About the BW2 Code Range

CT scans use multiple exposures to external radiation to create computer-processed images of anatomical regions in different planes.

The fourth character identifies the area: abdomen, abdomen and pelvis, chest and abdomen, chest, abdomen and pelvis, head, head and neck, neck, or pelvic region. The fifth character identifies whether contrast material is high osmolar, low osmolar, another type, or absent. Osmolar describes the concentration of dissolved particles. The sixth character distinguishes unenhanced and enhanced imaging from None. The seventh character is always None.

Questions About This Page

How many billable codes are in the BW2 range?

Of the 57 codes in this range, 56 are billable and valid for inpatient claim submission from October 1, 2026 through September 30, 2027. Table header codes group them but cannot be reported on claims.

What does the BW2 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 anatomical regions. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
