Official Description

Computed tomography, thoracic spine; without contrast material, followed by contrast material(s) and further sections

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Computed tomography (CT) of the thoracic spine is a diagnostic imaging procedure that utilizes advanced X-ray technology to create detailed images of the thoracic region of the spine. This procedure involves the use of multiple, narrow X-ray beams that rotate around a single axis, capturing a series of two-dimensional (2D) images from various angles. The resulting images provide a comprehensive view of the thoracic spine, allowing for the assessment of its structure and any potential abnormalities. In this specific procedure, the initial imaging is performed without the use of contrast material, which is a substance that enhances the visibility of certain areas within the body. Following the initial scans, contrast material is administered to further improve the clarity of the images. This contrast material can help highlight specific areas of interest, making it easier for healthcare professionals to identify issues such as bone diseases, fractures, injuries, or congenital defects in the spine, particularly in pediatric patients. The data collected during the CT scan is processed by computer software, which can generate multiple 2D slices of the thoracic spine. These slices can then be combined to create three-dimensional models, providing a more comprehensive view of the spine's anatomy and any pathological conditions present.

1. Indications

Computed tomography of the thoracic spine is indicated for various clinical scenarios where detailed imaging is necessary to evaluate the spine's condition. The following are specific indications for performing this procedure:

  • Bone Disease The procedure is utilized to assess for any abnormalities in the bone structure of the thoracic spine, including conditions such as osteoporosis or tumors.
  • Fractures CT imaging is performed to identify and evaluate fractures in the thoracic vertebrae, which may not be visible on standard X-rays.
  • Injuries The procedure is indicated for patients who have sustained trauma to the thoracic spine, allowing for a thorough examination of potential injuries.
  • Congenital Defects In pediatric patients, CT scans are used to evaluate for congenital anomalies of the spine, aiding in the diagnosis of conditions present at birth.

2. Procedure

The procedure for performing a computed tomography scan of the thoracic spine involves several key steps to ensure accurate imaging and patient safety. The following outlines the procedural steps:

  • Step 1: Patient Preparation The patient is positioned on the CT scanner table, typically lying on their back. It is essential to ensure that the patient is comfortable and understands the procedure. Any metal objects, such as jewelry or clothing with metal fasteners, must be removed to prevent interference with the imaging process.
  • Step 2: Initial Imaging Without Contrast The CT scan begins with the acquisition of images of the thoracic spine without the use of contrast material. This initial phase captures baseline images that provide a clear view of the spine's structure and any existing conditions.
  • Step 3: Administration of Contrast Material After the initial images are obtained, contrast material is administered to enhance the visibility of specific areas within the thoracic spine. This may involve intravenous injection of iodine-based contrast dye, which helps to delineate blood vessels and other structures more clearly.
  • Step 4: Further Imaging With Contrast Following the administration of the contrast material, additional images are taken. This phase allows for a more detailed examination of the thoracic spine, highlighting any abnormalities that may not have been visible in the initial scans.
  • Step 5: Image Processing and Review The images obtained from both phases of the scan are processed using specialized computer software. The physician reviews the resulting images to assess for any suspected problems, such as fractures, bone disease, or congenital defects.

3. Post-Procedure

After the completion of the computed tomography scan of the thoracic spine, the patient may be monitored briefly to ensure there are no immediate adverse reactions to the contrast material, particularly if it was administered intravenously. Patients are typically advised to drink plenty of fluids to help flush the contrast material from their system. The physician will review the images and discuss the findings with the patient, providing necessary follow-up recommendations based on the results of the scan. Any further diagnostic or therapeutic interventions will be determined based on the findings from the CT images.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
