What Addiction Treatment Services Does Anthem Cover?
Under the Mental Health Parity and Addiction Equity Act (MHPAEA), Anthem is required to cover substance use disorder treatment at parity with medical/surgical benefits. In practice, this means Anthem Indiana plans cover the full continuum of evidence-based addiction care:
| Service | What It Includes | Prior Auth Required? |
|---|---|---|
| Medical Detox | Medically supervised withdrawal management (3–7 days) | Usually — but often expedited for urgent admissions |
| Residential/Inpatient | 24/7 structured treatment (typically 30 days initial) | Yes — required before admission |
| Partial Hospitalization (PHP) | Day program, 20+ hours/week, live at home | Usually yes |
| Intensive Outpatient (IOP) | 9–19 hours/week, typically 3 evenings | Varies by plan |
| Outpatient Counseling | Individual and group therapy sessions | Generally no for initial visits |
| Medication-Assisted Treatment (MAT) | Suboxone, Vivitrol, methadone + counseling | Medications may require formulary approval |
Anthem Plan Types in Indiana
Anthem offers several plan types in Indiana, and the specifics of your addiction treatment coverage depend on which one you have:
- Employer-sponsored PPO plans: Typically the broadest coverage. PPOs allow you to see both in-network and out-of-network providers, though out-of-network costs are significantly higher. Prior authorization is still required for residential treatment.
- Employer-sponsored HMO plans: Require you to stay in-network and may require a referral from your primary care physician before accessing SUD treatment. Narrower provider network but often lower copays.
- ACA Marketplace plans: Anthem sells individual plans on the Indiana marketplace. All marketplace plans must include essential health benefits, which include substance use disorder treatment. Plans are tiered (Bronze, Silver, Gold, Platinum) with varying deductibles and copays.
- Anthem Medicaid (HIP): Anthem is one of the managed care organizations administering Indiana's Healthy Indiana Plan. HIP covers comprehensive addiction treatment including detox, residential, outpatient, IOP, MAT, and peer recovery support — typically with minimal or no cost-sharing. Anthem HIP member services: 866-408-6131.
- Anthem Medicare Advantage: For beneficiaries 65+ or with qualifying disabilities. Covers SUD treatment as part of Medicare behavioral health benefits.
In-Network vs. Out-of-Network: Why It Matters
One of the most important factors in managing addiction treatment costs with Anthem is network status. The difference can be thousands of dollars:
| Factor | In-Network | Out-of-Network |
|---|---|---|
| Deductible | Standard plan deductible | Separate (often 2x higher) OON deductible |
| Coinsurance | Typically 10–20% after deductible | 30–50% after OON deductible |
| Balance billing | Not allowed — you're protected | Provider can bill you the difference |
| Prior authorization | Facility handles it | You may need to obtain it yourself |
Bottom line: Always choose an in-network Anthem facility when possible. Use Anthem's provider finder or our Indiana facility directory filtered by Anthem insurance to find in-network treatment centers near you.
Prior Authorization: How It Works With Anthem
Prior authorization (preauth) is Anthem's process for reviewing and approving treatment before it begins. It is commonly required for residential and inpatient treatment and sometimes for PHP. Here's what to expect:
- The treatment facility initiates the request — you typically do not need to call Anthem yourself. The admissions team at the rehab center contacts Anthem's behavioral health utilization management department.
- Clinical information is submitted — the facility provides your diagnosis, ASAM level of care recommendation, clinical assessment results, and proposed treatment plan.
- Anthem reviews using ASAM criteria — their clinical reviewers evaluate whether the requested level of care meets medical necessity based on the American Society of Addiction Medicine placement criteria.
- Authorization is granted in increments — Anthem typically authorizes residential treatment in 7–14 day blocks, not the full 30 or 90 days. The facility must submit concurrent reviews to extend authorization.
- Urgent/emergent admissions — for detox or crisis situations, Anthem processes urgent preauth requests within 24–72 hours. Retroactive authorization is possible for emergency admissions.
If prior authorization is denied: You have the right to appeal. See our mental health parity guide for step-by-step appeal instructions including how to file with the Indiana Department of Insurance.
Anthem and Indiana Medicaid (HIP)
Anthem is one of the managed care organizations (MCOs) administering Indiana's Healthy Indiana Plan (HIP). If you have Anthem HIP, your addiction treatment benefits are among the most comprehensive available — and cost-sharing is minimal or zero:
- Covered services: Assessment, medical detox, residential treatment, outpatient counseling, IOP, PHP, MAT (buprenorphine, naltrexone, methadone), peer recovery coaching, and aftercare planning
- Cost to you: HIP Basic members typically have no cost-sharing for behavioral health services. HIP Plus members may have small copays.
- No prior auth for outpatient: Initial outpatient assessments and counseling typically do not require prior authorization under Anthem HIP
- Provider network: Anthem HIP contracts with hundreds of behavioral health providers across Indiana. See the Indiana Medicaid Anthem Behavioral Health reference guide for network details.

What Will You Actually Pay?
