Common Language Description

The CPT® Code 77059 refers to magnetic resonance imaging (MRI) performed on both breasts. This imaging technique is a noninvasive and non-radiating method that utilizes the magnetic properties of hydrogen atoms present in the body. When exposed to radiowaves within a strong magnetic field, the nuclei of these hydrogen atoms emit radiofrequency signals. A computer then processes these signals, converting the data into high-resolution, tomographic, three-dimensional sectional images of the internal structures of the breasts. This imaging is crucial for evaluating breast tissue and identifying any abnormalities. During the procedure, patients may be administered a sedative to help them remain still while lying on a motorized table that moves into the MRI machine, which is often referred to as a tunnel. Additionally, contrast material may be injected to enhance the quality of the images obtained, allowing for a more detailed examination of the breast tissue.

1. Indications

The procedure associated with CPT® Code 77059 is indicated for various clinical scenarios where detailed imaging of both breasts is necessary. The following conditions may warrant the use of this MRI procedure:

  • Breast Cancer Screening Patients with a high risk of breast cancer may require MRI for early detection and monitoring.
  • Evaluation of Breast Abnormalities MRI is utilized to further investigate abnormalities detected in mammograms or physical examinations.
  • Assessment of Tumor Response This imaging can help assess the effectiveness of treatment in patients undergoing therapy for breast cancer.
  • Preoperative Planning MRI may be performed to provide detailed anatomical information before surgical interventions.

2. Procedure

The procedure for CPT® Code 77059 involves several key steps to ensure accurate imaging of both breasts. The following outlines the procedural steps:

  • Patient Preparation The patient is prepared for the MRI by explaining the procedure and ensuring that she is comfortable. Any metal objects must be removed, and the patient may be asked to change into a gown.
  • Positioning The patient is positioned on a motorized table that will slide into the MRI machine. Proper positioning is crucial for obtaining clear images of both breasts.
  • Administration of Sedative (if necessary) If the patient is anxious or has difficulty remaining still, a sedative may be administered to help her relax during the procedure.
  • Contrast Material Injection (if applicable) If contrast material is indicated for enhanced imaging, it will be injected intravenously. This helps to improve the visibility of certain tissues and abnormalities.
  • Image Acquisition The MRI machine is activated, and the patient will be instructed to remain still while the machine captures detailed images of both breasts. The imaging process typically takes 30 to 60 minutes.
  • Post-Procedure Monitoring After the imaging is complete, the patient is monitored briefly to ensure there are no adverse reactions to the sedative or contrast material.

3. Post-Procedure

Following the MRI procedure coded as CPT® 77059, patients may experience some minor side effects, particularly if a sedative or contrast material was used. It is common for patients to be advised to rest for a short period before leaving the facility. If contrast material was administered, patients may be monitored for any allergic reactions or side effects. The results of the MRI will be interpreted by a radiologist, and a report will be generated for the referring physician. Follow-up appointments may be scheduled to discuss the findings and any necessary further actions based on the results of the imaging.
