Alcohol Rehab Cost: 28-Day, Annual, and Full-Episode Pricing

Alcohol rehab costs $15,000–$45,000 for a 30-day inpatient program without insurance, or $5,000–$18,000 out-of-pocket with PPO insurance. Medical detox adds $2,000–$10,000 because alcohol withdrawal can be fatal and requires 24/7 CIWA-Ar-guided benzodiazepine protocols. A full year of structured treatment — detox, inpatient, PHP, IOP, and MAT — averages $25,000–$70,000 self-pay or $8,000–$25,000 out-of-pocket with insurance.

Level of Care	Duration	Without Insurance	With PPO
Medical detox (alcohol)	5–10 days	$2,000 – $10,000	$800 – $4,000
Inpatient residential	30 days	$15,000 – $45,000	$5,000 – $18,000
Inpatient residential	60 days	$28,000 – $80,000	$8,000 – $30,000
Inpatient residential	90 days	$42,000 – $120,000	$12,000 – $42,000
Partial hospitalization (PHP)	4–6 weeks	$6,000 – $18,000	$2,000 – $7,500
Intensive outpatient (IOP)	8–12 weeks	$3,000 – $8,000	$1,000 – $3,500
MAT (naltrexone or Vivitrol, monthly)	Ongoing	$200 – $1,500	$25 – $250

Alcohol use disorder is the most common substance use disorder in the U.S. — NIAAA reports 28.9 million adults met diagnostic criteria in 2023, yet fewer than 8% received any formal treatment. The single biggest barrier most families report is cost uncertainty. This guide answers the four questions people search most — how much to treat an alcoholic, how long is the stay, how much per year, how much for 28 days — and walks through the CIWA-Ar detox protocol, the 4-medication MAT decision tree, and the 2026 insurance math.

How Much Does It Cost to Treat an Alcoholic? (The Full Episode)

Most cost guides stop at the 30-day inpatient number. That number is the entry point, not the full episode. A clinically complete alcohol-use-disorder treatment episode stretches across 4–5 months of structured care plus year-one MAT.

Phase	Duration	Self-Pay	PPO Out-of-Pocket
Medical detox	5–10 days	$2,000 – $10,000	$800 – $4,000
Inpatient residential	21–25 days (within 30-day cycle)	$13,000 – $35,000	Continues toward OOP max
Partial hospitalization (PHP)	4–6 weeks	$6,000 – $18,000	Capped by OOP max
Intensive outpatient (IOP)	8–12 weeks	$3,000 – $8,000	Capped by OOP max
MAT year 1 (naltrexone or acamprosate)	12 months	$400 – $1,500	$120 – $900
Standard outpatient / aftercare year 1	Ongoing	$1,000 – $4,000	$300 – $900
Full-episode total	4–5 months + year 1	$25,000 – $76,500	$7,000 – $9,500 OOP max

The PPO insight: Once your deductible and coinsurance add up to your annual out-of-pocket maximum ($7,000–$9,500 for individual plans in 2026, $18,900 for family), the insurer pays 100% for the rest of the plan year. Most insured alcohol-treatment patients hit their OOP max inside the first 7–14 days of inpatient care, which means PHP, IOP, MAT, and outpatient therapy through the end of the calendar year are effectively free.

For the underlying insurance math, see how much does rehab cost and does insurance cover rehab.

How Long Is the Average Alcohol Rehab Stay?

Average inpatient stay: 28–30 days. This is the industry-standard insurance billing cycle, not a clinical recommendation.

Clinically recommended total: 90+ days of structured care across the continuum.

The gap between these two numbers exists because most insurers authorize residential care in 5–14 day blocks with concurrent review, while NIDA and NIAAA research consistently shows better 12-month outcomes with longer total treatment time. The evidence-based sequence:

Phase	Duration	What Happens
Medical detox	5–10 days	CIWA-Ar assessment every 4 hours, benzodiazepine taper, thiamine, medical stabilization
Inpatient residential	21–25 days	Individual + group therapy, initiation of MAT, family sessions, relapse prevention
Partial hospitalization (PHP)	4–6 weeks	30–40 hours/week clinical programming, return home each evening
Intensive outpatient (IOP)	8–12 weeks	9–15 hours/week, return to work with modified schedule
Standard outpatient + MAT	12+ months	Weekly therapy, monthly MAT management, aftercare

NIDA recommendation: The minimum 90 days is typically achieved by stacking inpatient + PHP + IOP, not by remaining at the most intensive level the entire time. Stacking is also more insurance-friendly — insurers readily authorize step-down even when they push back on extended inpatient.

For the step-down logic, see types of rehab programs, 30-day, 60-day, and 90-day programs.

How Much Does Alcohol Rehab Cost Per Year?

No top-ranking cost page directly answers this, but it’s the most practical question for families planning a full recovery year. The annual cost breaks into three tiers.

Year One (Full Treatment Year)

Detox + inpatient + step-down + MAT + aftercare.

• Self-pay: $25,000 – $70,000
• PPO with insurance: Capped at OOP max — typically $7,000 – $9,500
• HMO with insurance: $5,000 – $15,000 OOP
• Medicaid: $0 – $500

Year Two (Maintenance Year)

MAT continuation + standard outpatient therapy + possible sober living.

