CPT® Code 37214

Transcatheter therapy, arterial or venous infusion for thrombolysis other than coronary, any method, including radiological supervision and interpretation, continued treatment on subsequent day during course of thrombolytic therapy, including follow-up catheter contrast injection, position change, or exchange, when performed; cessation of thrombolysis including removal of catheter and vessel closure by any method

The CPT® Code 37214 refers to a specific type of transcatheter therapy that involves arterial or venous infusion for thrombolysis, which is the process of dissolving blood clots. This procedure is distinct from coronary thrombolysis, as it targets vessels other than those supplying the heart. The therapy is initiated on a separate day and may continue for one or more days as necessary to achieve complete thrombolysis. During this ongoing treatment, radiological supervision and interpretation are provided to monitor the effectiveness of the therapy. The procedure includes follow-up diagnostic angiography, which involves the injection of contrast material to visualize the blood vessels and assess the impact of the thrombolytic agent. If required, the position of the catheter can be adjusted to optimize the delivery of the thrombolytic agent. This adjustment may involve the use of a guidewire to facilitate the repositioning of the catheter. The infusion of the thrombolytic agent continues until the desired outcome is reached, which is either the complete dissolution of the thrombus or the lysis of all treatable occlusions. Once the thrombolysis is deemed complete, the catheter is removed, and a closure method is employed to secure the vessel, which may include the use of a closure device or manual compression to ensure hemostasis. This code is specifically used for the subsequent day of therapy that encompasses the cessation of thrombolysis, catheter removal, and vessel closure, distinguishing it from the initial day of treatment, which is reported separately under a different code.
