2025 CPT code 77306
(Active) Effective Date: N/A Revision Date: N/A Radiology Procedures - Teletherapy Isodose Plan; Simple Radiation Oncology Treatment Feed
A simple teletherapy isodose plan using one or two unmodified ports directed to a single area, including basic dosimetry calculations.
Modifiers may apply depending on the circumstances of service. Consult the most current CPT manual for allowed modifiers.Modifier 26 (professional component) may be used when appropriate.
Medical necessity is established by a physician's order documenting the diagnosis of cancer, the need for radiation therapy as part of the treatment plan, and the justification for a simple versus complex isodose plan based on the size, location, and shape of the target volume and surrounding organs at risk.
The radiation oncologist or medical physicist is responsible for creating this plan under the direction of the treating physician. This involves determining the appropriate radiation dose, the optimal angle of radiation delivery, and ensuring equal intensity of radiation distribution across the target area. The medical dosimetrist may assist in these calculations.

In simple words: This medical code covers the creation of a radiation treatment plan.The doctor figures out the best way to deliver radiation to the cancer, using one or two simple entry points. They calculate the precise amount of radiation needed and where it should be focused to target the cancer while protecting healthy tissue.
CPT code 77306 represents the creation of a simple teletherapy isodose plan. This involves planning the radiation dose distribution using one or two unmodified ports directed at a single area of interest within the patient's anatomy.The plan includes basic dosimetry calculations to determine the appropriate radiation dose and its distribution. This is a crucial step in external beam radiation therapy, ensuring accurate and effective treatment delivery while minimizing damage to surrounding healthy tissues. The plan is created using either manual plotting or computer calculations to achieve equal radiation intensity across the treatment field.
Example 1: A patient with prostate cancer requires external beam radiation therapy.A simple isodose plan is created using two parallel opposed ports to deliver radiation to the prostate while sparing surrounding organs., A patient with lung cancer needs radiation treatment. A single port is used to target a small, well-defined tumor in the lung, creating a simple isodose plan to minimize radiation exposure to healthy lung tissue., A patient with a brain tumor requires radiation treatment. A simple isodose plan is created using two parallel opposed ports to target the tumor while minimizing radiation exposure to healthy brain tissue.
Physician's order specifying the treatment plan, including target area, dose, and number of ports.Images (CT, MRI, PET) delineating the target volume and organs at risk.Calculations demonstrating dose distribution and conformity to the target volume.Documentation supporting medical necessity for the radiation therapy.
