About 33973: Intra-aortic balloon device insertion
Reports insertion of an intra-aortic balloon assist device for temporary circulatory support, with code selection guided by the documented insertion service.
An intra-aortic balloon assist device provides temporary circulatory support by counterpulsation. Placement may be needed for a patient with cardiogenic shock or inadequate cardiac output, including in an acute cardiac-care or post-cardiac-surgery setting. A cardiologist or cardiac surgeon typically performs the procedure in a hospital catheterization laboratory or operating room. The operative or procedure note should identify the balloon device, the insertion service performed, and the clinical reason for support.
Report this insertion code when the documented service matches its CPT definition; distinguish it from other balloon-device insertion codes by the specific procedure and approach documented. 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, Medicare pays the highest-valued procedure in full and reduces the others to 50%. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33973 billing questions
How should this code be distinguished from 33967?
Both involve intra-aortic balloon support, but 33967 identifies percutaneous insertion. Select the code that matches the specific insertion service documented and the applicable CPT definition.
Can removal be reported with this insertion code?
Removal is represented by a separate code, such as 33974. Report removal only when it is performed and documented as a distinct service.
Is modifier 50 appropriate?
No. The CMS bilateral adjustment does not apply, and the service's descriptor or anatomy makes modifier 50 inappropriate.
How does Medicare handle other procedures performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50% when performed in the same session.
What should the procedure note support?
Document the clinical need for temporary circulatory support, the balloon device inserted, and the insertion service and approach performed so the selected code is supported.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
