Therapeutic radiology treatment planning; simple

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Therapeutic radiology treatment planning is a critical process in the management of cancer and other conditions requiring radiation therapy. This planning phase is essential for determining the most effective way to deliver radiation to a tumor while minimizing exposure to surrounding healthy tissues. The procedure involves a comprehensive review of the patient's medical history, including records, pathology reports, and imaging studies, which may include X-rays, CT scans, or MRIs. During the initial consultation, the radiation oncologist or a qualified healthcare professional gathers pertinent information from the patient to inform the treatment strategy. The planning process includes ordering and interpreting special tests, creating computer-generated treatment plans, and conducting simulations to visualize the treatment approach. The healthcare provider identifies the areas affected by the disease, selects the appropriate types and methods of radiation treatment, and specifies the exact areas to be treated. Additionally, the sequencing of treatment modalities is determined, and any necessary treatment devices are designed or selected. The radiation dose and duration of therapy are also established during this phase. The initial treatment plan is developed before any radiation therapy begins and is subject to ongoing review and modification as the treatment progresses. This ensures that the plan remains effective and responsive to the patient's needs throughout the course of therapy. CPT® Code 77261 specifically denotes the planning of simple therapeutic radiology treatment, which may involve a single area of interest, a single port, or simple parallel opposed ports with minimal or no blocking. This code is distinct from other codes such as 77262 and 77263, which represent intermediate and complex treatment planning, respectively, each involving more intricate techniques and considerations.

1. Indications

The indications for therapeutic radiology treatment planning are primarily centered around the need to effectively target tumors while safeguarding normal tissues from unnecessary radiation exposure. The following conditions may warrant this procedure:

  • Cancer Diagnosis Patients diagnosed with various types of cancer requiring radiation therapy as part of their treatment regimen.
  • Localized Tumors Tumors that are localized and can be targeted with precision radiation techniques.
  • Recurrence of Cancer Situations where cancer has recurred in a previously treated area, necessitating a new treatment plan.
  • Palliative Care Patients requiring palliative treatment to relieve symptoms caused by tumors.

2. Procedure

The procedure for therapeutic radiology treatment planning involves several critical steps to ensure the effective delivery of radiation therapy. Each step is designed to gather necessary information and create a comprehensive treatment plan.

  • Step 1: Patient Consultation The process begins with an initial consultation where the radiation oncologist reviews the patient's medical history, including previous treatments, pathology reports, and imaging studies. This step is crucial for understanding the patient's specific condition and treatment needs.
  • Step 2: Ordering Tests The oncologist may order additional special tests or imaging studies to gather more detailed information about the tumor's characteristics and its relationship to surrounding tissues. This data is essential for accurate treatment planning.
  • Step 3: Treatment Planning Using the information gathered, the oncologist develops a treatment plan that specifies the type(s) and method(s) of radiation therapy to be used. This includes determining the areas to be treated and the sequencing of treatment modalities.
  • Step 4: Simulation A simulation may be conducted to visualize the treatment approach. This step helps in determining the precise angles and positions for radiation delivery, ensuring that the tumor receives the intended dose while minimizing exposure to healthy tissues.
  • Step 5: Design of Treatment Devices If necessary, the oncologist designs or selects treatment devices that may be required for the delivery of radiation. This could include custom shields or blocks to protect normal tissues.
  • Step 6: Dose Specification The final step involves specifying the radiation dose and duration of therapy. This information is critical for ensuring that the treatment is both effective and safe for the patient.

3. Post-Procedure

After the therapeutic radiology treatment planning is completed, the patient will typically undergo a review of the treatment plan before the initiation of therapy. It is important for the oncologist to communicate the details of the plan to the patient, including the expected outcomes and any potential side effects. Throughout the course of therapy, the treatment plan may be reviewed and updated as necessary to adapt to the patient's response to treatment. Continuous monitoring and adjustments ensure that the radiation therapy remains effective and aligned with the patient's evolving needs.

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.
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
X2 Continuous/focused services: for reporting services by clinicians whose expertise is needed for the ongoing management of a chronic disease or a condition that needs to be managed and followed with no planned endpoint to the relationship; reporting clinician service examples include but are not limited to: a rheumatologist taking care of the patient's rheumatoid arthritis longitudinally but not providing general primary care services
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.
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.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
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.
