Aetna Behavioral Health & CVS Caremark Coverage 2026
Federal law requires Aetna / CVS Health to cover addiction treatment under the Mental Health Parity & Addiction Equity Act (MHPAEA). Verify your exact Aetna / CVS Health benefits free — no surprises before treatment.
Aetna, now part of CVS Health, covers addiction treatment for approximately 39 million Americans through Aetna Behavioral Health. Aetna covers the full SUD treatment continuum — medical detox, inpatient rehab, PHP, IOP, MAT, and outpatient counseling — under the MHPAEA and ACA.
Since CVS Health acquired Aetna in 2018, members benefit from integrated pharmacy through CVS Caremark — which can significantly reduce MAT medication costs, especially at CVS pharmacies. Some CVS MinuteClinic locations offer buprenorphine prescribing, improving rapid access to opioid use disorder treatment. Aetna also manages Medicaid in several states under the "Aetna Better Health" brand. Coventry Health Care is also an Aetna/CVS Health subsidiary.
