I have no idea what it would be, I'm between insurance at this time. On my last insurance a combination of Medicare and Medicaid I would have paid nothing, but I have nothing I'm on SSDI. If your insurance is treating inpatient mental health care differently than medical inpatient I think that's supposed to be illegal now under the ACA. The last time I had regular insurance though work my inpatient stay was about $3000 and that was about 10-15 yrs ago.
