Intravascular Distal Coronary Blood Flow Velocity Measurement (93571-93572) (April 2000)
April 2000 pages 1-3 Intravascular Distal Coronary Blood Flow Velocity Measurement (93571-93572) Intravascular distal coronary blood flow velocity measurement, CPT codes 93571 and 93572 , is an invasive procedure employing a miniaturized Doppler transducer mounted at the tip of a specialized guide wire to record intravascular coronary blood flow velocity measurement distal to a coronary lesion (prior and subsequent to pharmacologic stress). This device is small enough to be advanced beyond a coronary lesion without significantly increasing the occlusion, which would invalidate the distal flow measurements. Codes 93571 and 93572 are different from other cardiac stress test codes that explicitly...

Article Overview
This premium article reviews intravascular distal coronary blood flow velocity measurement as it relates to cardiac catheterization and coronary intervention. It is written for coding professionals, cardiology billers, and clinical documentation staff who need to understand the scope of the service, where it fits among other cardiac and vascular diagnostic studies, and the general reporting framework discussed in the article. The piece also includes a clinical vignette and procedure overview to orient readers to the type of documentation and workflow addressed.
Why This Topic Matters
Accurate understanding of this topic helps coders and billing staff distinguish this invasive coronary measurement from noninvasive cardiac and vascular studies and recognize the article’s discussion of add-on code reporting in cardiology workflows.
