**Here is the short version.** In Massachusetts, most health insurance covers addiction treatment: detox, short-term residential stabilization, outpatient counseling, and medication. MassHealth covers the widest range. State law also requires MassHealth and state-regulated private plans to cover detox and stabilization for up to 14 days without making you wait for approval. What insurance usually does not pay for is what surrounds treatment: rent at a sober home, most faith-based programs, and bills from programs outside your plan’s network.

**You do not need insurance to get care in this state. You do need to know which kind of plan you have, because the rules change with it.**

## What does the law require insurance to cover?

There are two layers. Federal parity law says a health plan that covers substance use treatment cannot put tighter limits on it than it puts on medical and surgical care. Plans sold to individuals and small employers must include substance use treatment as a basic benefit.

Massachusetts adds specifics. Under a 2014 state law, MassHealth and state-regulated plans must cover medically necessary detox (the state calls it acute treatment services) and clinical stabilization services for up to 14 days with no prior authorization at an in-network, state-licensed program. The plan can begin reviewing the stay on day seven, but it cannot cut off coverage before the 14 days are up.

A 2024 state law added two more protections. State-regulated plans must cover naloxone, the medication that reverses an opioid overdose, with no prior authorization and generally no copay. And plans renewed on or after January 1, 2026 must cover the services of a recovery coach who is licensed or otherwise authorized under state law, also without prior authorization. That benefit is new. Ask your plan how to find a coach it covers.

## What does MassHealth cover?

MassHealth, the state’s Medicaid program, covers more of the recovery path than most private plans. That includes detox, clinical stabilization, residential rehabilitation programs, outpatient counseling, intensive outpatient and day programs, and medications for opioid and alcohol use disorder, including methadone through licensed opioid treatment programs. It has covered recovery coaches and recovery support navigators since 2018.

The state says every MassHealth coverage type includes substance use treatment except MassHealth Limited. If you think you might qualify and are not enrolled, call MassHealth Customer Service at 800-841-2900. The Health Care For All HelpLine, 800-272-4232, is a free service that will walk you through the application.

## What do private plans cover?

It depends on who regulates the plan. A fully insured plan, the kind you buy through the Health Connector or get from many smaller employers, must follow the Massachusetts rules above. A self-funded plan, which is how many large employers provide coverage, answers to federal law instead. Parity still applies, but state mandates such as the 14-day rule and the recovery coach benefit may not.

The card in your wallet will not always tell you which one you have. Your employer’s benefits office will, and so will the member services line.

Covered also does not mean free. Deductibles, copays, and coinsurance apply to most services, and using an in-network program matters more than almost anything else. Medicare covers inpatient and outpatient substance use treatment as well, including opioid treatment programs.

## What does insurance usually not cover?

**Sober housing —** A sober home is housing, not treatment. Residents pay rent or a weekly fee themselves. This is different from a licensed residential rehabilitation program, which MassHealth does cover.

**Most faith-based programs —** A church recovery ministry or a faith-based residential program that is not a licensed treatment provider does not bill insurance. Many are free or supported by donations. Some charge a fee. Ask.

**Out-of-network programs —** This includes many out-of-state programs that advertise online. Coverage may be partial or nothing, and you can be billed the difference. Get the answer in writing before you travel.

**Coaches in private practice —** An independent recovery coach may not accept insurance at all. Ask about fees before the first session.

Mutual-aid meetings such as AA, NA, Celebrate Recovery, and church recovery groups cost nothing and involve no insurance at all.

## What should I ask when I call my insurance company?

Call the member services number on the back of your card and write down the answers to these:

**1.** Is this plan fully insured or self-funded?

**2.** Is this program in my network? Give the name of the program and the level of care.

**3.** Does this level of care need prior authorization, and who requests it?

**4.** What will I owe? Ask about the deductible, the copay or coinsurance, and how much of your out-of-pocket maximum is left.

**5.** How many days or visits are approved, and what happens when they run out?

Write down the date, the name of the person you spoke with, and a reference number for the call. A treatment program’s admissions office will usually check your benefits for you at no charge. Let them.

*If the levels of care are unfamiliar, we mapped them in “[Detox, Inpatient, IOP, Outpatient: A Plain-English Map.](https://marktwelverecovery.org/articles/detox-inpatient-iop-outpatient-a-plain-english-map)”*

## What if I have no insurance?

You can still get treatment. The Massachusetts Substance Use Helpline, 800-327-5050, can find programs that take people without coverage. The state’s Bureau of Substance Addiction Services (BSAS) funds treatment for residents who have no other way to pay. Community behavioral health centers provide crisis services regardless of insurance. An emergency room must, under federal law, screen and stabilize anyone who walks in, insured or not.

Then apply for MassHealth. Many people qualify and do not know it. Our guide to “Recovery Resources in North Central Massachusetts” lists where to start locally.

## What if my plan says no?

A denial is not the last word. Ask for it in writing, with the reason. Then file an internal appeal with the plan. Your provider can help, and you can ask for an expedited review if waiting would put your health at risk.

If a fully insured plan still says the care is not medically necessary, you have four months to ask the state’s Office of Patient Protection for an external review by an independent clinician. The decision is binding on the insurer. The state reports that more than 40 percent of these reviews are decided in the patient’s favor. Self-funded plans run their own external review, and MassHealth has its own appeal process.

## What can a family or a church do?

Make the calls. Someone in the first days of withdrawal is rarely in any shape to sit on hold. With that person’s permission, a spouse, a parent, or a trusted friend from church can do most of the insurance legwork.

Paul told the Galatians to “bear one another’s burdens” (Galatians 6:2). Sometimes that looks like forty minutes on hold and a notebook full of reference numbers. Jesus asked who would start building a tower without first sitting down to count the cost (Luke 14:28). Counting the cost is not a lack of faith. It is part of finishing.
