Are you a psychiatrist or psychologist? 96101 is a psychological testing code, typically requires prior authorization from insurance companies, and while psychiatrists can use it, imho it is not worth our time and it is almost never appropriate to do so. Insurance companies typically want you to use 90792. If I am doing consults for pre-operative psychiatric evaluation (there is no such a thing as psychiatric "clearance"), then I will either use 99245 (consult code - only reimbursable by certain PPO plans), or I request that the surgeons pay me directly and bundle it into the cost of the procedure.
Typically a good pain psychologist is going to be cheaper and better placed to do evaluations for spinal cord stimulators.
