Most insurance plans do cover rehab. Federal parity law requires that addiction and mental health treatment be covered on the same terms as other medical care, so coverage itself is rarely the question. What varies is which levels of care your plan pays for (detox, residential, or outpatient) and how much you owe out of pocket. We can review your benefits with you, explain deductibles and any prior authorization your plan needs, and tell you plainly what treatment will cost before you commit.
