If you have a PPO, you can see any provider, but the insurance will pay more towards the visit if you see providers in your insurance network. There may be a separate deductible if you see out-ot-network providers. You should contact your provider regarding "Mental Health" or "Behavioral Health" benefits to confirm that you have this kind of coverage, to make sure you know which insurance company is responsible for that part of your coverage, and to learn the exact details of your financial responsibilities, which may be very complex. Some insurance plans do not cover mental or behavior health problems.
To understand more about your insurance and your rights, go to California Mental Health Resources.
Psychiatry falls under the category of "mental health" or "Behavioral Health".
