Diagnostic mammography, including computer-aided detection (CAD) when performed; bilateral
CPT4 code
Name of the Procedure
Diagnostic mammography, including computer-aided detection (CAD) when performed; bilateral. Commonly referred to as "diagnostic mammogram."
Summary
A diagnostic mammogram is an X-ray imaging procedure used to examine breast tissue for abnormalities. Computer-aided detection (CAD) technology helps radiologists better identify potential issues. This procedure is performed on both breasts to compare tissue and spot any irregularities.
Purpose
Diagnostic mammograms are used to investigate suspicious breast changes such as lumps, pain, nipple discharge, or abnormal findings from a screening mammogram. The goals are to detect breast cancer at an early, more treatable stage, and to evaluate any concerns arising from physical exams or screening tests.
Indications
- Detecting and diagnosing the cause of symptoms like lumps, pain, or nipple discharge.
- Further evaluation of abnormal results from a screening mammogram.
- Monitoring previous breast cancer surgery sites.
- Assessment in individuals with a high risk of breast cancer.
Preparation
- Avoid applying deodorants, lotions, or powders on the day of the exam, as these can affect imaging results.
- Inform your doctor about any breast symptoms or problems.
- Bring prior mammogram images if done at a different facility for comparison.
- Wear a two-piece outfit for convenience, as you'll need to undress from the waist up.
Procedure Description
- You will stand in front of a specialized X-ray machine.
- Each breast is positioned and compressed between two plates to spread the tissue for clear images.
- Multiple X-ray images are taken from different angles.
- CAD software analyzes the images and marks areas that may warrant further review by the radiologist.
- The radiologist interprets both the mammogram and CAD results to identify any abnormalities.
Duration
The procedure typically takes about 30 minutes.
Setting
Diagnostic mammograms are usually performed in a hospital’s radiology department or an outpatient imaging center.
Personnel
- Radiologic technologist positions and operates the mammography machine.
- Radiologist reviews and interprets the mammogram images, aided by CAD technology.
Risks and Complications
- Exposure to a low level of radiation, though the benefits usually outweigh the risks.
- Discomfort or pain from breast compression, which is brief.
- False positives or negatives may lead to additional testing or missed diagnoses.
Benefits
- Early detection of breast cancer, potentially before symptoms appear.
- More accurate and detailed diagnostic information compared to screening mammograms.
- Computer-aided detection technology improves the accuracy of findings.
Recovery
- You can resume normal activities immediately after the procedure.
- Results are typically available within a few days, and a follow-up consultation will be scheduled if abnormalities are found.
Alternatives
- Breast ultrasound: Useful for further evaluation of abnormalities found in mammograms but doesn't replace it.
- Breast MRI: Provides detailed images and is often used for high-risk patients but is more expensive and not widely available.
- 3D mammography (tomosynthesis): Offers more detailed images and may be more effective in certain cases.
Patient Experience
- Patients may feel pressure and brief discomfort during compression but should communicate with the technologist to ensure minimal discomfort.
- Most patients resume regular activities immediately and may feel anxious awaiting results, which are usually provided within a few days. Pain management is generally not required given the brief and minor discomfort involved.
