CPT® Code 77012

Computed tomography guidance for needle placement (eg, biopsy, aspiration, injection, localization device), radiological supervision and interpretation

This code, CPT® 77012, pertains to the use of computed tomography (CT) guidance for various needle placement procedures, including biopsy, aspiration, injection, or the placement of localization devices. The procedure involves the radiological supervision and interpretation of the CT images that are utilized to accurately guide the needle to the target area within the body. During this process, the area of interest is first localized using CT imaging, which provides detailed cross-sectional views of the internal structures. Following localization, the target area is typically anesthetized to minimize discomfort for the patient. Subsequently, a needle is inserted under the guidance of the CT images, allowing for precise placement to perform the intended procedure. This may involve removing tissue samples for biopsy, injecting a therapeutic or diagnostic agent, or localizing a tumor or mass for further evaluation. The CT technology employs multiple narrow X-ray beams that rotate around a single axis, capturing a series of two-dimensional images from various angles. These images are then digitally reconstructed by a computer to create three-dimensional representations, enabling the generation of thin, cross-sectional slices of the area being examined. This advanced imaging technique enhances the accuracy and effectiveness of needle placement procedures, ensuring that healthcare providers can perform interventions with a high degree of precision.
