Quick answer
Most Cigna health plans cover addiction treatment, including detox, residential care, partial hospitalization, intensive outpatient, outpatient therapy and medication-assisted treatment. Behavioral health benefits are generally managed through Evernorth Behavioral Health. Coverage depends on your plan, network and medical necessity, and higher levels of care often need prior authorization.
Cigna Healthcare mainly serves people through employer plans, along with individual plans in some states. Here’s how Cigna coverage for rehab generally works and what to ask before you start.
What addiction treatment does Cigna cover?
Like other insurers, Cigna follows federal rules. The Affordable Care Act lists substance use disorder services as an essential health benefit for individual and small-group plans. The Mental Health Parity and Addiction Equity Act prevents plans from making addiction coverage harder to use than medical coverage.
Most Cigna plans generally cover these levels of care, subject to your plan and medical necessity:
- Medical detox: supervised withdrawal management
- Residential treatment: live-in care with 24-hour support
- Partial hospitalization (PHP): day treatment several hours a day, most days of the week
- Intensive outpatient (IOP): several sessions a week while you live at home
- Outpatient therapy: individual, group or family counseling
- Medication-assisted treatment (MAT): FDA-approved medicine combined with counseling
Withdrawal from alcohol or benzodiazepines can be life-threatening. Anyone stopping these substances should do so under medical supervision.

Who manages Cigna’s behavioral health benefits?
Evernorth Health Services is part of The Cigna Group. Evernorth Behavioral Health generally manages mental health and substance use benefits for Cigna Healthcare members. In practice, that means Evernorth may handle:
- Prior authorization requests
- Reviews during treatment
- The behavioral health provider network
- Care coordination and case management
Your card may list a separate behavioral health phone number. If it does, that’s usually the best number to call about rehab.
How does Cigna decide what’s medically necessary?
Coverage depends on medical necessity, meaning the care fits your clinical needs. Many insurers and treatment programs use the ASAM Criteria, guidelines from the American Society of Addiction Medicine, to match people to the right level of care. The criteria look at withdrawal risk, physical and mental health, readiness to change, relapse risk and your home environment.
Approvals for residential care and PHP are often given in shorter periods and reviewed as you go. If you still meet criteria, coverage can continue. When you’re ready, you may step down to a lower level of care.
Does Cigna require prior authorization?
For many plans, yes. Prior authorization means approval before treatment begins. It’s common for inpatient detox, residential treatment and PHP, and sometimes for IOP or certain medications. The treatment program usually submits the request. If care is denied, ask for the decision in writing and the criteria used. You have the right to appeal.
How do networks work with Cigna?
In-network programs have a contract with Cigna. Out-of-network programs don’t, and they usually cost you more. Your plan type matters:
- HMO and EPO-style plans: generally in-network only, except emergencies
- Open Access, PPO and POS-style plans: may include out-of-network benefits at higher cost
Out-of-network programs may bill you for the difference between their charge and what Cigna pays. Ask before admission.
What will you pay with Cigna?
Your costs depend on your deductible, copays or coinsurance and out-of-pocket maximum. Benefits differ widely between employers and states. For a general picture, see our guide to the cost of rehab.
Cigna sold its Medicare business to Health Care Service Corporation in 2025. If you have a Medicare plan that used to carry the Cigna name, your plan details may have changed, so check your current card. You can also read about Medicare coverage for rehab.
Does Cigna cover aftercare?
Recovery doesn’t end when a residential or PHP stay ends. Most Cigna plans generally continue to cover step-down care, such as IOP, outpatient counseling, psychiatric visits and medication management, under the same medical necessity rules. Ask your care team to plan the next step before discharge so there’s no gap in care.
Sober living homes are different. They offer substance-free housing and peer support, but they usually aren’t licensed treatment, so health insurance generally doesn’t pay for rent there. Outpatient treatment you receive while living in one may still be covered.
What if Cigna denies your claim?
A denial isn’t always the final word. Ask for the decision in writing, including the reason and the clinical criteria used. Your treatment program can often send more records or request a peer-to-peer review, where its clinician talks with the plan’s reviewer. You can also file a formal appeal, and if that fails, you may be able to request an external review by an independent reviewer. Keep copies of everything and note every call.
What questions should you ask Cigna or Evernorth?
Call the number on the back of your card. Keep notes, including the date, the representative’s name and a call reference number.
