Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 36640 covers

This code covers arterial catheter placement or cannulation when the access is for extracorporeal circulation or standby use. A surgeon or other physician may establish the arterial access in an operating room for a procedure such as cardiopulmonary bypass. It is distinct from placing a routine arterial line solely for blood sampling or hemodynamic monitoring.

Report the code when the documented purpose of the arterial access supports extracorporeal circulation or standby use; record the indication and catheterization performed. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.
