Official Description

Teletherapy, isodose plan (whether hand or computer calculated); simple (1 or 2 parallel opposed unmodified ports directed to a single area of interest)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 77305 refers to the process of creating a teletherapy isodose plan, which is a critical step in the administration of radiation therapy for cancer patients. This procedure involves the careful planning of the distribution of radiation doses to ensure that the targeted area receives the appropriate amount of radiation while minimizing exposure to surrounding healthy tissues. The term "isodose" refers to lines that represent areas receiving the same dose of radiation, which helps in visualizing how the radiation will be delivered. In this context, the planning can be performed either by hand or through computer calculations. The procedure is classified as simple, indicating that it typically involves one or two parallel opposed unmodified ports directed towards a single area of interest. This means that the radiation beams are aligned in a straightforward manner, focusing on a specific treatment area without the need for complex modifications or blocking techniques. The effective planning of these radiation beams is essential for optimizing treatment outcomes and ensuring patient safety during the course of therapy.

1. Indications

The teletherapy isodose plan (CPT® Code 77305) is indicated for patients undergoing radiation therapy for various types of cancer. The specific indications for this procedure include:

  • Cancer Treatment The primary indication for this procedure is the treatment of cancer, where precise radiation delivery is crucial for effective therapy.
  • Single Area of Interest This procedure is specifically indicated when the treatment involves a single area of interest that requires focused radiation delivery.
  • Simple Port Configuration It is indicated when the treatment plan involves one or two parallel opposed unmodified ports, which simplifies the planning process.

2. Procedure

The procedure for creating a teletherapy isodose plan involves several key steps that ensure accurate radiation delivery. These steps include:

  • Step 1: Patient Assessment The process begins with a thorough assessment of the patient, including a review of their medical history, imaging studies, and the specific cancer diagnosis. This information is critical for determining the appropriate treatment area and radiation dose.
  • Step 2: Planning the Isodose Distribution The physician or medical physicist then plans the isodose distribution, which involves calculating the radiation dose that will be delivered to the treatment area. This can be done manually or using computer software designed for radiation therapy planning.
  • Step 3: Setting Up the Treatment Ports The next step involves determining the configuration of the treatment ports. In this case, the plan will utilize one or two parallel opposed unmodified ports, which are aligned to direct the radiation beams towards the single area of interest.
  • Step 4: Verification and Adjustment After the initial plan is created, it is verified for accuracy. Adjustments may be made to ensure that the radiation dose is optimized for the treatment area while minimizing exposure to surrounding healthy tissues.
  • Step 5: Finalizing the Plan Once the plan is confirmed, it is finalized and documented. This plan will guide the radiation therapy sessions, ensuring that the treatment is delivered as intended.

3. Post-Procedure

After the teletherapy isodose plan is completed, the patient will proceed to receive radiation therapy based on the established plan. Post-procedure care may include monitoring the patient for any immediate reactions to the treatment. Patients are typically advised on potential side effects of radiation therapy, which may include fatigue, skin irritation, or localized discomfort in the treatment area. Follow-up appointments will be scheduled to assess the effectiveness of the treatment and to make any necessary adjustments to the ongoing therapy plan. It is essential for healthcare providers to maintain clear communication with the patient regarding their treatment progress and any concerns that may arise during the course of therapy.
