About the B92 Code Range

The ICD-10-PCS root operation Computerized Tomography (CT Scan) (B92) refers to a diagnostic imaging procedure that captures detailed cross-sectional images of specific body parts using computed tomography technology. This operation is classified under the Imaging section.

This operation is utilized across various anatomical regions within the Ear, Nose, Mouth and Throat system to evaluate structures non-invasively. The coding examples illustrate the procedure performed on multiple body parts, such as the Ear (B920ZZZ), Paranasal Sinuses (B922ZZZ), and Larynx (B92JZZZ). These CT scans may involve different contrast agents, including High Osmolar Contrast, Low Osmolar Contrast, or Other Contrast, with codes distinguishing whether the study is unenhanced and enhanced or contrast-only. Appropriately selecting codes, such as B92610Z for a Low Osmolar Contrast CT of Bilateral Parotid Glands, Unenhanced and Enhanced, ensures precise documentation of the procedure's specifics. This detailed coding supports accurate reporting and clinical decision-making for imaging within the head and neck region.

Questions About This Page

How many billable codes are in the B92 range?

Of the 50 codes in this range, 49 are billable and valid for inpatient claim submission from October 1, 2025 through September 30, 2026. Table header codes group them but cannot be reported on claims.

What does the B92 range classify?

The range classifies Computerized Tomography (CT Scan) procedures, computer-reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation, performed on the ear, nose, mouth and throat. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
