If you have insurance coverage, the facility works to maximize your benefits under the Mental Health Parity and Addiction Equity Act, which requires insurers to cover mental health and substance abuse treatment with the same breadth and depth as medical and surgical benefits. Cost should never be a barrier to recovery—the team can discuss flexible payment arrangements and help uninsured patients explore available resources.
