Treatment Centers in Indiana That Accept Ambetter

Does Ambetter Cover Rehab in Indiana?

Yes. Ambetter from MHS covers drug and alcohol rehab in Indiana as part of the mental health and substance use benefit every Ambetter plan must include under the Affordable Care Act. Rehabs that accept Ambetter appear among the Indiana substance use treatment centers listed here.

Ambetter from MHS shares its name with Managed Health Services, Centene’s Indiana Medicaid plan since 1995, but the two are separate products with different rules and costs. Ambetter is the Marketplace brand, MHS serves HIP, Hoosier Healthwise and Hoosier Care Connect, and Wellcare is Centene’s Medicare brand in Indiana. Ambetter’s Indiana office is in Indianapolis.

Does Ambetter Cover Inpatient Rehab in Indiana?

Yes. Centene’s company-wide substance use clinical policy, CP.BH.100 (a 2020 copy), covers inpatient rehab services at ASAM Level 3.7, residential treatment programs at Level 3.5 and supervised living at Level 3.1 across its Marketplace, Medicaid and Medicare lines. Ambetter summaries of benefits from other states list inpatient mental health and substance use care as covered, subject to authorization.

How long will Ambetter pay for residential rehab?

Ambetter decides residential length by medical necessity using ASAM level-of-care guidelines, the criteria named in Centene’s substance use policy, rather than a published day count. A stay at one of the 90-day programs taking insurance continues as long as those guidelines support residential care.

Does Ambetter need prior authorization for inpatient rehab?

Often, yes. Ambetter summaries of benefits from other states, such as North Carolina and Arizona, mark mental health and substance use services with “Prior authorization may be required,” and Ambetter from MHS gives Indiana providers a Pre-Auth Check tool to see which services need it. Members can ask member services at 1-877-687-1182 whether a planned stay needs it.

Does Ambetter Cover Detox in Indiana?

Yes. Centene’s CP.BH.100 policy covers inpatient withdrawal management at ASAM Level 4, the medically managed level used when withdrawal carries medical risk, under its Marketplace line. Medically managed detox centers and residential detox programs appear in the listings, and the program files any authorization with Ambetter.

Does Ambetter Cover Outpatient Rehab in Indiana?

Yes. On Ambetter summaries of benefits from other states, outpatient therapy visits take a copay, often before the deductible, and Centene’s policy covers intensive outpatient taking insurance at Level 2.1 and partial hospitalization at Level 2.5. Facility-based outpatient care usually takes coinsurance rather than a flat copay.

Ambetter’s Virtual 24/7 Care lets members see a mental health professional by computer, tablet or phone, and a care manager can coordinate treatment for complex behavioral conditions. Peer recovery support is also part of Centene’s substance use policy, and online rehab and telehealth programs are shown in the listings.

Ambetter plan design also shapes access. In the 2026 plan families Ambetter describes nationally, Premier plans need no referral to see a specialist, while Value plans, sold only in select counties, assign a primary care provider and need referrals for most care outside that office. An Indiana member holding a Value plan may need a referral before starting outpatient counseling.

Does Ambetter Cover Suboxone, Methadone and Other Addiction Medications?

Yes. The 2026 Ambetter from MHS Indiana drug list places generic buprenorphine and buprenorphine-naloxone films and tablets on Tier 1B, a low-copay tier, with quantity limits and no prior authorization flag. Oral naltrexone is also on Tier 1B, so medication-assisted treatment starts at the plan’s lower drug costs.

Does Ambetter cover Suboxone?

Yes. Ambetter from MHS lists generic buprenorphine-naloxone, the generic form of Suboxone, on Tier 1B of its 2026 Indiana drug list with a daily quantity limit. Brand Suboxone does not appear on that list, so a prescriber would ask Centene Pharmacy Services for an exception. Suboxone programs taking insurance are listed below.

Does Ambetter cover methadone?

Yes, as a clinic service rather than a pharmacy drug. Methadone for opioid use disorder is given at opioid treatment programs, not pharmacies, so the program must be in the Ambetter network for the plan to pay. Methadone clinic programs and oral naltrexone treatment appear in the listings.

Ambetter Rehab Centers Near the Falls of the Ohio, Lake Maxinkuckee and the Hoosier National Forest

Ambetter from MHS sells by ZIP code, and its Indiana page sends shoppers to a coverage area map, so the first question in any setting is whether the program is in network. On the HMO and EPO summaries Centene publishes for Texas, Arizona, North Carolina and Alabama, out-of-network mental health and substance use care is not covered outside emergencies.

