Neuroendovascular therapy
About 61651: Additional-vessel intracranial drug infusion
Report 61651 for prolonged intra-arterial administration of a therapeutic agent in each additional intracranial vessel treated during neuroendovascular therapy.
This add-on describes prolonged delivery of a pharmacologic agent into an additional intracranial vessel, such as intra-arterial vasodilator treatment for cerebral vasospasm after aneurysmal subarachnoid hemorrhage. A neurointerventional radiologist, endovascular neurosurgeon, or other qualified specialist typically performs the treatment in an angiography suite. The service may also involve prolonged intra-arterial drug delivery for another intracranial vascular indication, such as thrombolytic therapy.
Report 61651 for each additional treated vessel after the initial vessel reported with 61650; it represents another vessel, not extra minutes or another drug dose in the same vessel. The primary service includes catheter placement, diagnostic angiography, and imaging guidance, so those elements are not separately represented by this add-on. Documentation should identify the additional vessel treated and the prolonged pharmacologic administration performed. As an add-on code, 61651 is reported with its primary procedure, and payment falls within that procedure’s global period.
