Treatment Centers in Mississippi That Accept Ambetter

Does Ambetter Cover Rehab in Mississippi?

Yes. Ambetter from Magnolia Health covers mental health and substance use disorder services as an essential health benefit, and its Mississippi member tip sheet says copayments, deductibles and treatment limits for behavioral health work the same as for physical health. That parity applies at every Mississippi rehab center in the plan’s network.

Ambetter health plans in Mississippi are private Marketplace insurance, not Medicaid, even though the name echoes Magnolia Health, Centene’s MississippiCAN plan and one of the Mississippi Medicaid plans. Ambetter announced statewide plans for 2026, and its off-exchange Ambetter Health Solutions line for employer ICHRA contributions is also sold in Mississippi.

Does Ambetter Cover Inpatient Rehab in Mississippi?

Yes. Inpatient mental health and substance use care is an essential health benefit on every Marketplace plan, and Ambetter’s summaries flag it as a service where prior authorization may be required. Centene’s substance use policy, written for its Medicaid, Medicare and Marketplace lines, covers inpatient rehab at ASAM levels 4 and 3.7.

Which programs count as in network depends on the plan family. Ambetter’s 2026 state sites describe Ambetter Health Premier plans, with the broadest network and no referrals to see specialists, and Ambetter Health Value plans, with a narrower network, an assigned primary care provider and referrals for most care. Residential rehab with insurance confirms which family applies.

How long will Ambetter pay for residential rehab?

Ambetter decides the length of a stay through prior authorization and review, using ASAM level of care guidelines under Centene’s substance use policy. That policy lists residential treatment at ASAM level 3.5 and supervised living at 3.1, so short-term rehab with insurance continues while the review supports the level.

Does Ambetter need prior authorization for rehab?

Yes, for facility care such as residential, partial hospitalization, intensive outpatient and detox, according to Ambetter’s own answer on rehab coverage. The Mississippi tip sheet explains that nurses and doctors look over each request and tell the member and doctor the decision. Members ask a primary care provider or call 1-877-687-1187 to see whether a service needs it.

Does Ambetter Cover Detox in Mississippi?

Yes. Detox is part of the substance use benefit, and Centene’s policy covers inpatient withdrawal management at ASAM level 4 along with lower withdrawal levels. Because facility-based detox needs prior authorization on Ambetter plans, medical detox programs request it before admission, and on HMO-style plans the program must be in network.

Does Ambetter Cover Outpatient Rehab in Mississippi?

Yes. Ambetter’s Mississippi tip sheet says no doctor’s referral is needed for outpatient behavioral health care, and a member may go to any behavioral health provider in Ambetter’s network. Routine behavioral health visits are due within 10 business days, urgent care within 48 hours and non-life-threatening emergencies within six hours, standards that apply to outpatient rehab services in the network.

Virtual 24/7 Care lets members see a licensed provider by telehealth, and Ambetter’s national benefits page says it includes mental health visits by computer, tablet or phone. Online rehab and telehealth can suit members in rural counties, and care managers can coordinate care for complex behavioral conditions.

Does Ambetter Cover Suboxone, Methadone and Other Addiction Medications in Mississippi?

Yes, through the pharmacy benefit, which Express Scripts runs for Ambetter while Centene Pharmacy Services processes claims and drug prior authorization. The Mississippi tip sheet notes some medications need prior authorization or have limits on age, dosage and maximum quantity, so medication treatment programs check the drug list first.

Does Ambetter cover Suboxone?

Ambetter plans cover prescription drugs on their formulary, and a buprenorphine product such as Suboxone may carry a quantity limit or prior authorization under the tip sheet’s rules. A member or buprenorphine maintenance clinic confirms the specific product and tier with Ambetter at 1-877-687-1187 before the prescription is written.

Does Ambetter cover methadone?

Methadone for opioid use disorder is given at licensed opioid treatment programs, and on an Ambetter plan that care falls under the substance use benefit, which must meet the same cost-sharing rules as physical health care. Methadone treatment programs confirm they are in network, since out-of-network care on HMO plans is generally not covered.

