How Much Does Rehab and Addiction Treatment Cost?

It depends on the level of care. Standard outpatient counseling runs about $100 to $300 per session, medication-assisted treatment (MAT) about $100 to $500 per month, intensive outpatient (IOP) and partial hospitalization (day) programs about $250 to $1,000 per day, medical detox about $1,000 to $1,500 per day for a 3 to 7 day stay, and a 30-day residential (inpatient) program commonly $15,000 to $60,000 or more. With insurance, your share is limited by your copays, coinsurance, and yearly out-of-pocket maximum.

Medically supervised detox is commonly billed about $1,000 to $1,500 per day, so a typical 3 to 7 day stay runs roughly $5,000 to $15,000. Outpatient detox costs less. Detox is a medical service, and when it is medically necessary most plans cover it under mental health parity law; your share is your normal cost sharing up to your out-of-pocket maximum.

The federal Mental Health Parity and Addiction Equity Act (MHPAEA) requires most plans to cover substance use disorder treatment no more restrictively than medical and surgical care, and the Affordable Care Act makes it an essential health benefit on individual and small-group plans. That does not mean claims are never denied, but a denial of medically necessary care, or one that treats addiction care worse than comparable medical care, can and should be appealed.

This is the most common fight. Insurers frequently approve fewer days than the treatment team recommends, or deny residential in favor of a lower level of care such as IOP. Under parity law and the ASAM Criteria for level of care, these decisions can be appealed, and a peer-to-peer review or external appeal backed by the clinician's documentation often extends coverage. Do not accept a first denial as final.

Often, yes. Medicaid is the largest payer for addiction treatment and covers it in every state for those who qualify. SAMHSA block grants fund free or low-cost state and community programs for people who are uninsured or low-income, and you can search them at FindTreatment.gov or call 1-800-662-HELP. Many employers offer an Employee Assistance Program (EAP) that covers assessment and short-term counseling at no cost and confidentially. The SAMHSA National Helpline can point you to options in your area.

Use in-network programs where possible, ask the treatment center's billing team about a single-case agreement when no in-network option offers the level of care needed, and confirm the level of care is authorized before admission. Check whether Medicaid, a state-funded program, or your employer's EAP applies. Appeal denials of medically necessary care under parity law. If you already have a large bill or a denial, have it reviewed. CareRoute Bill Defense reviews and negotiates these bills with no fee unless we save you money.
