Treatment Centers in Hawaii That Accept Humana
Humana covers drug and alcohol rehab in Hawaii mainly through Medicare, including a group Medicare Advantage PPO for retirees of the Hawaii Employer-Union Health Benefits Trust Fund. Humana does not run a Med-QUEST plan, no longer sells employer medical coverage and does not administer TRICARE in Hawaii, so this page centers on Humana’s Medicare coverage for Hawaii retirees.
Each program on this page comes from government treatment registers and Hawaii licensing records. Listings give the facility’s phone number, the levels of care it provides and any accreditation from The Joint Commission or CARF, which helps a Humana retiree on Oahu, Maui or Hawaii Island pick a program to call.

Common questions about Humana
Answered from what is listed here.
Does Humana cover rehab in Hawaii?
Yes, for retired Hawaii public employees on Humana's Group Medicare Advantage PPO 079/307 through the Hawaii Employer-Union Health Benefits Trust Fund. Humana does not sell a commercial or Med-QUEST plan in Hawaii, so coverage here runs through that Medicare plan.
The plan covers inpatient mental health care, partial hospitalization, intensive outpatient and outpatient substance use visits at the same coinsurance in and out of network.
Rehabs in Hawaiihttps://rehabseekers.com/locations/us/hawaii/Does Humana cover inpatient rehab in Hawaii?
Yes. The Hawaii EUTF Group Medicare Advantage PPO covers inpatient mental health stays at the same coinsurance whether the hospital is in network or not, with the member's doctor notifying Humana before a non-emergency admission.
Medicare Part A behind the plan covers care in a general or psychiatric hospital.
Medicare Inpatient Rehabhttps://rehabseekers.com/insurance-accepted/medicare/medicare-inpatient-rehab/How long will Humana pay for inpatient rehab in Hawaii?
Humana's Hawaii EUTF plan follows Medicare's 190-day lifetime limit on care in a freestanding psychiatric facility, a limit that does not apply to psychiatric care given inside a general hospital. Beyond that rule, each stay runs as long as Humana's review supports it.
Admissions are decided case by case rather than against a fixed number of days.
Medicare Residential Rehabhttps://rehabseekers.com/insurance-accepted/medicare/medicare-residential-rehab/Does Humana need prior authorization for inpatient rehab in Hawaii?
Yes, for some services. The 2026 Hawaii EUTF Summary of Benefits requires prior authorization for certain items and points members to Humana.com/PAL for the current list, so the member's doctor checks before a planned psychiatric or substance use admission.
Humana Group Medicare Customer Care takes these calls at 1-888-908-6518.
Medicare Rehabhttps://rehabseekers.com/insurance-accepted/medicare/Does Humana cover detox in Hawaii?
Yes, through Medicare's hospital and outpatient benefits. Medicare Part A covers inpatient stays where withdrawal is managed in a general or psychiatric hospital, and Part B covers outpatient substance use services that the Hawaii EUTF plan lists at the same coinsurance in or out of network.
Oahu detox programs bill under those Medicare rules.
Medicare Detoxhttps://rehabseekers.com/insurance-accepted/medicare/medicare-detox/Does Humana cover outpatient rehab in Hawaii?
Yes. The 2026 Hawaii EUTF plan lists outpatient group and individual substance use treatment visits in primary care, specialist, urgent care and outpatient hospital settings, plus partial hospitalization and intensive outpatient programs, all at the same coinsurance whether the program is on Oahu, a neighbor island, or out of network.
Prior authorization rules can still apply to some of these services.
Medicare Outpatient Rehabhttps://rehabseekers.com/insurance-accepted/medicare/medicare-outpatient-rehab/Does Humana cover telehealth rehab visits in Hawaii?
Yes. Humana says Medicare covers mental health counseling by phone or video, and some of its Medicare Advantage plans charge nothing for mental health telehealth while others charge a copay. For EUTF retirees on Kauai or Molokai, this adds counseling between visits to an island program without a flight to Honolulu.
Medicare Telehealthhttps://rehabseekers.com/insurance-accepted/medicare/medicare-telehealth/Does Humana cover Suboxone or methadone in Hawaii?
