What 33962 covers
During extracorporeal membrane oxygenation or extracorporeal life support, a clinician may need to adjust an existing peripheral cannula when its position is interfering with effective support or causing a position-related problem. This is a repositioning service, not placement of a new cannula or removal of a cannula. It is typically performed by a surgeon or other clinician managing the ECMO/ECLS cannulation in a hospital setting.
Select 33962 by matching the documented procedure to this code’s full billing code descriptor; the 33957–33964 family distinguishes among specific patient and procedural circumstances. The record should identify the cannula and its peripheral location, the reason for adjustment, the repositioning performed, and the resulting position. CMS assigns 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 the standard multiple procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

33962 billing questions
How do I choose 33962 over another code in the 33957–33964 family?
Match the case to the full billing code descriptor for each candidate code. Document the patient and procedural circumstances that distinguish the selected family code; the CMS short descriptor alone does not provide those details.
Is 33962 for inserting or removing an ECMO cannula?
No. It represents repositioning an existing peripheral cannula. Cannula insertion and removal are separate services with their own codes.
What documentation supports reporting the repositioning?
Document the cannula’s peripheral location, why its position required correction, what adjustment was performed, and the resulting position. The record should also support the patient and procedural circumstances specified by the code descriptor.
Can an assistant surgeon be reported with 33962?
CMS payment for an assistant at surgery is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure’s payment. The code has a 0-day global period.
What happens when 33962 is performed with other procedures in the same session?
Under the standard multiple procedure rule, the highest-valued procedure is paid in full and the other procedures are subject to a 50% reduction. Modifier 50 is inappropriate for this code.
