ICD-10-PCS BN2 Imaging: Skull and Facial Bones Computerized Tomography (CT Scan)

The ICD-10-PCS root operation BN2 - Computerized Tomography (CT Scan) refers to the use of CT imaging techniques to obtain detailed radiographic views of specific body parts, focusing here on the Skull and Facial Bones. This imaging procedure is classified under the Imaging section and captures cross-sectional images to assist in diagnosis and treatment planning.

This operation includes a wide range of codes that specify the exact body parts examined—such as the Skull, Bilateral Orbits, Facial Bones, Mandible, Bilateral Temporomandibular Joints, and Temporal Bones. It also details the use of different types of contrast media, including High Osmolar Contrast, Low Osmolar Contrast, or Other Contrast, as well as studies performed without contrast. For example, BN200ZZ codes a CT scan of the Skull using High Osmolar Contrast, whereas BN23ZZZ represents a CT scan of the Bilateral Orbits without contrast. Accurate selection of these ICD-10-PCS CT scan codes supports precise documentation when imaging skull and facial structures for clinical evaluation.

List of ICD-10-PCS codes used to specify BN2 - Computerized Tomography (CT Scan) (computer-reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation). There are a total of 25 procedure codes in this section.
