About the BG2 Code Range
The ICD-10-PCS root operation Computerized Tomography (CT Scan) (code BG2) involves obtaining cross-sectional images of the Endocrine System using CT technology. This imaging technique provides detailed visualization of internal structures without invasive procedures.
Within the Imaging section, computerized tomography is utilized to assess specific endocrine organs such as the Adrenal Glands, Parathyroid Glands, and Thyroid Gland. The provided codes indicate variations based on the use and type of contrast agents—including High Osmolar, Low Osmolar, and Other Contrast—and whether imaging is done unenhanced, enhanced, or both (e.g., BG2200Z for CT of bilateral adrenal glands using high osmolar contrast, unenhanced and enhanced). Further, some codes describe scans performed without contrast (e.g., BG22ZZZ). These distinctions in contrast and bilateral or specific gland imaging allow accurate documentation of the diagnostic CT procedures targeting endocrine organs, essential for precise clinical coding and effective patient management.
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, 2025 through September 30, 2026. 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.
