Healthcare expenses in general are on the rise, and the costs associated with long-term stays in inpatient settings or intensive outpatient treatment can seem like an insurmountable obstacle to care. That’s also true of addiction treatment, but understanding how rehab costs work can help you plan ahead.
This guide covers the cost of addiction treatment, including the main factors driving expenses, how insurance works for rehab affordability and how you can estimate out-of-pocket expenses before entering rehab.
What “Rehab Cost” Really Means
Rehab cost can be a confusing topic because the total expense related to addiction treatment may include multiple services that are all billed differently.
Rehab cost breakdowns may include:
- Inpatient rehab cost: Fees may include room and board and program charges. Medical services are often billed separately based on the number of sessions or treatments.
- Outpatient rehab cost: Programs may charge overarching fees, break down costs by specific treatments or use a combination of both approaches.
- Specialty or external rehab billing from other providers: In many cases, multiple providers submit bills for services. For example, if you’re in an inpatient setting and receive medical detox services and clinical therapy, bills may come from the rehab center, the doctor who oversaw medical detox and a licensed clinical therapist who provided therapy services.
The Biggest Factors that Affect Rehab Cost
How a drug or alcohol rehab facility or group of providers bills is only one rehab cost factor.
Other factors that affect rehab cost include:
- Level of care. Typically, inpatient or residential rehab costs more than outpatient formats, due to providing long-term accommodations, meals and 24/7 support in a structured setting.
- Length of stay/program length. Longer treatment programs result in more services, which can increase bills. For example, if a provider bills a set amount per therapy session and you have therapy three times a week, the total charges for a 2-month stay are higher than for a 1-month stay.
- Medical complexity and detox needs. Typically, a greater need for clinical services results in higher rehab expenses.
- Geographic location. The cost of living and the general cost of healthcare in the area where you seek addiction treatment impact costs.
- Facility type and optional amenities. Rehab costs may be higher for luxury addiction treatment centers or when optional specialty services, such as equine therapy, are present.
- Dual diagnosis services. Integrated treatment that addresses co-occurring mental health conditions, such as depression or anxiety, may increase costs, due in part to higher levels of care or additional treatment sessions.
Cost by Level of Care
According to the National Center for Drug Abuse Statistics (NCDAS), the average cost of drug rehab is $13,475. However, actual costs can vary widely depending on your needs and treatment options.
Medical Detox and Stabilization
Detox costs depend on your history of substance use and what level of monitoring you require during early rehab. NCDAS estimates that, in 2022, methadone detox for opioid use disorder cost an average of $12,183. In contrast, detox that wasn’t medication-assisted had an average cost of $2,228.
Inpatient or Residential Rehab
When you stay at a treatment location, costs include housing, 24/7 staffing and other charges that aren’t relevant to outpatient treatment. The NCDAS figures put inpatient rehab costs at approximately $50,000, compared to around $8,300 for outpatient rehab. Your treatment length has the greatest impact on overall costs, regardless of the level of care.
For example, using a hypothetical inpatient treatment cost of $1,500 a day:
- 30-day rehab would cost $45,000
- 60-day rehab would cost $90,000
- 90-day rehab would cost $135,000
Partial Hospitalization Programs (PHP) and Intensive Outpatient Programs (IOP)
PHP costs are often tied to hours per week. A program that requires you to attend 5 hours per day every weekday may cost more than one that requires 3 hours per day. Both PHP and IOP costs may not be all-inclusive, so it’s important to ask what’s included in the outpatient program cost and what other providers may be billing.
Standard Outpatient Counseling
Therapy costs typically depend on the type of provider you see and how often you attend therapy sessions. Group therapy typically costs less than individual therapy.
Outpatient addiction treatment may also include medication management, follow-up with doctors and general addiction counseling. Many of these include fees, although community support systems may help you find free addiction counseling.
Insurance and Rehab Costs
The average figures cited so far in this guide refer to the total cost of addiction treatment. Rehab insurance coverage can significantly impact how much you pay out of your own pocket toward those costs.
First, you’ll have to find out whether your insurance covers rehab. Plans purchased through the healthcare marketplace, sponsored by employers or provided as a government benefit typically include some level of addiction treatment coverage.
How much insurance will pay depends on factors such as whether your provider is in-network, what your deductible is and how much you’ve paid toward covered medical expenses during the year.
