About the BG2 Code Range

These CT scans use multiple radiation exposures to create computer-generated views in different planes. They image both adrenal glands, the parathyroid glands, or the thyroid gland.

The fourth character names the gland or glands imaged. The fifth identifies High Osmolar, Low Osmolar, Other Contrast, or None. The sixth distinguishes Unenhanced and Enhanced from None; the seventh is always None.

Questions About This Page

How many billable codes are in the BG2 range?

Of the 22 codes in this range, 21 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 BG2 range classify?

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