Impact of the Affordable Care Act on Alcohol Rehab

The Affordable Care Act (ACA) made changes to Medicaid and Medicare, intending to increase the number of Americans who have insurance. It allows young adults to stay on their parent’s insurance until age 26 and prevents anyone with pre-existing conditions from health insurance denials. The ACA also expanded income eligibility requirements based on the federal poverty level. The expansions have helped millions of people qualify for Medicaid alcohol rehab, Medicare, and other health insurance plans through the government’s healthcare marketplace.²

Who Qualifies for Medicaid Alcohol Rehab?

Medicaid is a health insurance program for adults over 18, and the Children’s Health Insurance Program (CHIP) is for anyone under 18 who meets specific criteria. Medicaid is a joint funding program between the federal government and the state in which you live. Therefore, eligibility criteria may vary per state.³

The most recent data from 2024 reports reveal close to 7.2% of Medicaid enrollees from ages 12-64 have a diagnosed substance use disorder.³

Eligibility requirements are based on the folllowing:⁴

Income-based on the modified adjusted gross income (MAGI)
Household size
Disability
Family status
Other factors determined by each state
Participation in certain programs like foster care and SSI
S. citizenship or qualified alien

States can choose to be flexible with the Medicaid options they provide to certain eligibility groups:⁵

Low-income children
Children in the welfare system
Pregnant women, low-income or non-low-income
Caretaker relatives
Adults without dependents
Non-citizens
Medically needy

These requirements vary depending on individual states and changes they have implemented regarding Medicaid alcohol rehab in recent years.

Medicaid Expansion

All but 12 states expanded benefits to cover all families with incomes below a certain level. For many states, you can qualify for Medicaid based on your income alone. They calculate income using MAGI and a percentage of the federal poverty level. For example, Colorado adults are eligible for Medicaid if their income is 138% of the federal poverty level. Alabama has not yet adopted alcohol rehab Medicaid expansion benefits.⁶

For states like Colorado, using the 138% of the federal poverty level requirement means that income ranges resemble the following:⁷

A family size of 1 is $21,597.
A family size of 2 is $29,187.
A family size of 3 is $36,777.
A family size of 4 is $44,367.

What is Covered in a Medicaid Alcohol Rehab?

Each state is required to provide minimum substance use disorder coverage. However, they can add to the list of coverages and inclusions if they choose. Medicaid alcohol rehab services must be a medical necessity, typically a life-saving service like inpatient treatment for alcohol toxicity.⁸

All states have the option to provide much-needed alcohol rehab services to enrollees with behavioral health issues. Often called the “rehabilitative state plan benefit” or “rehab option” for short, this program may feature any or all of the following:⁸

Therapy or counseling with licensed providers
Recovery support groups
Life skills training
Relapse prevention and early recovery skills
Employment training
Medication-assisted treatment (MAT)
Inpatient and outpatient detoxification
Partial hospitalization programs
Intensive outpatient programs
Inpatient residential programs

How Do ACA Healthcare Plans Cover Alcohol Rehab?

If you don’t meet the eligibility criteria for Medicaid, you can still obtain healthcare coverage at affordable costs, even if you have pre-existing conditions. You can choose between health management organizations (HMOs) or preferred provider organizations (PPOs). Both types of insurance offer low copayments but limit where you can receive Medicaid rehab services, especially HMOs, which are less flexible than PPOs.⁹

Insurance plans are purchased on the Health Insurance Marketplace online. The plans split costs with consumers based on the details of their agreements. Plans range from Platinum to Bronze, with Platinum covering the most significant percentage of costs, typically 90%, and Bronze at 60%. Services for Medicaid alcohol rehab vary based on state requirements.⁹

Who Qualifies for Medicare Alcohol Rehab?

Medicare is available for Americans who are 65 or older, but several factors expand eligibility to other groups, including:¹⁰

U.S. citizens
Documented immigrants living in the U.S. for at least five years
Disability recipients under 65 receiving benefits for at least two years
Medicare-covered government employees and spouses
End-stage renal disease, Lou Gehrig’s disease, or other terminal conditions
Recipient of pension disability from the Railroad Retirement Board

If you don’t qualify based on these requirements, you can buy into the program and pay affordable premiums to receive health insurance coverage. You can also purchase various Medicare add-on coverages to supplement your base plan.

