Most people arrive at this question already stressed about money on top of everything else, and we want to answer it plainly. For most plans, yes, insurance covers rehab. Federal parity law requires addiction and mental health treatment to be covered much like any other medical care, so coverage itself is rarely the real hurdle. The practical questions are which levels of care your plan approves (detox, residential, outpatient) and what your share of the cost will be. We can help you sort out both.
