About the B21 Code Range
The ICD-10-PCS root operation Fluoroscopy (B21) refers to the use of real-time X-ray imaging to visualize internal structures, aiding diagnosis and treatment. This Imaging procedure captures continuous moving images, often with contrast agents, to assess cardiovascular anatomy.
Within the cardiovascular system, fluoroscopy codes specify detailed examination sites such as the Heart, including Single or Multiple Coronary Arteries and their Bypass Grafts. Important distinctions include the type of contrast used—High Osmolar, Low Osmolar, or Other Contrast—and additional techniques like Laser Intraoperative fluoroscopy. For example, code B2100ZZ represents fluoroscopy of a single coronary artery using high osmolar contrast, while B211Y10 describes fluoroscopy of multiple coronary arteries with other contrast and laser intraoperative approach. This granularity allows precise documentation for procedures targeting specific heart regions, such as the Right or Left Heart, or Internal Mammary Bypass Grafts, ensuring accurate coding aligned with the imaging modality and anatomical focus.
Questions About This Page
How many billable codes are in the B21 range?
Of the 43 codes in this range, 42 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 B21 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 heart. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
