When performing heart catheterizations, a new pressure guidewire is used to measure the fractional flow reserve (FFR) in coronary arteries without the use of a pharmacologic stress agent, such as adenosine. This is referred to as instantaneous wave-free ratio (iFR). Is it appropriate to report code 93571 and code 93572 with modifier 52 appended to indicate a reduced service for the iFR? ...

Article Overview
This premium coding article addresses a cardiovascular coding scenario involving coronary catheterization and pressure-wire measurement of fractional flow reserve. It explains the general relationship between a newer wire-based method and existing heart catheterization codes, and it discusses why the topic matters for coders working in cardiology, interventional services, and procedural reporting. The article also touches on the role of a reduced-service modifier in this setting without providing a full coding manual.
Why This Topic Matters
Accurate reporting in interventional cardiology depends on recognizing when newer technology aligns with established procedure categories and when modifier use is being considered. This article is relevant to coders, auditors, and reimbursement staff who review coronary physiology studies performed during heart catheterization.
