Yes

Under the Mental Health Parity and Addiction Equity Act, insurance must cover substance use treatment at the same level as medical/surgical care. This applies to employer plans, ACA marketplace plans, Medicaid, and Medicare.

What is covered

Medical detox, residential treatment, PHP, IOP, outpatient therapy, MAT medications, psychiatric services, and crisis intervention.

Out-of-pocket costs

Deductible (often $500-$5,000), copays or coinsurance (10-40% of costs), and any services exceeding plan limits. In-network facilities have lower out-of-pocket costs than out-of-network.

Maximizing coverage

Call your insurance before admission. Get pre-authorization when required. Choose in-network facilities. Appeal any denials. Many denials are overturned on appeal.
