In simple words: A CT scan of the upper and middle back is done without using any special dye to get clearer images.This helps the doctor see the bones and tissues in this area.

This diagnostic procedure involves a computed tomography (CT) examination of the thoracic spine without the use of contrast material.The provider rotates an X-ray tube and detectors around the patient to produce cross-sectional images. The patient lies on the scanner bed, which moves slowly through the scanner while multiple images are acquired.The images are then viewed and interpreted on a computer monitor, and stored digitally for later review.

Example 1: A patient presents with severe, persistent thoracic pain. A CT scan without contrast is ordered to rule out fractures or other bony abnormalities., A patient with a history of thoracic spine trauma undergoes a follow-up CT scan without contrast to assess healing progress.The patient has an allergy to contrast dye, so the scan is performed without contrast., A patient experiencing numbness and weakness in their arms and legs undergoes a thoracic spine CT scan without contrast. The doctor orders a non-contrast CT scan first to rule out any bony lesions that could explain the patient's symptoms before considering a contrast-enhanced study.

* Patient demographics* Reason for the exam (clinical indication)* Relevant medical history (especially allergies)* Radiologist's interpretation report including measurements and any findings.* Images (stored digitally or as hard copy)

** Oral or rectal contrast administration does not require use of a code including "contrast".Intravenous, intra-articular, or intrathecal contrast would necessitate a code with "contrast" in the description. The use of contrast media may require separate billing depending on payer policies.
