Arterial catheterization
About 36625: Arterial catheter insertion by cutdown
Reports arterial catheter placement through surgical cutdown for blood sampling, pressure monitoring, or transfusion when percutaneous access is not used.
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.

36625 billing questions
How does this differ from 36620?
This code describes arterial catheterization by cutdown, which involves surgically exposing the artery. Code 36620 is for percutaneous arterial catheterization.
When should 36640 be considered instead?
Use 36640 for arterial catheter placement by cutdown intended for long-term use. This code covers cutdown catheterization for sampling, monitoring, or transfusion.
What documentation supports reporting this code?
Document the artery accessed, the surgical cutdown approach, catheter placement, and the purpose, such as sampling, monitoring, or transfusion.
Can modifier 50 be used for bilateral arterial access?
No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.
How are assistant and co-surgeon services handled?
Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
What care is included in the global period?
The code has a 0-day global period. Same-day preoperative and postoperative care is included.
