We were recently involved in the 3 stages for treatment of Parkinson's patients. First stage was for fiducial screw placement, Second was for deep brain stimulation and third was for electrode placement. I have contacted the office of the doctor's that provided the services to get the correct CPT codes so I could get the anesthesia codes and they are not sure what to use. I need the 3 codes for the procedures. Any help will be appreciated.
