Official Description

Remote afterloading high dose rate radionuclide skin surface brachytherapy, includes basic dosimetry, when performed; lesion diameter up to 2.0 cm or 1 channel

© Copyright 2025 American Medical Association. All rights reserved.

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 in the patient, ensuring that the healthcare provider is not exposed to radiation during the procedure. The procedure is designed to treat lesions with a diameter of up to 2.0 cm or through a single channel, making it a precise and effective option for managing localized skin cancers. The process begins with careful planning, including the selection of an appropriate surface applicator based on the lesion's depth and size, followed by meticulous placement and monitoring throughout the treatment. This method not only reduces the need for surgical intervention but also shortens the overall duration of radiation exposure required for effective treatment.

1. Indications

Remote afterloading high dose rate radionuclide skin surface brachytherapy is indicated for the treatment of specific skin conditions, particularly non-melanoma skin cancers. The following indications are explicitly recognized for this procedure:

  • Non-Melanoma Skin Cancer Treatment of localized non-melanoma skin cancers, which may include basal cell carcinoma and squamous cell carcinoma.
  • Lesion Size Lesions with a diameter of up to 2.0 cm are suitable for this treatment approach.
  • Single Channel Application Cases where treatment can be effectively delivered through a single channel applicator.

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 Applicator Initially, an appropriate size surface applicator is selected based on the lesion's depth and the required treatment margin. This selection is crucial for ensuring that the radioactive source can be accurately delivered to the tumor site.
  • 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 correctly to maximize treatment efficacy.
  • Step 3: Inspection and Adjustment Once the applicators are in place, they are inspected for size, placement, and stability. Any necessary adjustments are made to ensure optimal positioning before proceeding with the 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 accurate delivery of the radioactive source.
  • Step 5: Monitoring the Patient During the procedure, only the patient remains in the treatment 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 precise delivery of the treatment dose.
  • Step 7: Completion of Procedure Upon completion of the treatment, 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 that no residual radiation remains.
  • 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 treatment's effectiveness 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.
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
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.
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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.
CC Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed)
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
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
