Official Description

Radiation therapy management with complete course of therapy consisting of 1 or 2 fractions only

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Radiation therapy management involves the oversight and administration of radiation treatment to patients undergoing therapy for various medical conditions. Specifically, CPT® Code 77431 refers to the management of a complete course of radiation therapy that consists of only 1 or 2 fractions. This abbreviated treatment regimen is particularly relevant for certain conditions that may respond effectively to a limited number of radiation doses. Examples of such conditions include keloids, which are raised scars that can be treated with radiation to reduce their size; heterotopic ossifications, which are abnormal bone growths that can occur in soft tissues; and potential bone metastasis, where cancer has spread to the bones. The process of radiation therapy management encompasses several critical components, including the review of imaging studies such as port films, which help in assessing the treatment area, and a thorough chart review to ensure accurate dosimetry and dose delivery. Additionally, the treatment management includes evaluating the patient's treatment setup and conducting a physical examination or face-to-face encounter to monitor the patient's progress, side effects, and overall response to the radiation therapy. The findings from these evaluations are documented by the radiation oncologist or another qualified medical professional, who will then make informed recommendations regarding the continuation or conclusion of the radiation treatment based on the patient's condition and response.

1. Indications

Radiation therapy management with CPT® Code 77431 is indicated for specific medical conditions that may benefit from a short course of radiation treatment consisting of 1 or 2 fractions. The following conditions are explicitly recognized as suitable for this type of therapy:

  • Keloids - Raised scars that can be effectively treated with radiation to minimize their size and prevent recurrence.
  • Heterotopic ossifications - Abnormal bone growths that occur in soft tissues, which can be managed through targeted radiation therapy.
  • Potential bone metastasis - Situations where cancer may have spread to the bones, and a limited radiation treatment may help alleviate symptoms or control the disease.

2. Procedure

The procedure for radiation therapy management under CPT® Code 77431 involves several key steps that ensure the effective delivery of treatment. Each step is crucial for achieving the desired therapeutic outcomes while monitoring patient safety and response.

  • Step 1: Review of Imaging Studies - The radiation oncologist begins by reviewing port films or other relevant imaging studies. This step is essential for assessing the treatment area and ensuring that the radiation is accurately targeted to the intended site.
  • Step 2: Chart Review for Dosimetry - A thorough review of the patient's medical chart is conducted to evaluate dosimetry, which involves calculating the appropriate radiation dose and treatment parameters necessary for effective therapy.
  • Step 3: Evaluation of Treatment Setup - The patient's treatment setup is evaluated to confirm that the positioning is correct and that the radiation delivery system is functioning properly. This ensures that the radiation is delivered precisely to the targeted area.
  • Step 4: Patient Encounter - A physical examination or face-to-face encounter with the patient is performed to assess their progress, monitor for any side effects, and evaluate the overall response to the radiation therapy. This interaction is vital for addressing any concerns the patient may have and for making informed decisions about the continuation of treatment.
  • Step 5: Documentation and Recommendations - The findings from the evaluations and patient encounters are documented by the radiation oncologist or qualified medical professional. Based on this documentation, recommendations are made regarding whether to continue or conclude the radiation treatment, ensuring that the patient's care is tailored to their specific needs.

3. Post-Procedure

Post-procedure care following radiation therapy management with CPT® Code 77431 involves monitoring the patient for any immediate side effects or complications that may arise from the treatment. Patients are typically advised to report any unusual symptoms or changes in their condition. Follow-up appointments may be scheduled to assess the effectiveness of the treatment and to evaluate the patient's recovery. The healthcare team will continue to provide support and guidance, ensuring that the patient receives comprehensive care throughout their treatment journey.

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.
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