You likely have questions like, “Does Medicare cover alcohol rehab?” The answers below apply to behavioral health and substance misuse treatment.

Alcohol Rehab Medicare Part A

Medicare Part A covers inpatient alcohol rehab Medicare. You must first qualify for inpatient stay by meeting both of the following:¹¹

Nursing care
Medications prescribed by a physician
Supplies and equipment needed to provide treatment services

Rehabilitation services, including psychotherapy and support groups

Medicare pays for early intervention services for substance use disorders. Recognizing and getting started early can prevent longer-term consequences of alcohol misuse.

The structured assessment and brief intervention (SBRIT) assesses you for signs of alcohol misuse before developing into a diagnosable disorder. There are three steps to this approach:¹¹

Screening and assessment provided by licensed professionals in an outpatient clinical setting to measure alcohol misuse and if it correlates with risky behaviors
Brief intervention methods help you understand how alcohol affects your life and that getting treatment now can prevent an alcohol use disorder
Referrals are given for anyone who wants to learn more on how to prevent an alcohol use disorder

Medicare Part A will pay for inpatient Medicare alcohol rehab services for up to 190 days, but only one time, at a specialty hospital. There is no limit to days for treatment at a general hospital.¹¹

Partial-hospitalization programs
Intensive outpatient programs
Individual and group therapy with licensed providers
Alcohol screenings and evaluations
Medications

Alcohol Rehab Medicare Part C

Medicare Part C is also called the Medicare Advantage Plan. You can choose to get this plan instead of the original Medicare parts A and B. It offers the same coverage as the original but can have different rules, costs, and restrictions. There are many kinds of alcohol rehab Medicare Part C plans to choose from, and you can include Medicare Part D in any of your packages.¹¹

Alcohol Rehab Medicare Part D

Medicare Part D covers prescription drugs deemed medically necessary in treating alcohol use disorders at a Medicare alcohol rehab. This includes medicine used during detox and maintenance, such as:¹¹

Acamprosate
Naltrexone
Disulfiram
Antidepressants
Antipsychotics
Anticonvulsants

Alcohol Rehab Medigap

You can purchase supplemental plans for extra coverage. Medicare Supplemental Insurance, or Medigap, covers copays, deductibles, and other expenses set by your Medicare parts A and B. It also covers medical costs during travel.¹¹

What is Not Covered in Alcohol Rehab Medicare?

Each Medicare insurance program and its supplemental contain services not covered. Before agreeing to services within a Medicare alcohol rehab program, it’s essential to know these exclusions. Otherwise, you might end up responsible for paying out-of-pocket. Services not covered include:¹²

Part A does not cover private nursing care or a private room. It may not cover some amenities like television
Part B does not cover inpatient services of any kind. It also will not pay for durable medical equipment not deemed medically necessary
Part D does not cover all medications used to treat substance use disorders.

Medicare Alcohol Rehab and Telehealth Services

With the many changes in how providers offer substance misuse treatment, Medicare policies have adapted to benefit those who have challenges in visiting a clinic or hospital. A limited number of telehealth services include the following:¹³

Individual therapy
Medication management
Screening and assessment
Diagnostic evaluation
Family therapy

To receive online care, you must prove why you need telehealth services, and it must also be recommended by a doctor or licensed professional.¹³

Home health services are available for those who cannot leave their home either or a psychological or physical condition. If leaving home creates a danger for you or someone else, you can receive home health services on an intermittent or part-time basis. Psychological nursing is an example of a home health service.¹³

Below is a brief snapshot of the highlights and lows of the original alcohol rehab Medicare program and the alcohol rehab Medicare Advantage program. Medicare consists of parts A and B, and Medicare Advantage consists of parts C and D.¹⁴

Providers: With traditional Medicare, you can see any doctor in the United States that takes Medicare. With Medicare Advantage, you must see doctors within the network plan.
Referrals: No referral is necessary with Medicare. Some Medicare Advantage plans require a referral.
Cost: You pay 20% of Part B Services in Medicare alcohol rehab and a monthly premium. With Medicare Advantage, your out-of-pocket expenses will vary, and you must pay the Part B premium and their plan’s premium.