Ambetter Rehab Centers Near National Forests, by Lakes and on the Gulf Coast

Mississippi has no mountains or deserts, but Ambetter members can choose among programs near the state’s pine forests, beside its lakes or on the Gulf of Mexico. Because Ambetter from Magnolia Health was sold statewide for 2026, the same plan rules hold in every county; what changes is whether a given program is in network.

Ambetter rehab near national forests

The Bienville National Forest surrounds Forest and Morton in Scott County, and the Homochitto stretches across Franklin and Amite counties east of Natchez. Rehabs near forest land there follow the same Ambetter prior authorization rules as city programs, with Meridian and Jackson the nearest larger cities for members who want a program closer to home.

Ambetter rehab by lakes

Arkabutla Lake lies in Tate and DeSoto counties, and the Ross Barnett Reservoir borders Madison and Rankin counties outside Jackson. Rehab programs near lakes accept Ambetter only if they are in the plan’s network, and Senatobia treatment programs near Arkabutla are listed with their levels of care and phone numbers.

Ambetter rehab on the Gulf Coast

Bay St. Louis, Gulfport, Biloxi, Ocean Springs and Pascagoula are covered by the same statewide Ambetter plan. Coastal members on HMO or EPO designs need an in-network program, since out-of-network mental health and substance use services are generally not covered on those plans, and beach-area recovery centers check that first, before a member travels to the coast for care.

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

Browse the listings on this page. Each one shows a phone number and the levels of care offered, so a member can call the program directly and ask about the Ambetter network, and listings for intensive outpatient with insurance are filtered the same way. Ambetter’s member services line handles benefit questions, including whether the member’s plan family requires a referral.

Admission for facility care runs through prior authorization. The program sends the request, or the member calls Ambetter from Magnolia Health at 1-877-687-1187, Relay 711, Monday through Friday from 8 a.m. to 8 p.m. Central time. The table shows the Centene plans sold in Mississippi, since one household can hold more than one.

Ambetter rehab in Ridgeland, Madison and Jackson

Ambetter of Magnolia, Inc. underwrites Ambetter in Mississippi from Ridgeland, where Magnolia Health’s office sits on Highland Colony Parkway. Members across Madison, Hinds and Rankin counties use one statewide plan, and Ridgeland treatment centers and north Jackson rehab programs check the Ambetter network and plan family before admission.

Ambetter rehab in Hattiesburg and Laurel

Pine Belt members in Forrest, Lamar and Jones counties, including Hattiesburg, Petal and Laurel, have the same statewide 2026 plans as Jackson. The 24/7 nurse advice line at 1-877-687-1187 answers questions after hours, and downtown Hattiesburg rehab centers can confirm whether a planned admission needs prior authorization.

Ambetter rehab in Meridian and east Mississippi

Meridian and Lauderdale County are inside Ambetter’s statewide 2026 area, and members there choose from the same plan options as the rest of the state. Ambetter says no referral is needed for outpatient behavioral health, so Meridian outpatient programs can book a first visit directly without waiting on a primary care appointment.

Ambetter rehab in Southaven and Olive Branch

DeSoto County members live next to Memphis, but an Ambetter from Magnolia Health plan is a Mississippi plan, and on HMO or EPO designs out-of-network behavioral care is generally not covered. Programs such as Olive Branch rehab services in the Mississippi network are the safer route for a member who wants the plan to pay.

Can a Mississippi member use Ambetter for rehab in another state?

Usually not, apart from emergencies. Ambetter plans are sold state by state through separate licensed issuers, and on the HMO and EPO plan summaries Ambetter publishes, out-of-network mental health and substance use services are not covered, while emergency care is paid at the in-network rate. A Mississippi member planning treatment elsewhere calls Ambetter first.

How much does rehab cost with Ambetter?

Costs follow the metal level. Across Ambetter’s summaries, therapy office visits take a flat copay equal to the primary care copay, often before the deductible, while inpatient, residential and partial hospitalization care take coinsurance after the deductible. Subsidies through the Marketplace, called Advance Premium Tax Credits for premiums, can lower premiums, deductibles and copays for eligible members.

Open enrollment for 2026 coverage ran from November 1, 2025 to January 15, 2026, and people with a qualifying event can enroll at other times. Members who lose coverage can look at sliding scale IOP programs and state funded care in these listings while they arrange new insurance.