Yes, through Medicare's opioid treatment program benefit. Humana lists methadone for opioid use disorder as covered through opioid treatment programs on its Medicare Advantage plan documents, and Medicare covers buprenorphine and naltrexone the same way.
The Hawaii EUTF summary does not list a separate opioid treatment program row, so retirees should ask Humana about cost before starting at a Honolulu clinic.
Medicare Suboxonehttps://rehabseekers.com/insurance-accepted/medicare/medicare-suboxone/Does Humana cover medications for alcohol use disorder in Hawaii?
Through Medicare drug coverage, yes, within the plan's formulary. Medicare Part D plans must cover antidepressants, anticonvulsants and antipsychotics with limited exceptions, but other drugs such as Antabuse or acamprosate depend on the formulary attached to the retiree's specific plan year.
Retirees look up each medication in that year's formulary before assuming it is covered.
Medicare MAThttps://rehabseekers.com/insurance-accepted/medicare/medicare-mat/Does Humana have a Medicaid plan in Hawaii?
No. Humana Healthy Horizons, its Medicaid brand, operates in Florida, Illinois, Indiana, Kentucky, Louisiana, Ohio, Oklahoma, South Carolina and Virginia, with Wisconsin Medicaid run under the separate iCare name, but Humana does not run a Med-QUEST plan in Hawaii.
Hawaii Medicaid members should look to the state's own Med-QUEST managed-care plans instead.
Medicaid Rehabhttps://rehabseekers.com/insurance-accepted/medicaid/Does Humana administer TRICARE in Hawaii?
No. Hawaii is in the TRICARE West Region, run by TriWest Healthcare Alliance, not Humana Military. Humana Military administers TRICARE East under its current contract, which covers a separate group of states and Washington, D.C.
Hawaii TRICARE beneficiaries reach TriWest at 888-874-9378 rather than Humana's member line.
TRICARE Rehabhttps://rehabseekers.com/insurance-accepted/tricare/Does Humana still offer employer health insurance?
No, not commercial medical coverage. Humana announced in February 2023 that it would exit employer group commercial medical business, covering fully insured, self-funded and Federal Employees Health Benefits plans, phasing it out over 18 to 24 months.
It kept group Medicare, Medicare Supplement, dental, vision and other specialty products, which is the basis for its Hawaii EUTF retiree plan.
Humana, HIhttps://rehabseekers.com/locations/us/hawaii/humana-hi/How do I find a rehab in Hawaii that takes Humana?
Start with the member's doctor, who notifies Humana before a non-emergency admission and checks Humana.com/PAL for any required prior authorization. Humana Group Medicare Customer Care answers at 1-888-908-6518, 7 a.m. to 7 p.m. Hawaii time on weekdays.
Because the EUTF plan is a PPO that pays out-of-network providers at the same level, retirees can also look beyond Oahu to programs statewide or on the mainland.
Rehabs in Hawaiihttps://rehabseekers.com/locations/us/hawaii/Does Humana Cover Rehab in Hawaii?
Yes, for retired Hawaii public employees on Humana’s group Medicare Advantage plan. Humana’s 2026 Summary of Benefits for the Hawaii Employer-Union Health Benefits Trust Fund lists inpatient mental health care, partial hospitalization, intensive outpatient services and outpatient substance use treatment visits, which reach Kaneohe treatment programs and the neighbor islands alike.
Humana is now almost entirely a government-program insurer, built on Medicare Advantage, Medicare drug plans and state Medicaid contracts. In Hawaii it does not run a Med-QUEST plan, left employer commercial medical coverage after a 2023 decision, and does not administer TRICARE here, so rehabs that accept Humana in Hawaii are dealing with its Medicare plans.
Does Humana Cover Inpatient Rehab in Hawaii?
Yes. The Hawaii EUTF plan, Humana Group Medicare Advantage PPO 079/307, covers inpatient mental health stays at the same coinsurance in and out of network, and the member’s doctor must notify Humana before a non-emergency admission. Medicare Part A behind it covers inpatient care in a general or psychiatric hospital, the route into Medicare inpatient rehab.
