I'm hoping someone can give me some info on this. I am a newly minted PMHNP living in Wisconsin. I was just hired by a private practice, and the office manager and I have been discussing reimbursement rates for various insurance companies. He is wondering if PMHNPs in WI can be reimbursed for add-on therapy (CPT code 90833). Does anyone know whether this is state and/or insurance provider specific, or can all psych NPs bill for this? I've tried to find the answer on my own and I haven't found anything definitive. Any help is appreciated!
