How long will Anthem pay for residential rehab?

Anthem bases the length of a residential stay on medical criteria, not a fixed day count.

Indiana Medicaid also pays for naltrexone through those programs, and Vivitrol programs taking insurance appear below for members who prefer a monthly shot.

Anthem Rehab Centers Near the Indiana Dunes, Steuben County Lakes and the Ohio River

Anthem’s Indiana Medicaid plans are statewide with no regional limits, so the plan rules stay the same from the dunes to the Ohio River. Individual HMO members must stay in network outside emergencies, which matters most in rural settings with fewer programs nearby.

Anthem rehab near the Indiana Dunes

Anthem members in Porter County live along the Indiana Dunes, the Lake Michigan shoreline between Portage, Chesterton and Michigan City. Anthem Medicaid, marketplace and employer members using treatment programs near beaches or rehab programs in Portage follow the same authorization rules used statewide.

Anthem rehab near the Steuben County lakes

Anthem members in Steuben County, Indiana’s lake corner near Angola, Lake James and Pokagon State Park, live close to the Michigan and Ohio lines. Anthem’s Indiana plan rules apply to lakeside rehab programs and treatment near Angola, while programs over the state line fall under each plan’s out-of-network rules.

Anthem rehab along the Ohio River

Anthem members in Jefferson and Dearborn counties live along the Ohio River at Madison, Aurora and Lawrenceburg, across from Kentucky. Members can compare rehab centers near rivers and programs around Madison, and Elevance also holds the Blue license in Kentucky and Ohio across the water.

Anthem admission to residential, inpatient, partial hospitalization or intensive outpatient care starts with authorization.

Anthem’s behavioral health crisis line for Indiana Medicaid members, 833-874-0016, answers 24 hours a day.

Anthem rehab in Indianapolis

Anthem’s home market is Indianapolis. Elevance Health is headquartered there, and all four of Anthem’s Indiana Medicaid programs, its marketplace plans and its Medicare Advantage plans are sold side by side. The same Anthem authorization rules cover drug rehab in Indianapolis and Castleton treatment centers on the north side.

Anthem rehab in Bloomington and south-central Indiana

Anthem took over Indiana University Health Plans, an Indiana-only Medicare Advantage and employer plan carrier, after a deal announced in September 2024 and closed at the end of that year. On January 1, 2026 those plans became Anthem Blue Cross and Blue Shield plans, so former members near Bloomington rehab centers now hold Anthem cards.

Anthem rehab in Merrillville and Lake County

Anthem’s HealthLink network gives State of Illinois employee plan members network access in Indiana, and its visitor search sorts members living in Indiana, Kentucky, Ohio and Wisconsin into one group. That helps Illinois state workers living in Lake County who want downtown Merrillville programs close to home.

Anthem rehab in Evansville and Fort Wayne

Anthem’s Hoosier Care Connect plan covers blind and disabled members under 60 in both Vanderburgh and Allen counties, with residential and intensive outpatient care authorized on the same state form. Members there can compare Evansville rehab programs and downtown Fort Wayne treatment centers.

Is Anthem the same as Elevance Health or Carelon?

Not quite. Anthem Blue Cross and Blue Shield is the Indiana health plan, Elevance Health is its Indianapolis parent, and Carelon Behavioral Health, formerly Beacon Health Options, is a sister company Elevance has owned since 2020. Anthem’s Indiana Medicaid behavioral health page names no outside vendor; authorization runs through Anthem’s own lines.

Can I use Anthem for rehab in a different state?

Usually only with the plan’s agreement. Anthem individual HMO certificates from Connecticut, Colorado and New Hampshire pay for out-of-network substance use care only in emergencies or urgent care. For Anthem’s Indiana Medicaid plans, a 2019 quick reference says out-of-network providers need prior authorization for every service, so out-of-state treatment needs the plan’s agreement first.

How much does rehab cost with Anthem?

Anthem costs depend on the line. Indiana Medicaid members pay little or nothing, with HIP Plus members paying a small monthly POWER account contribution and HIP Basic members small copays. Anthem marketplace plans in Indiana come in Bronze, Silver, Gold and Platinum tiers with a deductible and coinsurance, and employer members find their share in the plan’s benefit summary.

Anthem is one route among several for paying for care in Indiana. The Indiana Chamber’s ChamberCare plan moved from Anthem to SIHO on October 1, 2025, so some small business members changed carriers. Self-pay treatment programs and rehabs accepting Medicare are other routes listed here.