Ambetter rehab near the Falls of the Ohio

Ambetter members in Clark and Floyd counties live beside the Falls of the Ohio at Clarksville, across the river from Louisville. Rehab programs near rivers and Clarksville treatment centers on the Indiana bank fall under the Indiana plan, while Kentucky programs count only if they are in the Ambetter from MHS network.

Ambetter members in Marshall and Kosciusko counties live near Lake Maxinkuckee at Culver and the Warsaw lakes. Treatment centers near lakes and Warsaw area rehab programs serve the area, and Ambetter’s coverage area map shows whether a home ZIP code is in the plan’s service area.

Ambetter rehab near the Hoosier National Forest

Ambetter members in Perry and Crawford counties live in the southern Hoosier National Forest around Tell City. Rehabs near national forests can be filtered in the listings, and because Ambetter pays only network programs, a member here should ask each program, including any in Jasper or Evansville, whether it is in the Ambetter from MHS network.

How Do I Find a Rehab That Accepts Ambetter in Indiana?

Start with the listings on this page. Each one carries a phone number, the care levels offered and its accreditation, and you can narrow the list by town, service and insurance. Rehabs accepting private insurance can also be browsed, and each program’s admissions desk can say whether it is in the Ambetter from MHS network.

Ambetter admission to residential or inpatient care starts with authorization. The admitting program sends the request, or the member can phone Ambetter from MHS member services at 1-877-687-1182 (TTY 1-800-743-3333), 8 a.m. to 8 p.m. Eastern, with the program’s name. Centene’s other Indiana plans use the lines below.

Ambetter rehab in Indianapolis

Ambetter from MHS runs its Indiana plans from an Indianapolis office, and Centene also sells Ambetter Health Solutions there, off-exchange plans built for employers that fund an Individual Coverage Health Reimbursement Arrangement. Workers on those plans use the Ambetter network at Indianapolis treatment centers and Lawrence treatment programs.

Ambetter rehab in Fort Wayne and Allen County

Ambetter households in Allen County can include someone on MHS Medicaid, such as a child in Hoosier Healthwise or a disabled adult in Hoosier Care Connect. Each card has its own rules: MHS decides urgent behavioral health authorizations within 24 hours and standard ones within 48 hours, while Ambetter uses its Marketplace process at Fort Wayne drug rehab centers.

Ambetter rehab in Lafayette and West Lafayette

Ambetter members in Tippecanoe County who turn 65 move from Marketplace coverage to Medicare, where Centene’s brand is Wellcare, one of the Medicare Advantage plans Centene lists for Indiana. The switch changes the card and the rules for Lafayette rehab programs and West Lafayette treatment options.

Ambetter rehab in Terre Haute and Vigo County

Ambetter from MHS members in Vigo County who lose income during the year may become eligible for Indiana Medicaid; Centene’s Medicaid plan there is MHS, but members can also choose Anthem or CareSource. Moving from Ambetter to Medicaid means a new authorization for any stay at Terre Haute addiction programs.

Can I use Ambetter for rehab in a different state?

Rarely. Ambetter’s HMO and EPO summaries of benefits from other states show out-of-network mental health and substance use services as not covered, and an Ambetter plan from another state uses that state’s network. Emergency care is covered at the in-network rate anywhere, but planned residential treatment outside the Indiana network would normally fall to the member.

How much does rehab cost with Ambetter?

Ambetter costs depend on the metal tier. Bronze plans have the lowest premiums and highest out-of-pocket costs, Gold the reverse, and Silver sits between. On Silver summaries from other states, therapy takes a flat copay while inpatient, residential and partial hospitalization care commonly take 30 to 40 percent coinsurance after the deductible.

Is Ambetter from MHS the same as Indiana Medicaid?

No. Ambetter from MHS is a Marketplace plan with premiums, deductibles and metal tiers, while MHS is Centene’s Indiana Medicaid plan with Medicaid rules and costs. Ambetter notes that the shared name causes confusion, and a member’s card shows which plan applies.

Ambetter is one of several ways Hoosiers pay for addiction treatment. Each facility page names the plans that program accepts, which may include Medicaid, Medicare or self-pay. Indiana Medicaid options and sliding scale treatment are alternatives when a deductible stands between a member and care.
