My 16yr old has lived in a rehab facility all of 2016. Child support that would have come to me from his father was redirected to the facility. Do I claim him?

Up until he was moved to the facility he was living with me since the divorce almost 10 years ago.  I don't pay any extra money to the facility, just the child support that has been redirected.  Do I claim him as living with me all year?  Do I claim him at all?
