Rehab Insurance & Cost Guide

How much does rehab cost, and will your insurance cover it? This guide explains addiction treatment costs by level of care, how private insurance, Medicaid, and Medicare work, how to verify your benefits, and what to ask before you admit, including at cannabis-friendly rehabs.

Quick answer

Rehab costs depend mostly on level of care and length of stay: outpatient is the most affordable, while detox and residential cost the most. Most private plans, Marketplace plans, Medicaid, and Medicare cover some substance use treatment. With insurance, you typically pay your deductible and copays or coinsurance up to your out-of-pocket maximum. A facility's cannabis policy does not change your coverage.

What Does Rehab Cost by Level of Care?

The biggest factor in the cost of addiction treatment is the level of care you need. Here is how each level typically compares. Select a level to browse facilities that offer it.

Medical Detox

The shortest and most medically intensive phase, typically 3 to 10 days. Because detox includes 24/7 medical monitoring, the daily rate is usually the highest of any level of care, but the total stay is short. Detox is the first step toward your ongoing level of care.

Residential / Inpatient Treatment

You live on-site with round-the-clock support. Costs vary significantly by program length (commonly 30, 60, or 90+ days), location, staffing, and amenities. Residential is generally the most expensive level of care overall.

Partial Hospitalization (PHP)

Structured treatment most of the day, five or more days a week, while you sleep at home or in sober living. PHP typically costs less than residential because housing is not included.

Intensive Outpatient (IOP)

Several hours of therapy a few days per week. IOP is a common step down from PHP or residential and usually costs less, since sessions are fewer and shorter.

Outpatient

Typically the most affordable option, with weekly sessions and flexible scheduling so you can keep working or attending school.

Medication-Assisted Treatment (MAT)

Combines FDA-approved medications with counseling, most often for opioid or alcohol use disorders. Costs depend on the medication, visit frequency, and whether it is paired with another level of care. Many plans cover MAT.

Sober Living

Supportive housing billed monthly and usually separate from clinical treatment. Insurance generally does not cover sober living rent, so rates vary by location, amenities, and house rules.

Costs vary significantly by location, program, and length of stay. Contact a facility's admissions team for specific pricing, or compare rehabs in your state.

What Affects the Cost of Treatment?

Two people at the same facility can pay very different amounts. These factors have the biggest impact on your final bill:

  • Level of care and how long you stay
  • Location and state (costs vary by region)
  • In-network vs. out-of-network status with your insurer
  • Your deductible, copays, coinsurance, and out-of-pocket maximum
  • Medical services such as detox monitoring, psychiatry, or medication
  • Treatment for co-occurring mental health conditions
  • Private rooms, amenities, and specialty programming

Treating a dual diagnosis (substance use plus a mental health condition) together is often more effective and may be covered as a single program. Browse all conditions treated.

How Insurance Covers Addiction Treatment

  • Most major insurance plans include behavioral health and substance use disorder coverage.
  • Coverage depends on your plan, diagnosis, medical necessity, and level of care.
  • Federal parity law (MHPAEA) requires many plans to cover mental health and substance use care on terms no more restrictive than medical and surgical care.
  • In-network facilities usually cost you less. Out-of-network benefits may be available on PPO plans.
  • Insurers often approve treatment in stages and review progress to continue coverage.

Key terms to know: your deductible is what you pay before coverage starts, a copay or coinsurance is your share of each service, and the out-of-pocket maximum is the most you will pay in a plan year for covered in-network care.

Private Insurance, Medicaid, and Medicare

Private and employer insurance

Most commercial plans (PPO, HMO, EPO, POS) include behavioral health and substance use coverage. PPO plans often include out-of-network benefits, while HMO and EPO plans usually require in-network providers and may require a referral or pre-authorization.

ACA Marketplace plans

Plans sold on the Health Insurance Marketplace must cover mental health and substance use disorder services as one of the essential health benefits. Coverage details, networks, and cost-sharing still vary by plan.

Medicaid

Medicaid covers substance use treatment in every state, though which services are covered and which facilities accept it varies by state. Many facilities do not accept Medicaid, so confirm before admission.

Medicare

Medicare can cover inpatient and outpatient substance use treatment when it is medically necessary and provided by a Medicare-approved provider. Part A generally covers inpatient care, Part B outpatient services, and Part D prescription medications.

TRICARE and VA benefits

Active-duty service members, veterans, and their families may be covered through TRICARE or VA health care. Coverage and approved facilities depend on eligibility and plan.

How to Verify Your Insurance Benefits

Verifying benefits before admission prevents surprise bills. The easiest way is to call the facility you want to attend. Their admissions team will check your coverage with your insurer for you, so you don't have to call your insurance company yourself.

  1. Pick the facility you want to attend and find its admissions phone number on its listing.
  2. Have your insurance card ready: the policyholder's name and date of birth, member ID, and group number.
  3. Call the admissions team and share your insurance information. Most facilities run a free, confidential benefits check and tell you whether they accept your plan.
  4. Ask them what your plan covers for the level of care you need, whether they are in-network, and whether pre-authorization is required. Most facilities will handle it for you.
  5. Ask for your estimated out-of-pocket costs, including your deductible, copay or coinsurance, and out-of-pocket maximum.

Does Cannabis Policy Affect Coverage?

No. A facility's cannabis policy is a clinical approach, not a billing category. Insurance covers the treatment program based on your diagnosis, medical necessity, and level of care, so a cannabis-friendly program is billed the same way as a traditional recovery program.

Medical cannabis itself is generally not covered by insurance and, when part of a patient's care, is managed separately from the treatment program. Learn what each policy means in our Cannabis Policy Guide, or follow our step-by-step guide on how to find a cannabis-friendly rehab.

Common Ways to Pay for Treatment

  • Private insurance (PPO, HMO, EPO, POS)
  • Out-of-network benefits
  • Medicaid or Medicare (at facilities that accept them)
  • Self-pay / private pay
  • Payment plans or healthcare financing
  • Sliding scale fees or financial assistance offered by some facilities
  • Employee assistance programs (EAP)
  • State-funded or grant-funded treatment programs

Ask the facility's admissions team which payment options they accept. Many list accepted insurance on their GreenRehabs profile, which you can find through the treatment center search.

Questions to Ask a Facility's Admissions Team

  1. Do you accept my insurance plan?
  2. Are you in-network or out-of-network with my provider?
  3. Will you verify my benefits before admission, and is there a fee for that?
  4. Is pre-authorization required, and will you handle it?
  5. What will my estimated out-of-pocket costs be?
  6. What's included in the cost of the program (medications, labs, therapy, housing)?
  7. Are there additional costs I should know about?
  8. Do you offer payment plans or financial assistance?
  9. What happens if my insurance stops covering my stay?

Be cautious of facilities that pressure you to pay upfront before verifying benefits or offer free travel or housing in exchange for your insurance.
