What 'Medically Necessary' Actually Means in an Insurance Denial
The phrase "not medically necessary" sounds objective. It is not. It is a contested technical standard — and under the 2024 federal parity r...
Understand before you decide
Addiction treatment has more variation than the industry admits. Start by understanding what you are choosing between.
Not every program is a fit for every situation. This site is an orientation — to what treatment actually looks like, what it costs, and what questions to ask before admission.

Core concepts
The four things that actually determine what happens next.
Most published guidance skips the mechanics. These four are the ones that shape outcomes in practice — and the ones that most families learn about the hard way.
Start here
Level of care
Six clinically distinct levels — from outpatient through medically managed inpatient. The right one depends on withdrawal risk, co-occurring conditions, and home stability. Matching it is a clinical judgment, not a sales pitch.
Full guide to the six levelsMAT availability
For opioid use disorder, medication-assisted treatment cuts mortality by roughly half. Programs that refuse to allow it are working outside the current evidence base. Ask explicitly.
Insurance reality
Under the 2024 federal parity rule, every major insurer must cover medically necessary substance-use treatment at parity with medical care. In practice: deductibles, in-network lists, and prior-auth hurdles still matter — and now they are auditable.
Aftercare, not admission
Most relapse happens in the 90 days after discharge. The strength of the aftercare plan is the single best predictor of whether the work holds. Ask about it before admission, not during discharge planning.
Six levels of care
What the options actually look like.
ASAM defines six distinct levels. The right fit depends on withdrawal risk and home stability — not on severity alone.
Medical Detox
Medically supervised withdrawal. 5–7 days. Required first step for severe dependence.
Residential
24/7 clinical care in a facility. Typical 30 days. For severe cases or unstable home environments.
Partial Hospitalization
Daytime clinical care, evenings home. ~20 days. Step-down from residential.
Intensive Outpatient
9–12 hrs/week, life continues around treatment. 8–12 weeks. The most accessible level.
MAT (Medication-Assisted)
Buprenorphine / naltrexone / methadone for OUD or AUD. Cuts mortality ~50%. Ask every program.
Aftercare
Structured post-discharge support. 90-day window is where most relapse happens. Plan before admission.
Costs
What treatment actually costs (before insurance).
Sticker prices are wider than most families expect. The same 30-day residential stay can list at $15,000 or $38,000. Here is the range, by level of care.
| Level of care | Duration | Sticker range | With commercial insurance (typical) |
|---|---|---|---|
| Medical detox | 5–7 days | $4,000 – $12,000 | Deductible + 20–30% coinsurance |
| Residential | 30 days | $15,000 – $38,000 | Deductible + coinsurance to OOP max |
| Partial hospitalization | 20 days | $7,000 – $18,000 | Deductible + 20–30% coinsurance |
| Intensive outpatient | 8–12 weeks | $3,500 – $9,000 | Often the most accessible level |
| MAT (buprenorphine) | Long-term | $1,500 – $4,000 / year | Typically Tier 1/2 generic |
The thing nobody told me was that the first question is not 'which rehab' — it is 'which level of care.' Understanding that one distinction changed everything. Our daughter didn't need residential. She needed IOP with good aftercare, and we found it because we knew to ask.

The Six Levels of Addiction Care, Explained for People Who Do Not Already Know
Most people searching for rehab do not know there are six distinct levels of care, each appropriate for different clinical situations. This...
Questions people actually ask
The questions families ask in the first week.
Answered from the same sources we use on the rest of the site: SAMHSA, NIDA, CMS, ASAM, peer-reviewed research.
Where should I start if I have never looked at treatment options before?
Three questions first, before browsing any specific program. (1) Is this an emergency — active withdrawal, overdose risk, suicidal thinking? If yes, call 911 or 988 now, not a rehab. (2) Is there a primary-care doctor or therapist already involved? They are the right first call for a clinical recommendation. (3) If neither applies, start by reading the level-of-care page on this site — it maps the six clinically distinct options. Then use the state directory to filter verified programs. Avoid "best rehab" listicles and sponsored ads during the first hour.
How do I know the information on this site is reliable?
Every facility record comes from SAMHSA's public Behavioral Health Treatment Services Locator — the same source 211 and hospital case managers use. Editorial content cites peer-reviewed research (NEJM, JSAT, Addiction journal) and federal agency publications (SAMHSA, NIDA, CMS, ASAM) inline. Pages are dated with "last verified" timestamps and reviewed quarterly. Full sourcing and correction policy: editorial methodology.
What questions should I ask any program before I commit?
Six questions, in this order. (1) What level of care do you recommend for my situation, and on what evidence? (2) Do you allow MAT (buprenorphine/methadone/naltrexone) if I need it? (3) Are you in-network with my insurance? If not, what is the cash price? (4) What does your aftercare plan specifically include — the name of the outpatient program, not just "we help you find one"? (5) Are you Joint Commission or CARF accredited, and what is your state license number? (6) Can I talk to a clinician before admission, not just an admissions rep?
How does this site make money — is it an affiliate?
Transparent answer: when a reader calls the helpline on this site and ultimately enters an in-network treatment program, we may receive a placement fee from that facility — the same model most treatment-information sites run on. Two things we commit to anyway. (1) Facility order in our directory is not bought — it reflects SAMHSA data and state license status, not who pays us. (2) Before we send you anywhere else, we send you to public resources: SAMHSA's FindTreatment.gov, 211, and the 988 Crisis Lifeline.
