Official Description

Special medical radiation physics consultation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Special medical radiation physics consultation, identified by CPT® Code 77370, is a specialized service provided during radiation therapy. This consultation is essential when a patient presents with a complex treatment plan that necessitates modifications or when there is a need for in-depth analysis to resolve specific issues related to the treatment. Such complex treatment plans may involve procedures like total body photon irradiation, total skin electron treatment, or the use of custom beam modification devices. Additionally, it may include special blocking techniques designed to protect critical organs from radiation exposure. The consultation encompasses extended patient contact time with a qualified medical physicist, who is responsible for conducting a thorough assessment and generating a comprehensive written report. This report is crucial for the radiation oncologist, as it provides detailed insights and recommendations that inform the redesign or modification of the existing radiation treatment plan, ensuring that the patient's care is tailored to their unique clinical needs.

1. Indications

The special medical radiation physics consultation (CPT® Code 77370) is indicated in specific scenarios where the complexity of the treatment plan requires expert analysis and potential modifications. The following conditions may warrant this consultation:

  • Complex Treatment Plans Patients undergoing radiation therapy with intricate treatment regimens that may need adjustments.
  • Total Body Photon Irradiation Situations where the patient requires comprehensive radiation treatment affecting the entire body.
  • Total Skin Electron Treatment Cases involving extensive skin irradiation that necessitates careful planning and execution.
  • Custom Beam Modification Devices Instances where specialized devices are used to tailor the radiation beams to the patient's anatomy.
  • Special Blocking Procedures Scenarios where specific techniques are employed to shield critical organs from radiation exposure.

2. Procedure

The procedure for a special medical radiation physics consultation involves several key steps that ensure a thorough evaluation and effective planning for radiation therapy. Each step is critical to achieving optimal treatment outcomes.

  • Initial Assessment The qualified medical physicist begins with an initial assessment of the patient's treatment plan, reviewing the existing protocols and identifying any complexities that may require further analysis or modification.
  • Extended Patient Contact During the consultation, the physicist engages in extended contact with the patient, which may include discussions about the treatment process, potential side effects, and the importance of adhering to the modified plan.
  • Analysis of Treatment Plan A detailed analysis of the treatment plan is conducted, focusing on the specific needs of the patient. This may involve evaluating the effectiveness of current techniques and determining if adjustments are necessary to enhance treatment efficacy.
  • Development of Recommendations Based on the analysis, the physicist formulates recommendations for modifications to the treatment plan. This may include changes to radiation dosages, beam configurations, or the implementation of protective measures for critical organs.
  • Comprehensive Written Report Finally, the physicist prepares a comprehensive written report that outlines the findings, recommendations, and any proposed changes to the treatment plan. This report is essential for the radiation oncologist's review and serves as a guide for implementing the modified treatment strategy.

3. Post-Procedure

After the special medical radiation physics consultation, the patient may expect several follow-up considerations. The radiation oncologist will review the comprehensive report provided by the physicist and discuss the recommended modifications to the treatment plan with the patient. It is crucial for the patient to understand the changes and the rationale behind them, as this will help in adhering to the new treatment regimen. Additionally, ongoing monitoring and assessment may be necessary to evaluate the effectiveness of the modified plan and to make further adjustments if required. Patients should also be informed about any potential side effects associated with the new treatment approach and the importance of reporting any unusual symptoms promptly.

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.
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
GC This service has been performed in part by a resident under the direction of a teaching physician
Q1 Routine clinical service provided in a clinical research study that is in an approved clinical research study
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.

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
X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
