Most insurance plans cover addiction and mental health treatment. Federal parity law requires it, which means your plan has to treat rehab like it would treat care for a broken leg or a chronic illness. So the answer to the headline question is usually yes.

The real questions are narrower. What matters for you is which levels of care your plan pays for and how much you owe out of pocket. Coverage can vary by:

  • Detox versus inpatient versus outpatient
  • In-network or out-of-network providers
  • Your deductible, copays, and prior authorization rules
