How much does it cost to get checked for ADD at a psychiatrist's office? (with health insurance)(23 yrs old)?

I want to make sure I have the funds to get checked. I want to goto a psychiatrist because I heard that they actually give conclusive tests rather than a family doctor having you fill out a checksheet. I would like to know if I really have it or don't. Thanks for any help.

Well I know on with Blue Cross you have a medical card. On that medical card, it says Primary Care Physician, Specialist, Hospital Emergency Room, Outpatient department and Mental Health/Substance abuse provider, then lists the prices across from each one. On my card, my specialist copay is $25. But you also need a referral from your primary care physician to see the specialist and only have to pay the copay. My mother works at Horizon Blue Cross and I'm under her insurance policy, so I have very good benefits and I'd only have to pay $25. But it really depends on your provider and how good your benefits are. Before you go to the doctors you need to see your regular doctor, get a referral and then call your insurance provider and ask them how much it will be. It should be listed on your insurance card like I said. You also WILL need to bring your insurance card to the visit. Hope I helped. (:
