Unfortunately, or fortunately, halfway houses or any other sort of sober living or recovery home are currently not being paid for by insurance companies. The truth is, licensed certification for halfway houses is not offered by California and so, it is not possible for them to obtain insurance contracts.
Irrespective of this, outpatients or treatment centers usually give their clients some sort of subsidized or even a free-living environment. Take note as this is usually unclear. They offer these services because they see it to be convenient, even though most at times the same level of care and accountability is not being offered giving rise to a place which may be harmful to recovering alcoholics and addicts.
