Drug rehab: how it works, what it costs, and how to choose

Clinicians place people on a continuum defined by the ASAM Criteria — the standard insurers also use to decide what they will cover. Higher is not automatically better: the goal is the least intensive level that is safe and effective for you.

Withdrawal management (detox) makes it physically safe to stop using. It does not treat the disorder. NIDA is explicit that detoxification alone does little to change long-term drug use, and that people who leave after detox without continuing care relapse at high rates.

The practical rule: never accept a program that offers detox with no clear plan for what comes next. Ask, before admission, what the step-down looks like and who arranges it.

The honest answer is that "30/60/90 days" describes a residential stay, not a course of treatment. Research summarized by NIDA repeatedly finds that remaining in treatment for an adequate period — generally around 90 days or more across all levels combined — is critical, and that people who leave early have markedly worse outcomes.

In practice that often looks like: a week of detox, three to six weeks residential, several months of IOP or outpatient, and ongoing medication or support after that. Insurance authorizes each stage on medical necessity and reviews it as you go, so days are extended when the clinical team documents continued need.

Coverage is not the question; the terms are. Under the Affordable Care Act, substance use treatment is an essential health benefit, and the federal parity law requires plans to cover it no more restrictively than medical care — the same deductibles, the same limits, the same authorization rules.

What actually sets your bill: your plan type (PPO plans cover out-of-network centers; HMO and EPO plans generally do not), whether the program is in-network, and where you stand on your deductible and out-of-pocket maximum. Detox and residential care almost always require prior authorization. A free benefits check answers all of this in minutes — see our insurance coverage guides for your specific insurer.

For opioid use disorder, the FDA has approved three medications — buprenorphine, methadone, and naltrexone — and all three are demonstrated safe and effective. Combined with counseling, medication is the standard of care, not a shortcut or a substitute addiction. For alcohol use disorder, naltrexone and acamprosate are similarly evidence-based.

A program that refuses medication on principle is applying ideology, not medicine. If medication is clinically indicated for you, that refusal is a reason to look elsewhere — and insurers cover these medications, per SAMHSA.

Marketing pages all look the same. These questions separate real programs from expensive ones.

Admission starts with an assessment — medical history, substance use history, mental health, and a physical. If withdrawal is a risk, medical detox begins immediately with monitoring and, where appropriate, medication to make it safe and tolerable. You will meet a clinician who builds the initial treatment plan, and a case manager who handles insurance authorization.

It is normal to feel worse before better in the first day or two. That is withdrawal, it is expected, and it is medically manageable — which is exactly why supervised detox exists.

If you are ready, the fastest path is a free benefits check plus a clinical assessment — both can happen the same day. If you are not sure yet, that is fine too: SAMHSA's National Helpline (1-800-662-HELP) is free, confidential, and open 24/7 in English and Spanish, and the federal locator at findtreatment.gov lists licensed programs near you. If someone is in immediate danger, call 911; for a mental-health crisis, call or text 988.
