What 36625 covers
This service places a catheter in an artery after the physician surgically exposes the vessel through an incision. It supports arterial blood sampling, continuous pressure monitoring, or transfusion when access is obtained by cutdown rather than a percutaneous approach. It is most often performed by a surgeon or other physician in a facility setting, including during an operation or acute-care treatment.
Choose this code when the documentation supports arterial catheterization by cutdown for sampling, monitoring, or transfusion; a percutaneous approach points to a different code, and long-term catheter use has a separate code. Record the artery, the cutdown approach, the catheter placement, and its clinical purpose. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
