I have been following this forum since I discovered it a month or so ago -- right about the time my 19-year-old difficult child was on the verge of agreeing to go into rehab, out of state. He is there now, and so far, so good, as far as his progress. But I did get word from the facility last week that our insurance has refused to certify difficult child's treatment, on the grounds of medical necessity. The insurance carrier believes our son would be better off in Intensive Outpatient Treatment. I will be working with the rehab facility on an appeal, but I thought I would post here and ask if anyone has done such an appeal and actually prevailed. I'm afraid this appeal will be an exercise in futility, but I'm hoping to hear that it is not impossible to reverse this kind of decision. TIA for any insight you can give!
