CPT® Code 77385

Intensity modulated radiation treatment (IMRT) is an advanced form of radiotherapy that utilizes sophisticated imaging techniques, such as computed tomography (CT) or magnetic resonance imaging (MRI), to accurately map the target area for treatment. This mapping is essential for creating a customized radiation dose that is tailored to the specific shape and size of the tumor. IMRT employs a computer-controlled radiotherapy machine that delivers precise doses of radiation through multiple small, non-uniform beams. These beams are strategically manipulated to conform to the three-dimensional shape of the tumor, allowing for the delivery of higher and more effective radiation doses to the targeted area while minimizing damage to the surrounding healthy tissue. This precision helps to reduce side effects associated with radiation therapy. The complexity of IMRT can vary based on the target area and the specific techniques employed. CPT® Code 77385 is designated for simple IMRT procedures that utilize a minimal number of segments while still achieving an acceptable radiation dose. This code is applicable for treatments involving sites such as the prostate and breast, particularly when a physical compensator is used. In contrast, more complex IMRT procedures that involve a greater number of segments, multiple subfields, or higher intensity radiation doses are reported with CPT® Code 77386. It is important to note that the technical component of image guidance or tracking is included in the procedure, ensuring that the treatment is delivered accurately and effectively.
