CPT® Code 77385

1. Indications

The indications for intensity modulated radiation treatment (IMRT) using CPT® Code 77385 include the following:

• Prostate Cancer IMRT is often indicated for patients with prostate cancer, where precise targeting of the tumor is crucial to minimize exposure to surrounding healthy tissues.
• Breast Cancer This treatment may also be indicated for breast cancer patients, allowing for targeted radiation delivery to the tumor while protecting adjacent structures.
• Other Tumor Sites IMRT can be indicated for various other tumor sites where a physical compensator is utilized to enhance the precision of radiation delivery.

2. Procedure

The procedure for intensity modulated radiation treatment (IMRT) as described by CPT® Code 77385 involves several key steps:

• Step 1: Imaging and Planning The first step in the IMRT process is the acquisition of detailed imaging of the tumor using CT or MRI. This imaging is critical for accurately mapping the tumor's location and shape, which informs the treatment planning process.
• Step 2: Treatment Planning Following imaging, a computerized treatment planning system is employed to calculate the optimal radiation dose. This system generates a plan that specifies how the radiation beams will be shaped and directed to conform to the tumor's three-dimensional structure.
• Step 3: Delivery of Radiation The actual delivery of radiation involves the use of a computer-controlled radiotherapy machine. This machine delivers radiation through multiple small, non-uniform beams that are adjusted to target the tumor precisely while sparing healthy tissue.
• Step 4: Image Guidance and Tracking Throughout the treatment, image guidance and tracking techniques are utilized to ensure that the radiation is delivered accurately to the intended target. This step is crucial for maintaining the precision of the treatment as the patient is positioned for each session.

3. Post-Procedure

After the completion of the intensity modulated radiation treatment (IMRT) procedure, patients may experience some side effects, which can vary based on the treatment area. Common post-procedure care includes monitoring for any immediate reactions to the radiation, managing any discomfort, and providing supportive care as needed. Patients are typically advised to follow up with their healthcare provider to assess the effectiveness of the treatment and to discuss any ongoing symptoms or concerns. Recovery times can vary, and patients may require additional supportive therapies or interventions based on their individual response to treatment.
