37213 Thrombolytic infusion Medicare reimbursement rates in Massachusetts

This code describes continued catheter-directed thrombolytic treatment on the second day, after an initial treatment day. The interventional radiologist, vascular surgeon, or another qualified physician manages the ongoing infusion and may exchange the treatment catheter. The service includes the associated fluoroscopic guidance and imaging supervision and interpretation. It is typically performed in a hospital setting for an occluded artery or vein being treated with infused thrombolytic medication.

Report 37213 for the second treatment day, regardless of whether the treated vessel is arterial or venous; the initial-day code distinguishes those vessel types. Documentation should establish the treatment sequence and date, the continuing infusion, and catheter and imaging management. The CMS global period is 0 days, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.
