What 37193 covers
This service covers catheter-based retrieval of an intravascular vena cava filter. The physician gains vascular access, guides a catheter to the filter, and uses retrieval tools such as a snare to remove it. Interventional radiologists and vascular specialists commonly perform the procedure in a hospital or outpatient procedural suite, often using fluoroscopic imaging and venography to locate the filter and confirm removal.
Report this code for removal of the filter itself, not its placement or repositioning. Documentation should identify the filter, the retrieval approach, and the work performed to capture and remove it. Catheter placement, venography, imaging guidance, and radiological supervision and interpretation are included in the retrieval service. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, Medicare pays the highest-valued procedure in full and other procedures at 50%. Modifier 50 is not appropriate for this single-filter retrieval. Medicare does not pay an assistant at surgery; co-surgeon and team-surgery billing are not permitted.

37193 billing questions
How is retrieval different from filter repositioning?
Use this code when the filter is removed. Code 37192 describes endovascular repositioning or another adjustment that leaves the filter in place.
Are venography and imaging guidance separately reported?
They are included in the filter retrieval service, along with the catheter work integral to removal.
Is modifier 50 appropriate for retrieving a vena cava filter?
No. The service concerns a single vena cava filter, and modifier 50 is not appropriate.
How does Medicare handle another procedure performed in the same session?
The highest-valued procedure is paid in full, and other procedures in that session are paid at 50% under the multiple procedure reduction.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this code. Co-surgeon and team-surgery billing are not permitted.
What documentation supports reporting filter retrieval?
Document that the device was a vena cava filter and describe the catheter-based steps and work used to capture and remove it.
