Our son has been in a similar day program for several months now - and sounds similar to Linda's description. difficult child has academics and extensive thereapeutic nets in place - and expresses hatred of the program, but we've seen improvements in his behavior that merit an extension of the timeframe we planned to have him enrolled.
Our school district is footing the bill right now, as they are the ones who referred him to the program. In fact, they bus him to and from the program every day. I am not sure our insurance, which is a fairly decent plan, would pick up any of it either, if they were billed. So sad. difficult child was referred to the day treatment after a horrendous start to the school year and a month-long inpatient stay at the psychiatric hospital.
We had initially expected our difficult child to be in the program for about a month - but that has stretched out - and I suspect that he will be in there at least through the end of this school year. Apparently, they also have a summer program at this particularly day treatment facility, so he may even benefit from that, too. Depending on what happens with medications/behavior, he may be in the program longer. I have learned to attempt not to try to see too far into the future, as things can turn on a dime.
We are fortunate, because our difficult child somehow manages to do well academically, despite his severe emotional issues. I don't know how he retains the things he learns with everything else going on, but he does and we thank God for that. He hates the fact that he cannot attend his "regular" school, with his "regular" friends, etc. When he goes down Meltdown Road for any reason, he always makes a detour down this particular side road in his rantings. However, we are working with a new doctor and adjusting medications and are hopeful for the first time in several years.
The collaborative day treatment program has been good for us, although I was overwhelmed about it at first.
Good luck. I hope this all works out for you.
