptoms.

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.
GV Attending physician not employed or paid under arrangement by the patient's hospice provider
GW Service not related to the hospice patient's terminal condition
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
Q6 Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area
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.