How long will Humana pay for inpatient rehab in Hawaii?
Humana’s Hawaii EUTF plan carries Medicare’s 190-day lifetime limit on care in a freestanding psychiatric facility, and that limit does not apply to psychiatric care in a general hospital. Beyond that rule, each stay runs as long as Humana’s review supports, so Medicare residential rehab options are weighed case by case.
Does Humana need prior authorization for inpatient rehab in Hawaii?
Yes, for some services. The 2026 Hawaii EUTF Summary of Benefits says the plan requires prior authorization for certain items and services and points members to Humana.com/PAL for the current list. For a planned psychiatric or substance use admission, the member’s doctor notifies Humana in advance, and Humana Group Medicare Customer Care answers at 1-888-908-6518.
Does Humana Cover Detox in Hawaii?
Yes, as part of Medicare’s hospital and outpatient benefits. Medicare Part A covers inpatient stays where withdrawal is managed in a general or psychiatric hospital, and Part B covers outpatient substance use services that Humana’s EUTF plan lists at the same coinsurance in and out of network. Medicare detox programs on Oahu bill under those rules.
Does Humana Cover Outpatient Rehab in Hawaii?
Yes. Humana’s 2026 Hawaii EUTF plan lists outpatient group and individual substance use treatment visits in primary care, specialist, urgent care and outpatient hospital settings, plus Medicare partial hospitalization and Medicare IOP programs, each at the same coinsurance whether the program is in network or not, on Oahu or a neighbor island.
Humana says Medicare covers mental health counseling by phone or video, and that some of its Medicare Advantage plans charge nothing for mental health telehealth while others charge a copay. For EUTF retirees on Kauai or Molokai, Medicare telehealth rehab can add counseling between visits to an island program, without a flight to Honolulu.
Does Humana Cover Suboxone, Methadone and Other Addiction Medications in Hawaii?
Yes, through Medicare’s opioid treatment program benefit. Humana lists methadone for opioid use disorder as a covered service on its Medicare Advantage plan documents, delivered through opioid treatment programs, and Medicare covers buprenorphine and naltrexone the same way. Hawaii EUTF retirees reach Medicare Suboxone programs under those Medicare rules.
Does Humana cover methadone in Hawaii?
Yes. Medicare covers methadone, buprenorphine and naltrexone with counseling and drug testing at Medicare-enrolled opioid treatment programs, and Medicare Advantage plans such as Humana’s must cover at least that much. The Hawaii EUTF summary does not list a separate opioid treatment program row, so retirees ask Humana about cost before starting at methadone clinics in Honolulu.
Does Humana cover medications for alcohol use in Hawaii?
Through Medicare drug coverage, yes, within the plan’s formulary. Humana notes that Medicare Part D plans must cover antidepressants, anticonvulsants and antipsychotics with limited exceptions, and other drugs such as Antabuse for alcohol use or acamprosate depend on the formulary attached to the retiree’s plan year, so retirees look up each drug in that formulary.
Humana Rehab Centers by the Beach, in the Desert and in the Mountains
Humana’s Hawaii EUTF plan is a PPO whose service area reaches counties across the United States, Puerto Rico and the territories, so a retiree can use a program in Kailua-Kona, Kahului or on the mainland at the same coinsurance. The settings below show where that freedom leads on the islands, from Oahu beaches to the Kau Desert.
Humana rehab near the beach
Beach settings for Humana retirees include Lanikai and Kailua on Windward Oahu, Waikiki in Honolulu and the Kihei and Wailea coast on south Maui. Programs near the beach on any of those shores are covered at the same coinsurance in or out of network under the EUTF PPO, though prior authorization rules still apply.
Humana rehab in the desert
Desert treatment in Hawaii means the Kau Desert on the southwest flank of Kilauea, inside Hawaii County on the Big Island. Rehabs in desert regions nearest the Kau district are in Hilo and the Puna district, and a Humana EUTF retiree in Naalehu or Pahala uses the same plan rules and coinsurance as a retiree on Oahu.
