What 36620 covers
This service covers placing an arterial catheter through the skin for ongoing pressure monitoring or repeated arterial sampling. Anesthesia professionals, intensivists, and other clinicians commonly place an arterial line in an operating room or intensive care setting when continuous blood-pressure data or ready access for blood-gas sampling is needed. The percutaneous method distinguishes this service from placement using an open cutdown.
Select the code when the clinician places the catheter percutaneously, rather than for a one-time arterial blood draw alone. The record should support the reason for access, the arterial site, and catheter placement. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate. Medicare does not pay assistant-at-surgery services for this code; co-surgeons and team surgery are not permitted.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

36620 billing questions
How does this differ from 36625?
36620 is for percutaneous arterial catheter placement. Use 36625 when placement requires a cutdown.
Can 36620 be reported for a single arterial blood draw?
A one-time arterial puncture for blood withdrawal is represented by 36600. This code describes placement of a catheter, not just the puncture and sample.
Can modifier 50 be appended when both arms are catheterized?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Does the 0-day global period include same-day care?
Yes. Same-day preoperative and postoperative care is included in the 0-day global period.
Can an assistant-at-surgery or co-surgeon be paid for this service?
Medicare does not pay assistant-at-surgery services for this code. Co-surgeons and team surgery are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
