SCAI recently recommended that intravascular lithotripsy procedures (HCPCS code C9764) be added to the ambulatory patient group for level 3 endovascular procedures (APC 5193). This APC contains procedures which are similar, both clinically and in resource costs. SCAI also recommended that ambulatory surgery centers (ASC) be compensated for the additional costs when fractional flow reserve studies and intravascular ultrasound. We noted that greater use of these technologies has been shown to prevent unnecessary procedures, improve patient outcomes, and decrease overall cost to the healthcare system.