Humana rehab in the mountains
Mountain settings for Humana members include Haleakala in Maui County, Mauna Kea and Mauna Loa on Hawaii Island and the Koolau Range above Honolulu. Rehab programs near mountains in Upcountry Maui or Waimea fall under the EUTF plan’s statewide reach, with the doctor notifying Humana before any planned admission, including one in Kula or Makawao.
How Do I Find a Rehab That Accepts Humana in Hawaii?
Browse the listings on this page. Each Hawaii program shows its phone number, levels of care and any accreditation, and the filters narrow the list by city and type of treatment. Humana EUTF retirees can also browse Medicare rehab programs more widely, since the plan pays out-of-network providers at the same level.
Admission with Humana starts with the member’s doctor, who notifies the plan before a non-emergency admission and asks about any prior authorization on Humana’s list. Humana Group Medicare Customer Care is 1-888-908-6518, 7 a.m. to 7 p.m. Hawaii time on weekdays, and the EUTF office answers enrollment questions at 808-586-7390.
| Humana coverage line | In Hawaii? | Where to call |
|---|---|---|
| Group Medicare Advantage PPO for EUTF retirees | Yes, 2026 plan 079/307 | 1-888-908-6518 |
| Other Humana Medicare plans | Humana offers at least one Medicare plan type in all 50 states | 800-457-4708 |
| Employer commercial medical plans | No, Humana exited this business | Not applicable |
| TRICARE | No, Hawaii is in TRICARE West, run by TriWest | 888-874-9378 |
| Med-QUEST (Hawaii Medicaid) | No, Humana is not a QUEST plan | Med-QUEST 1-800-316-8005 |
Humana rehab in Honolulu and East Honolulu
Honolulu retirees on the Humana plan can reach the Hawaii Employer-Union Health Benefits Trust Fund at 808-586-7390, 7:45 a.m. to 4:30 p.m. on state workdays, for Humana enrollment or plan changes. Treatment itself is handled under Humana’s plan rules, including advance notice from the doctor. Rehab programs in Honolulu and Maunawili treatment programs appear below.
Humana rehab in Hilo and East Hawaii
Hilo-area retirees on Humana’s EUTF plan face no in-network barrier, because the plan pays in-network and out-of-network programs at the same coinsurance for inpatient, day-program and outpatient substance use care. A program that takes Medicare is the practical test. Papaikou rehab programs and treatment options in Wainaku are listed.
Humana rehab in Kahului and Central Maui
Central Maui retirees on Humana’s EUTF plan use the same national PPO rules, which matters when an admission means flying from Kahului to Honolulu or the mainland. The doctor still notifies Humana first for a planned stay, wherever the program is. Kahului treatment centers and programs near Maalaea are shown below.
Humana rehab on Molokai
Molokai retirees on the Humana EUTF plan have few island programs to choose from, and the plan’s equal in-network and out-of-network coinsurance means an Oahu or Maui program costs the same share. Telehealth counseling by phone or video can fill gaps between in-person visits. Hoolehua treatment programs and rehab services in Kaunakakai are listed.
Can I use Humana for rehab on the mainland?
Yes, on the Hawaii EUTF plan. Humana describes the PPO’s service area as counties within the United States, Puerto Rico and the other major territories, and its 2026 summary shows the same coinsurance in and out of network for substance use care. A non-emergency admission on the mainland still starts with the doctor notifying Humana.
How much does rehab cost with Humana in Hawaii?
Humana’s 2026 Hawaii EUTF plan charges 10 percent coinsurance for inpatient mental health stays, partial hospitalization, intensive outpatient services and outpatient substance use visits, in or out of network. Retirees on other Humana Medicare plans have different cost sharing, which Humana says mostly takes the form of flat copays and per-day inpatient copays.
Humana is one of several ways Hawaii retirees pay for treatment. Members who also qualify for Med-QUEST can carry Medicaid rehab coverage alongside Medicare, and the Department of Health’s Alcohol and Drug Abuse Division funds treatment through Hawaii CARES. State-funded rehab programs also appear in listings for people between plans.
