Aetna Coverage for Mental Health and Substance Use Treatment

Aetna, now part of CVS Health, typically covers mental health and substance use treatment as part of its behavioral health benefits. Coverage spans levels of care from detox through outpatient, in line with the Mental Health Parity and Addiction Equity Act.

Inpatient & Residential Care

Aetna typically covers medically supervised detox, short-term residential care, and longer-term residential treatment when clinically indicated. Pre-authorization is usually required, and Aetna assigns a case manager to help coordinate care throughout treatment.

Outpatient Programs

Coverage generally extends to intensive outpatient programs (IOP), partial hospitalization (PHP), individual therapy, group counseling, and family therapy. Aetna's behavioral health network includes providers experienced in both mental health and substance use care.

Dual Diagnosis Treatment

Aetna typically covers integrated care for co-occurring mental health and substance use disorders. Plans support comprehensive assessment, coordinated treatment planning, and addressing both conditions together — an approach that tends to support better long-term outcomes.

Verifying Your Aetna Benefits Before Admission

Aetna offers a few ways to confirm your mental health and substance use treatment benefits before you begin care.

Online & Phone Verification

Log into your Aetna member portal to review plan details, or call member services directly. Treatment facilities can also contact Aetna's provider line to verify benefits and request pre-authorization in one call.

  • Copay and coinsurance amounts for behavioral health visits

  • Out-of-network benefits, if you have a PPO or POS plan
