What 01926 covers
This service supports therapeutic catheter-based procedures directed at intracranial vessels, structures within the heart, or the aorta. Typical cases include endovascular treatment of cerebral aneurysms or other intracranial vascular lesions, intracardiac interventions, and endovascular aortic treatment. An anesthesiologist or CRNA reports the anesthesia service in the procedural facility; the interventional radiologist, neurointerventionalist, cardiologist, or vascular specialist reports the treatment itself.
Choose 01926 for therapeutic interventions involving one of these specified regions, rather than an arterial procedure not otherwise specified or a diagnostic arteriography study. The anesthesia record should identify the intervention, show the patient's preparation and recovery handoff, and document anesthesia start and end times; the operative report should establish the treated site and therapeutic purpose. This code has 8 base units; Medicare payment is (base units + time units) multiplied by the locality's anesthesia conversion factor. Time is recorded in minutes and converted to 15-minute units to one decimal place, from preparation for anesthesia until the practitioner is no longer in personal attendance and the patient can safely enter postoperative care.

01926 billing questions
How does 01926 differ from 01924?
01926 is for therapeutic interventions involving intracranial, intracardiac, or aortic sites. 01924 is for therapeutic interventional radiology involving arteries not otherwise specified.
Is 01926 appropriate for diagnostic arteriography alone?
No. For diagnostic arteriography or venography, compare 01916; 01926 describes anesthesia for a therapeutic intervention at one of its specified sites.
What should the records show?
The anesthesia record should support the anesthesia service and its start and end times. The operative report should identify the treated site and show that the catheter-based procedure was therapeutic.
How are time units counted?
Report anesthesia time in minutes; CMS converts it to 15-minute units, computed to one decimal place. The code has 8 base units, and time units are added under the Medicare anesthesia payment formula.
Does this code report the intervention itself?
No. The anesthesia practitioner reports the anesthesia service; the physician performing the intracranial, intracardiac, or aortic intervention reports the treatment under the applicable procedure code.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
