About the BT2 Code Range

These CT scans use a computer to turn external radiation exposures into views of the bladder or kidneys from different angles.

The fourth character identifies the bladder, right kidney, left kidney, both kidneys or a kidney transplant. The fifth character identifies high-osmolar, low-osmolar or other contrast, or no contrast. The sixth character can mark imaging both without and with enhancement, or have no qualifier. The seventh character is always None.

Questions About This Page

How many billable codes are in the BT2 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 BT2 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 urinary system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
