Documentation to support 93463

Date: Jun 20, 2022

Question:

"Fractional flow reserve (FFR) of the entire LAD artery lesion was performed. A 6F EBU3.5 LAUNCHER guiding catheter was used to engage the vessel. Once ACT came therapeutic, a Volcano Verrata 014x185cm wire was used and equalized at the guide catheter tip. Guide was engaged and Adenosine was given, the guide was disengaged  with measurements obtained. The iFR of the lesion was measured as 0.83. Baseline Pd/Pa was 0.85. Following administration of 100 mcg of intracoronary adenosine, the FFR was 0.62. Apical LAD wire position. Measurements recorded before nitroglycerin administered. Multiple pressure wire artifacts observed FFR: 0.62. The iFR of the lesion was measured as 0.88. Baseline Pd/Pa was 0.86. Following administration of 100 mcg of intracoronary adenosine, the FFR was 0.82. Apical LAD wire position. Measurement recorded after nitroglycerin 100 mcg IC bolus administered. Multiple pressure wire artifacts observed. FFR: 0.82."

Is this enough to support 93463, or only 93571 will be reported?