Insurance Terms that Change What You Pay
| Term | What It Means | How It Impacts Rehab Cost | What to Ask Your Insurer |
|---|---|---|---|
| Deductible | The amount of covered charges you must pay before your insurance begins covering services | You’ll be responsible for that part of rehab costs. For example, if your deductible is $5,000 and you’ve only met $1,000, you’re responsible for the first $4,000 of covered charges. |
|
| Co-pay | A flat amount you pay for specific types of services | You may need to pay this amount at the time of service, particularly for standard outpatient services. For example, you might need to pay $20 at each therapy appointment if your co-pay for that type of service is $20. |
|
| Coinsurance | A percentage of covered charges you’re responsible for paying, such as 20% | You may be billed for part of the rehab costs even after meeting your deductible. |
|
| Out-of-pocket max | The total amount of covered charges you may pay in a calendar year, across all insurance claims | Once you meet your out-of-pocket maximum, your insurance company typically pays claims with no co-pay or coinsurance. |
|
| Prior authorization | A preapproval from your insurance provider may be required before treatment begins | It increases the likelihood that charges will be covered and paid when claims are submitted. |
|
| In-network | When a provider has contracted with your insurance company and agreed to a specific fee schedule | Total costs are typically lower, and your share may be lower as well. |
|
| Out-of-network | Providers that haven’t contracted with an insurance company aren’t in-network | Your share of costs may be higher. In some cases, insurance companies may not cover out-of-network services at all. |
|
| Medical necessity | A reason that treatment is medically necessary, typically backed up by clinical documentation | This may help support a pre-auth or increase the likelihood that insurance will pay for rehab. |

How to Estimate Your Out-of-Pocket Rehab Cost Step by Step
Follow these steps to verify your insurance and estimate your out-of-pocket costs:
- Determine what level of care you need: Contact a rehab center and discuss your needs. Find out whether they recommend inpatient or outpatient care, and ask if medical detox and dual-diagnosis treatment are relevant.
- Confirm the network status of relevant providers. During insurance verification, find out if your rehab of choice is in-network. Ask about labs, physicians and other providers who may bill separately.
- Ask whether you need a preauthorization. Find out if you need a pre-auth and what document is required. You may need to see a healthcare provider to obtain that information, which could result in upfront costs.
- Find out about deductible, coinsurance and out-of-pocket maximum details. Get as much information as you can about what part of the costs your insurance company will consider your responsibility.
- Ask a potential rehab provider to estimate costs based on these details. Get this in writing if you can.
Keep in mind that these details can change, and rehab centers can only provide informational estimates. Ask about what could change that amount, such as additional services or extended stays.
Common Hidden Costs and Surprise-Bill Risks
Hidden rehab costs occur when you’re surprised by billed amounts. Some common surprise bills related to rehab include:
- Separate bills for physicians, labs or off-site services
- Add-on services that weren’t included in program fees
- Costs associated with prescriptions, transportation or aftercare
- Deposits for private-pay programs
- Services your insurance doesn’t cover at all, which are typically considered private-pay
To avoid surprises when bills start to come in, ask for itemized estimates that show what services are included, what is and isn’t covered by insurance and which providers are billing.
Options If You Can’t Afford Rehab
Cost should never be a reason to avoid addiction treatment. If you’re worried about the financial burden of rehab, bring that up as a concern during your first talk with a rehab center. Providers can often help you find affordable rehab options or ways to pay for rehab without insurance.
Common options include:
- Applying for Medicaid, Medicare and other programs if you’re eligible
- Seeking grants or rehab scholarships through state and local funding programs
- Asking about sliding-scale rehab fees
- Setting up payment plans
- Choosing outpatient levels of care to reduce expenses if this path is clinically appropriate
Questions to Ask a Rehab Center About Cost Before You Enroll
When talking to a potential addiction services provider, verify rehab costs by asking questions such as:
- Do you accept my insurance? If so, are you in-network with my plan?
- How much do you bill and how? What services are included in those charges?
- Will other providers bill for services they provide, and who are they?
- Do you handle prior authorization and medical reviews?
- What happens if insurance denies claims or denies service authorization midway through treatment?
- Do you offer payment plans or other financial assistance programs to help me pay my share of the costs?
Choosing a Program that’s Worth the Cost
Ensuring you work with a high-quality rehab program that prioritizes safety can help you or a loved one get greater rehab value.
Tips for finding a rehab center that’s worth the cost include:
- Looking for accreditation and state licensing to ensure the program is legitimate
- Asking what type of evidence-based care the rehab uses
- Asking about staffing ratios, as programs with high patient-to-staff ratios may not be able to support you as fully as programs with lower ratios
- Choosing programs that focus on strong discharge planning to ensure you’re supported with ongoing care coordination as you step down from more intensive treatment
- Ensuring a provider is transparent about costs and other policies
Building a Financial Plan that Doesn’t Delay Treatment
Don’t let the need to pay for rehab stop you from taking steps toward a healthier life. Start small instead. Focus on finding out what level of care may be right for you, especially since that can significantly change cost considerations.
Next, go through the process of obtaining insurance verification and understanding your potential out-of-pocket costs. Most rehab providers offer insurance verification and are happy to help with this step. Work with your chosen rehab to build a backup plan in case of denials, and understand what costs may look like as you continue your recovery journey into aftercare.
