CPT® Code 61651

Add-On Code

Endovascular intracranial prolonged administration of pharmacologic agent(s) other than for thrombolysis, arterial, including catheter placement, diagnostic angiography, and imaging guidance; each additional vascular territory (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 61651 involves the endovascular intracranial prolonged administration of pharmacologic agents, specifically excluding thrombolysis. This procedure is primarily utilized to treat conditions such as arterial vasospasm that may occur following a stroke. The pharmacologic agents that can be administered during this procedure include, but are not limited to, papaverine, nicardipine, and verapamil. These agents are crucial in managing vasospasm by relaxing the blood vessels and improving blood flow to the affected areas of the brain. The access to the intracranial blood vessels is achieved through a peripheral artery, which allows for a minimally invasive approach. The procedure is guided by fluoroscopy, a type of imaging that provides real-time visualization of the blood vessels, ensuring accurate placement of the catheter. The process involves several steps, including the introduction of a needle into the artery, threading a thin wire to the targeted vascular area, and performing diagnostic angiography if necessary. This comprehensive approach not only facilitates the administration of the pharmacologic agents but also includes imaging guidance to monitor the procedure's effectiveness and safety.
