CPT® Code 61210

Burr hole(s); for implanting ventricular catheter, reservoir, EEG electrode(s), pressure recording device, or other cerebral monitoring device (separate procedure)

The procedure described by CPT® Code 61210 involves the creation of one or more cranial burr holes, which are openings made in the skull. This surgical intervention is specifically performed for the purpose of implanting various cerebral monitoring devices, including but not limited to ventricular catheters, reservoirs, EEG electrodes, and pressure recording devices. The term "burr hole" refers to the technique of using a specialized drill to create a precise opening in the skull, which is essential for accessing the brain or its surrounding structures. Prior to the creation of the burr hole, the area over the intended site is typically shaved to ensure a sterile environment. The procedure begins with a small incision through the skin and fascia, followed by the separation of overlying muscle and incision of the periosteum, which is the membrane covering the skull. A drill cutter is then employed to penetrate the skull, creating a small initial hole. This hole is subsequently enlarged using a conical or cylindrical burr, and if a larger opening is necessary, a rongeur may be utilized to achieve the desired size. This procedure is classified as a separate procedure, indicating that it is distinct from other surgical interventions that may be performed concurrently.
