Rehab in Massachusetts runs anywhere from a modest copay on an in-network insurance plan to more than $20,000 a month if you pay privately for residential care. Nationally, the average cost of addiction treatment is about $13,475 per person. The number that matters, though, is not the sticker price. It’s what your specific plan leaves you to pay, and for most people with commercial insurance that figure is far smaller than the headlines suggest. Here is what each level of care costs, what insurance typically covers, and how to get an exact number for your plan today.
What Each Level of Care Costs
Addiction treatment is not one product with one price. Cost tracks the intensity of care: how much medical supervision you need, and whether you sleep at the facility. The figures below are national averages for self-pay clients without insurance, compiled by the National Center for Drug Abuse Statistics.
Typical Self-Pay Cost per 30 Days
| Level of care | Typical 30-day self-pay cost |
|---|---|
| Inpatient / Residential Rehab | $5,000 to $20,000+ |
| Medical Detox (5 to 7 days) | $1,750 to $5,600 |
| Partial Hospitalization (PHP) | $10,500 to $13,500 |
| Intensive Outpatient (IOP) | $2,000 to $8,000 / program |
| Standard Outpatient | $1,400 to $10,000 |
| Sober Living | $1,500 to $2,000 / month |
National averages without insurance (NCDAS), scale $0 to $20,000+
| Level of Care | Self-Pay Cost (National Avg.) | Typical Length | Best For |
|---|---|---|---|
| Medical detox | $250 to $800 per day | 5 to 7 days | Safely managing withdrawal from alcohol, benzos, or opioids |
| Inpatient rehab | $5,000 to $20,000+ per 30 days | 30 to 90 days | Round-the-clock structure in early recovery |
| Partial hospitalization (PHP) | $350 to $450 per day | 2 to 4 weeks | Full-day treatment while living at home or in sober living |
| Intensive outpatient (IOP) | $2,000 to $8,000 per program | 8 to 12 weeks | Structured therapy that fits around work or school |
| Standard outpatient | $1,400 to $10,000 per course | 1 to 3 months | Step-down care and ongoing relapse prevention |
| Sober living | $1,500 to $2,000 per month | 3 to 12 months | A structured, substance-free home after treatment |
| Medication-assisted treatment (MAT) | Varies by medication; methadone averages about $4,700 per year | Ongoing | Reducing cravings and relapse risk in opioid or alcohol use disorder |
What Determines How Much You’ll Pay
Two people can attend the same program and pay very different amounts. The level of care is the biggest factor. Residential treatment costs more than outpatient because it includes housing, meals, and 24-hour staffing, and plenty of people do well starting at the PHP or IOP level instead. Length of stay matters too: a 60 to 90 day inpatient program ranges from $12,000 to $60,000 self-pay nationally, though insurance is authorized in shorter increments, so few people pay for 90 days at once.
Then there is your insurance. In-network care is dramatically cheaper than out-of-network, where higher deductibles and coinsurance can apply or a claim may not be covered at all. Medical needs add cost as well. Withdrawal management with medication, psychiatric care for co-occurring conditions, and lab work raise the price, and they are also the services most likely to be covered as medically necessary. Amenities are the wild card. Luxury facilities can run $80,000 a month, but accredited clinical care does not require a luxury price tag. Outcomes come from evidence-based treatment, not ocean views.
Massachusetts Insurance Law Works in Your Favor
If you live in Massachusetts, you have stronger addiction-treatment coverage rights than residents of almost any other state. Under Chapter 258 of the Acts of 2014, commercial health plans regulated in the Commonwealth must cover medically necessary acute treatment (detox) and clinical stabilization services for up to 14 days without prior authorization. Your insurer cannot make you wait for approval before you start detox.
Massachusetts Law, Chapter 258
What this means for you: a commercial plan must cover up to 14 days of detox and stabilization with no preauthorization. The facility simply notifies your insurer within 48 hours of admission. If you need help today, coverage rules are not a reason to wait.
Federal parity law adds a second layer of protection. Insurers must cover mental health and substance use treatment at the same level as comparable medical care. Together, these rules mean a Massachusetts resident with active commercial insurance can usually start treatment within a day or two of picking up the phone.
What You’ll Actually Pay With Insurance
With an in-network provider, your real cost is not the sticker price. It’s your plan’s cost-sharing: the deductible you pay before coverage kicks in, the copays or coinsurance you owe per day or per visit, and your annual out-of-pocket maximum. That maximum is the number to watch. Once you reach it, covered treatment is paid in full for the rest of the plan year, so for many people entering a multi-week program the out-of-pocket max, not the program price, is the true worst case.
Rockland Recovery Group works with most major commercial insurance plans, including Aetna, Cigna, Humana, Optum, TRICARE, Tufts, Beacon, AllWays, and Unicare. Our admissions team confirms your exact benefits, including deductible status, copays, and covered levels of care, before you commit to anything.
Paying Without Commercial Insurance
Not everyone comes to treatment with a commercial plan, and there are still ways forward. If you are paying privately, ask the admissions team about payment plans and sliding-scale options, and ask whether a less intensive (and less expensive) level of care fits your situation clinically. The first number you are quoted is rarely the only option.
If You Have MassHealth, Medicare, or State Insurance
Rockland Recovery Group accepts most major commercial plans but does not accept MassHealth, Medicare, Medicare Advantage, or other state insurance. If that is your coverage, call us and we will help point you toward a provider who accepts it. You can also reach the free Massachusetts Substance Use Helpline at 800-327-5050 (helplinema.org), which matches residents to treatment that takes their insurance.
Weighing the Cost
These numbers are real, and so is the cost of waiting. Untreated addiction shows up as emergency room visits, lost income, legal bills, and health problems that compound year over year. Treatment is an expense with an end date. For most clients on a commercial plan, the verified cost turns out to be far lower than the figure they feared when they first searched.

If someone is unresponsive, breathing slowly, or has blue lips after using opioids, give naloxone if you have it and call 911. The Massachusetts Good Samaritan law protects people who call for help during an overdose. For a mental health crisis, call or text 988.
