About the B32 Code Range
These CT scans use multiple radiation exposures to make computer-generated views of upper arteries from different planes. They include scans with and without contrast.
The fourth character identifies the thoracic aorta, both common or internal carotid arteries, both vertebral arteries, intracranial arteries, or the right or left pulmonary artery. The fifth identifies high- or low-osmolar contrast, other contrast, or none. Osmolar describes the concentration of dissolved particles. The sixth indicates intravascular optical coherence, imaging inside a blood vessel, or None. The seventh is always None.
Questions About This Page
How many billable codes are in the B32 range?
Of the 36 codes in this range, 35 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 B32 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 upper arteries. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
