Paying for alcohol treatment

Every ACA Marketplace health plan has to cover substance use disorder services, including alcohol treatment, as an essential health benefit. Medicare covers outpatient and inpatient treatment, and in 2021, 90% of Medicaid managed care plans studied covered at least one alcohol use disorder medication. Each has limits worth checking.

Coverage at a glance

Coverage	What it covers for alcohol	Watch for
ACA Marketplace plans	Mental health and substance use services as essential health benefits; pre-existing conditions covered; no spending limits	Which providers are in network depends on the plan
Large group and individual plans (parity law)	If the plan covers substance use treatment, its limits and cost-sharing can’t be stricter than for comparable medical care	Parity doesn’t force a plan to cover substance use treatment in the first place
Medicaid managed care	90.0% of plans studied covered at least one AUD medication	Only 42.7% covered all four; prior authorization common for the monthly shot
Medicare	Yearly alcohol screening and up to 4 counseling sessions (Part B); inpatient care (Part A); outpatient treatment (Part B)	Medicare.gov’s treatment page doesn’t say whether Part D covers AUD drugs
Uninsured	Sliding-fee programs at some providers	Not every program offers it; ask

Marketplace plans

HealthCare.gov says all Marketplace plans cover mental health and substance abuse services as essential health benefits. Pre-existing mental and behavioral health conditions are covered, and plans can’t set spending limits on them.

That means if you have a Marketplace plan, the question isn’t whether alcohol treatment is covered. It’s which providers are in network and what your deductible and copays are.

Parity: what it does and doesn’t require

The Mental Health Parity and Addiction Equity Act of 2008 is the law people mean when they say “parity.” It says the cost-sharing and treatment limits on mental health and substance use benefits can’t be more restrictive than the main ones that apply to medical and surgical benefits in the same category. A plan also can’t add limits that apply only to substance use treatment.

It applies to large group plans (50 or more employees) and individual coverage, and through other rules to Medicaid managed care, CHIP and Medicaid Alternative Benefit Plans.

What it doesn’t do: require a plan to offer substance use benefits at all. For non-grandfathered individual and small group plans, the ACA’s essential health benefits rule does that job. Large employer plans that cover substance use treatment have to follow parity; the law alone doesn’t make them cover it.

Amended parity rules were released on September 9, 2024. As of October 2026, the parts that rule added aren’t being enforced and a replacement is pending; the 2008 law and the 2013 rules still apply. Check the Department of Labor’s statement for the current status. If you think your plan limits alcohol treatment more tightly than comparable medical care, parity is the frame to use when you question it.

Medicaid

Medicaid coverage of AUD medication is broad but uneven.

A study by Stewart and colleagues, published in 2025, looked at 241 Medicaid managed care plans across 39 states and DC using 2021 data. It didn’t include fee-for-service Medicaid.

Medication	Share of plans covering it
Any of the four	90.0%
Naltrexone tablets	84.2%
Injectable naltrexone	72.6%
Disulfiram	63.0%
Acamprosate	54.7%
All four	42.7%

Prior authorization and quantity limits were rare, except for injectable naltrexone: 42.8% of plans that covered it used one or both. In practice, if you’re on Medicaid managed care, the naltrexone pill is the most likely to be covered without paperwork. If your prescriber wants the monthly shot, expect to check for a prior authorization step.

Medicare

Medicare has two layers here.

Screening and brief counseling

Under national coverage determination 210.8, Part B covers one alcohol misuse screening a year for adults who use alcohol but don’t meet criteria for alcohol dependence. If you screen positive, you can get up to 4 brief face-to-face counseling sessions a year in a primary care setting from a primary care clinician. You pay nothing if your provider accepts assignment.

Treatment

Part A covers inpatient hospital care, and Part B covers outpatient substance use disorder treatment services. Medicare.gov’s page on this doesn’t specifically say Part D covers alcohol use disorder medications, so check your drug plan’s formulary.

Telehealth

NIAAA notes that in many states, insurers and Medicaid now cover telehealth. If getting to an office is the barrier, ask your plan whether video visits for counseling or medication management are covered at the same cost.

If you’re uninsured or underinsured

Some programs in SAMHSA’s data report that they offer a sliding fee scale. Our state treatment pages show sliding-scale availability for each program where it’s reported. You can also use the ZIP code finder and then call a program to confirm. Sliding-scale offers change, so ask when you call.

SAMHSA’s National Helpline, 1-800-662-4357 (free, 24/7), refers callers to local treatment.

We don’t list a typical price for medication or treatment, because we haven’t found an authoritative source for one. Ask the program and the pharmacy.

Questions to ask before you start

• Is this provider in my plan’s network?
• Does my plan cover naltrexone tablets, the monthly injection, acamprosate or disulfiram, and does any of them need prior authorization?
• What’s my copay for an outpatient counseling visit, and is telehealth covered the same way?
• If I need intensive outpatient or residential care, is any approval required first?
