CPT® Code 0148T

Deleted

1. Indications

The procedure associated with CPT® Code 0148T is indicated for various clinical scenarios where detailed imaging of the heart and coronary arteries is necessary. The following conditions may warrant the use of this imaging technique:

• Assessment of Coronary Artery Disease This procedure is performed to evaluate the presence and extent of coronary artery disease, which can lead to significant cardiovascular events.
• Evaluation of Cardiac Structure and Morphology It is utilized to assess the structural integrity and morphology of the heart, identifying any deviations from normal anatomical structures.
• Investigation of Anomalous Coronary Arteries The imaging is crucial for identifying and evaluating anomalous coronary arteries that may affect blood flow to the heart.
• Preoperative Planning This procedure can assist in preoperative assessments for patients undergoing cardiac surgery or interventions, providing essential information about coronary anatomy.

2. Procedure

The procedure for CPT® Code 0148T involves several key steps to ensure accurate imaging of the heart and coronary arteries. The following outlines the procedural steps:

• Preparation of the Patient The patient is prepared for the CT scan, which may include fasting for a specified period prior to the procedure. The healthcare provider will explain the procedure and obtain informed consent.
• Administration of Contrast Material A contrast agent is injected into the patient's bloodstream to enhance the visibility of the heart and coronary arteries during imaging. This contrast material helps to delineate structures and improve image quality.
• Cardiac Gating The imaging process employs cardiac gating, which synchronizes the CT scanner with the patient's heartbeat. The scanner remains inactive during the heart's motion and activates briefly during diastole, capturing high-resolution images while minimizing radiation exposure.
• Image Acquisition The CT scanner rotates around the patient, capturing a series of two-dimensional images from multiple angles. These images are then processed by a computer to create detailed three-dimensional reconstructions of the heart and coronary arteries.
• Post-Processing of Images After the images are acquired, advanced post-processing techniques are applied to generate 3D images and assess the cardiac structures and coronary arteries for any abnormalities.

3. Post-Procedure

Following the completion of the CT imaging procedure, the patient may be monitored for a short period to ensure there are no immediate adverse reactions to the contrast material. It is common for patients to resume normal activities shortly after the procedure, although specific post-procedure instructions may be provided based on individual circumstances. The images obtained will be reviewed by a radiologist or cardiologist, who will interpret the findings and provide a report detailing the results of the imaging study. This report is essential for guiding further clinical management and decision-making regarding the patient's cardiovascular health.
