Official Description

Stereotactic body radiation therapy, treatment delivery, per fraction to 1 or more lesions, including image guidance, entire course not to exceed 5 fractions

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Stereotactic body radiation therapy (SBRT) is a specialized form of radiation treatment that targets one or more lesions within the body with high precision. This technique employs advanced imaging guidance to ensure accurate delivery of radiation, which is crucial for minimizing damage to surrounding healthy tissues. The treatment is administered in fractions, meaning that the total radiation dose is divided into smaller, manageable sessions, with the entire course of treatment not exceeding five fractions. Unlike traditional radiosurgery, which typically involves a single session, SBRT allows for a more gradual delivery of radiation, making it suitable for larger tumors or those located near critical structures. The process involves the use of computer-aided mapping to determine the exact three-dimensional coordinates of the target lesions, ensuring that the radiation is focused precisely where it is needed. To maintain stability during treatment and to protect healthy tissue, patients are often immobilized using removable frames, masks, or custom-fitted casts. The technology utilized in SBRT primarily involves linear accelerators, which generate high-energy x-rays to deliver the radiation. These machines can move during treatment, directing the radiation beam in various arcs to further reduce exposure to healthy tissues. Both magnetic resonance imaging (MRI) and computed tomography (CT) are employed for imaging guidance, with MRI being the preferred method due to its superior resolution and ability to differentiate between normal and tumor tissues. However, some linear accelerator systems may be compatible only with CT imaging. Overall, SBRT represents a significant advancement in the field of radiation therapy, providing effective treatment options for patients with specific tumor characteristics.

1. Indications

The indications for stereotactic body radiation therapy (SBRT) include the treatment of one or more lesions within the body. This procedure is particularly suitable for patients with tumors that are localized and can benefit from precise radiation delivery. The following conditions may warrant the use of SBRT:

  • Localized Tumors Tumors that are confined to a specific area and have not spread to surrounding tissues.
  • Inoperable Lesions Lesions that cannot be surgically removed due to their location or the patient's overall health status.
  • Recurrence of Cancer Patients with recurrent tumors that have previously been treated with other modalities.
  • Large Tumors Tumors that are larger in size, which may require a fractionated approach to minimize damage to adjacent healthy tissues.

2. Procedure

The procedure for delivering stereotactic body radiation therapy involves several critical steps to ensure effective treatment:

  • Step 1: Patient Preparation Prior to the treatment, the patient is positioned accurately using immobilization devices such as frames, masks, or molds. This step is essential to minimize movement during the procedure and to ensure that the radiation is delivered precisely to the target area.
  • Step 2: Imaging Guidance Advanced imaging techniques, including MRI or CT scans, are utilized to locate the lesions accurately. This imaging provides a detailed view of the tumor's size, shape, and position relative to surrounding tissues, which is crucial for planning the treatment.
  • Step 3: Treatment Planning A treatment plan is developed based on the imaging results. This plan outlines the specific angles and doses of radiation to be delivered, ensuring that the maximum dose is focused on the tumor while sparing healthy tissue.
  • Step 4: Radiation Delivery The actual treatment is delivered using a linear accelerator, which produces high-energy x-rays. The machine is programmed to move in various arcs, directing the radiation beam precisely to the target lesions. Each fraction of treatment is carefully monitored to ensure accuracy.
  • Step 5: Post-Treatment Assessment After each treatment session, the patient's response is evaluated, and any necessary adjustments to the treatment plan can be made based on the observed effects and side effects.

3. Post-Procedure

Following the completion of stereotactic body radiation therapy, patients may experience some side effects, which can vary depending on the location and size of the treated lesions. Common post-procedure care includes monitoring for any adverse reactions, managing pain, and providing supportive care as needed. Patients are typically advised to follow up with their healthcare provider to assess the effectiveness of the treatment and to discuss any ongoing symptoms or concerns. Recovery times can vary, but many patients are able to resume normal activities shortly after treatment, depending on their individual circumstances and overall health.

CR Catastrophe/disaster related
GZ Item or service expected to be denied as not reasonable and necessary
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.
