About 37211: Arterial catheter-directed thrombolysis
Reports catheter-directed thrombolytic infusion for an arterial clot outside the coronary circulation, with imaging supervision and interpretation as part of the service.
An interventional radiologist, vascular surgeon, or other qualified physician uses an arterial catheter to deliver thrombolytic medication to a clot outside the coronary arteries. The service is used for situations such as acute arterial occlusion from thrombus, with treatment performed in an angiography suite or hospital procedure setting. Imaging guidance and interpretation associated with the thrombolytic treatment are included in the service.
Report this code for the arterial infusion treatment, not for venous thrombolysis or the later-day management and discontinuation services described by neighboring codes. The record should identify the treated artery, thrombotic condition, catheter-directed treatment, and imaging work. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. In the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. For bilateral treatment, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

37211 billing questions
When should this code be chosen over 37212?
Use 37211 for catheter-directed thrombolytic infusion in an artery outside the coronary circulation. Code 37212 describes the corresponding venous treatment.
Does this code include imaging work?
Imaging supervision and interpretation associated with the arterial thrombolytic treatment are included. Do not separately report that same imaging work as though it were outside the therapy.
How is later-day thrombolytic management distinguished?
Code 37213 describes continued catheter-directed thrombolytic treatment on a subsequent day. Code 37214 is used when thrombolytic treatment is stopped and the catheter is removed.
What supports reporting 37211?
Document the arterial site and thrombotic condition, catheter-directed delivery of thrombolytic medication, and the imaging work performed for treatment.
How should bilateral treatment and other procedures be handled?
For bilateral treatment, modifier 50 is paid at 150%. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple-procedure reduction.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.
