About the B31 Code Range

The ICD-10-PCS root operation Fluoroscopy (code B31) refers to the imaging procedure that uses continuous X-ray to produce real-time moving images of arteries, primarily in the upper body. This operation is classified under the Imaging section, focusing on detailed visualization of vascular structures to assist in diagnosis and treatment planning.

The codes provided cover fluoroscopic examinations of various arteries such as the Thoracic Aorta, Right and Left Brachiocephalic-Subclavian Arteries, and the Common, Internal, and External Carotid Arteries. These studies may vary by the type of contrast used, including High Osmolar Contrast, Low Osmolar Contrast, or Other Contrast, and by whether a Laser Intraoperative Approach is applied. For instance, code B310010 specifies fluoroscopy of the thoracic aorta using high osmolar contrast with a laser intraoperative approach, while code B31RZZZ describes fluoroscopy of intracranial arteries without contrast. These examples emphasize the operation’s capacity to provide dynamic vascular imaging with precise anatomical and procedural detail, essential for targeted clinical care.

Questions About This Page

How many billable codes are in the B31 range?

Of the 190 codes in this range, 189 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 B31 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 upper arteries. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
