Insertion of cranial bone fiducials
The patient presented to ambulatory surgery for placement of cranial fiducial markers in preparation for deep brain stimulation (DBS), at a future encounter. After induction of anesthesia and scalp preparation, the first of the four stab incisions was made in the anterior scalp with a #15 blade. A Penfield #4 was used to scrape the periosteum off the cranial surface. An OsteoMed hand power drill was loaded with the 5mm fiducial marker screw, which was then drilled flush to the skull. After verifying the appropriate placement, the incision was closed with sutures. These steps were subsequently repeated for the other three stab incisions. After closure, the four incisions were dressed with bacitracin ointment, Telfa™ and Tegaderm™. While still under sedation, the patient was transported from the operating room to imaging where a stereotactic Stealth computed tomography (CT) was performed. After completion of the CT, the patient was then transferred to recovery in stable condition. Is it appropriate to report CPT code 20660 , for the fiducial marker placement? Since the marker placement was the only procedure performed, how should the facility report the procedure? ...

Article Overview
This premium article covers a neurosurgical preoperative procedure involving cranial fiducial marker placement and subsequent stereotactic imaging. It is relevant to coders and clinicians working with operative documentation, ambulatory surgery, and imaging workflows tied to deep brain stimulation planning. The article focuses on the procedural context, documentation elements, and related coding considerations without exposing premium coding guidance.
Why This Topic Matters
Cranial fiducial placement is part of the documentation trail for staged neurosurgical care, and correct understanding of the procedure context supports accurate coding review and record interpretation.
