Medicine: Cardiovascular System (Bonus Q&A) (December 2015)
December 2015 page 19b Medicine: Cardiovascular System Question: 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? Answer: Yes, new software allows the pressure wire to measure FFR in coronary arteries without the use of a pharmacological stress agent. These studies are referred to as iFR...

Article Overview
This article is a short cardiovascular coding Q&A from CPT® Assistant that addresses coronary catheterization-related pressure-wire measurement scenarios. It is useful for coders, billers, and auditors who work with cardiovascular medicine and need to understand how the discussion relates to CPT reporting, including a modifier-based reduced-service situation. The piece focuses on a single practical question and answer rather than a full guideline article.
Why This Topic Matters
Cardiovascular coding often involves closely related procedures with subtle reporting differences. This Q&A helps readers understand the article’s discussion of how a specific coronary pressure-wire study scenario fits within existing CPT reporting concepts and when reduced-service reporting is discussed.
What You Will Learn
- How the article frames a coronary pressure-wire measurement question in cardiovascular coding.
- The general CPT reporting context discussed for coronary artery flow reserve measurement studies.
- The circumstances in which the article discusses reduced-service reporting in a non-pharmacologic setting.
- How the Q&A connects a newer technique to established coding concepts.
