ICD-10-PCS B21 Imaging: Heart Fluoroscopy

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.

List of ICD-10-PCS codes used to specify B21 - Fluoroscopy (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). There are a total of 43 procedure codes in this section.
