CPT® Code 71021

Deleted

1. Indications

The radiologic examination of the chest, coded as CPT® 71021, is indicated for various clinical scenarios where detailed imaging of the thoracic structures is necessary. The following conditions may warrant this procedure:

• Evaluation of Pulmonary Conditions This procedure is performed to assess for potential lung diseases, such as pneumonia, tuberculosis, or lung cancer, particularly in the apical regions of the lungs.
• Assessment of Cardiac Issues It is utilized to evaluate the heart's size and shape, helping to identify conditions such as cardiomegaly or heart failure.
• Investigation of Mediastinal Masses The examination aids in the detection and characterization of masses or opacities located in the mediastinum, which may indicate various pathologies.
• Preoperative Evaluation This imaging is often part of the preoperative assessment for patients undergoing thoracic surgery, ensuring that any underlying conditions are identified prior to the procedure.

2. Procedure

The procedure for CPT® 71021 involves several key steps to ensure accurate imaging of the chest. The following outlines the detailed procedural steps:

• Step 1: Patient Positioning for Frontal View The patient is positioned facing the X-ray machine. This frontal view captures a direct image of the chest, allowing for a clear assessment of the heart and lungs.
• Step 2: Patient Positioning for Lateral View After the frontal view is obtained, the patient is turned to position the side of the chest in front of the X-ray source. This lateral view provides a different perspective, which is crucial for evaluating the depth and size of thoracic structures.
• Step 3: Acquisition of Apical Lordotic View For the apical lordotic view, the patient is instructed to arch their back. This positioning is essential for obtaining images of the uppermost regions of the lungs, enhancing visualization of the apices, which may be obscured in standard views.
• Step 4: Radiation Exposure A small burst of radiation is delivered for each X-ray view. The images are then recorded on hard copy film or stored electronically as digital images, ensuring that they can be reviewed and analyzed by healthcare professionals.

3. Post-Procedure

After the completion of the radiologic examination, the patient may be instructed to wait briefly while the images are processed and reviewed. There are typically no specific post-procedure care requirements, as the exposure to radiation is minimal and the procedure is non-invasive. Patients can usually resume their normal activities immediately following the examination. However, healthcare providers may discuss the results of the imaging at a follow-up appointment, where any necessary further evaluations or treatments can be determined based on the findings.
