About the BT1 Code Range
The ICD-10-PCS root operation Fluoroscopy (code BT1) refers to a diagnostic imaging procedure that uses continuous X-ray to visualize the urinary system in real time. This operation helps capture dynamic internal images, often enhanced with contrast media to better outline structures.
Within the Imaging classification, fluoroscopy codes specify the precise urinary structures examined, including the Bladder, Kidneys (right, left, or bilateral), Ureters, Urethra, and Ileal Diversion Loop. For example, code BT100ZZ indicates fluoroscopy of the Bladder using High Osmolar Contrast, while BT11ZZZ denotes fluoroscopy of the Right Kidney without contrast. The range also covers combined examinations, such as BT14ZZZ for fluoroscopy of Kidneys, Ureters, and Bladder. Different contrast types like High Osmolar, Low Osmolar, and Other Contrast further specify imaging variations to accommodate patient needs and diagnostic goals. Using accurate fluoroscopy codes ensures detailed reporting of urinary system imaging procedures.
Questions About This Page
How many billable codes are in the BT1 range?
Of the 53 codes in this range, 52 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 BT1 range classify?
The range classifies Fluoroscopy procedures, single plane or bi-plane real time display of an image developed from the capture of external ionizing radiation on fluorescent screen. The image may also be stored by either digital or analog means, 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.
