I see ALL ages for tics/Tourette's and BFRBs (hair pulling, skin picking, nail biting, etc.). For all other treatment I see clients age 18 and older.
I take only Anthem insurance (but not Medicaid or Medicare), otherwise you will self-pay for each session--you can contact your insurance to ask if they will reimburse you if you submit a superbill (I will not submit it).
