About the B21 Code Range
These procedures use radiation to display real-time images of the heart, coronary arteries, and bypass grafts on a fluorescent screen. The display can use one or two planes.
The fourth character distinguishes a single coronary artery from multiple arteries, and a single coronary artery bypass graft from multiple grafts. It also identifies the right heart, left heart, both sides, a right or left internal mammary bypass graft, or another bypass graft. The fifth character identifies high-osmolar, low-osmolar, or other contrast. The sixth character indicates Laser or None; the seventh indicates Intraoperative or None.
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, 2026 through September 30, 2027. 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.
