CPT® Code 76380

A computed tomography (CT) limited or localized follow-up study, as described by CPT® Code 76380, is a specialized imaging procedure that focuses on a specific area of interest within the body. This type of study is typically ordered when there is a need to investigate an unusual or abnormal finding that was previously identified during a broader imaging examination. Additionally, it may be utilized for ongoing monitoring of progressive changes in a patient's condition over time or in response to treatment. The CT technique employs multiple narrow X-ray beams that rotate around a single axis, capturing a series of two-dimensional (2D) images from various angles. These images are then processed by advanced computer software to create a three-dimensional (3D) representation of the targeted structure. During the procedure, the patient is positioned on a table that slides into the CT scanner, allowing for the acquisition of detailed images. The result is a set of thin, cross-sectional slices that provide a focused view of the area of concern. By concentrating on a localized region, this approach not only enhances the diagnostic accuracy but also significantly reduces the patient's exposure to radiation compared to more extensive imaging studies.