• MAT (oral naltrexone or acamprosate): $400 – $1,500 self-pay; $120 – $500 insured
• Standard outpatient (monthly–biweekly): $1,200 – $6,000 self-pay; $300 – $1,200 insured
• Sober living (if used): $6,000 – $30,000 (most plans don’t cover)

Year two without sober living: $1,600 – $7,500 self-pay; $420 – $1,700 insured.

Year Three and Beyond

Most people continue MAT plus less-frequent outpatient check-ins.

• Annual cost: $500 – $3,000 self-pay; $100 – $500 insured

One-Year Insurance Ceiling

With PPO insurance, total alcohol rehab cost in year one is bounded by your plan’s annual OOP max — it cannot exceed that number regardless of how long the treatment lasts or how expensive the facility is, as long as you stay in-network. This is why the insurance math almost always favors enrollment before paying self-pay. See how to get insurance to cover rehab.

How Much Is 28 Days of Alcohol Rehab?

The “30-day program” is almost always billed on a 28-day insurance cycle. This is the exact number most people search for.

Self-pay (in-network accredited facility): $14,000 – $42,000.

With PPO insurance, out-of-pocket:

Plan Design	Your 28-Day OOP
$2,000 deductible / 20% coinsurance / $8,700 OOP max	$5,000 – $8,700
$3,500 deductible / 30% coinsurance / $9,500 OOP max	$7,000 – $9,500
$1,500 deductible / 10% coinsurance / $7,000 OOP max	$3,000 – $7,000

Worked example: Facility bills $35,000 for 28 days. You have $2,000 deductible, 20% coinsurance, $8,700 OOP max, $0 met year-to-date.

• Deductible: $2,000
• 20% of remaining $33,000: $6,600
• Running total: $8,600 (below OOP max — that’s what you pay)

If the facility bills $55,000 instead:

• Deductible: $2,000
• 20% of remaining $53,000: $10,600
• Running total: $12,600, capped at OOP max → $8,700

Once the facility bill crosses roughly $35,500 on this plan, your out-of-pocket is capped. Staying longer or picking a more expensive program doesn’t cost you more — it costs the insurer more. See how much does rehab cost for the same math applied to all substances.

The CIWA-Ar Protocol and Why Alcohol Detox Costs More

Alcohol detox is the most clinically intensive detox after benzodiazepines. Understanding what’s inside the per-day rate explains why it costs $250–$800/day at freestanding facilities and $1,000–$3,000+/day at hospital-based units.

Withdrawal Timeline

Time Since Last Drink	Symptoms	Medical Priority
6–24 hours	Anxiety, tremor, sweating, nausea, elevated vitals	Baseline CIWA-Ar, initiate benzodiazepine protocol
24–48 hours	Peak seizure risk; symptoms intensify	Continuous monitoring, IV access, seizure precautions
48–72 hours	Peak DTs risk	1:1 monitoring if DTs develop; transfer to ICU if severe
Day 5–7	Acute resolution	Taper benzodiazepines, initiate MAT planning
Weeks 2–8	Post-acute withdrawal (PAWS)	Outpatient monitoring, sleep/mood support

The CIWA-Ar Assessment

Clinical Institute Withdrawal Assessment for Alcohol, Revised. A 10-item validated scale scored every 4 hours. Items include nausea, tremor, sweats, anxiety, agitation, tactile/auditory/visual disturbances, headache, and orientation.

• Score 0–9: Mild withdrawal — symptom-triggered benzodiazepine dosing
• Score 10–19: Moderate withdrawal — scheduled benzodiazepine taper
• Score 20+: Severe withdrawal — consider ICU, continuous infusion, possible airway protection

What’s in the Per-Day Rate

• 24/7 RN/LPN coverage with CIWA-Ar assessments every 4 hours
• Daily physician rounds
• Benzodiazepine taper (lorazepam/Ativan or chlordiazepoxide/Librium)
• Thiamine 100 mg IV/IM daily before any glucose (prevents Wernicke-Korsakoff)
• Folate, multivitamin, magnesium repletion
• IV fluids with electrolytes
• Anti-nausea medication (ondansetron)
• Cardiac telemetry if indicated
• Psychiatric consultation if mood/suicidality concerns
• Seizure precautions

When Hospital-Based Detox Is Required

Freestanding detox is sufficient for most patients. Hospital-based detox is clinically required when:

• History of seizures or DTs
• Cardiac arrhythmia or severe hypertension
• Liver failure or pancreatitis
• Active suicidal ideation or psychosis
• Pregnancy
• CIWA-Ar persistently above 20

Hospital detox adds $500–$2,000 per day but is covered under your plan’s inpatient hospital benefit. See medical detox cost for the full hospital-vs-freestanding breakdown.

Which MAT Medication? (The 4-Approach Decision Tree)

Three FDA-approved medications plus one evidence-based dosing protocol. Most cost pages list them; few help you choose.

Naltrexone (Daily Oral or Monthly Vivitrol)

Mechanism: Opioid-receptor antagonist. Reduces alcohol cravings and blunts the pleasurable reward from drinking.

Best for: People who want to reduce drinking or maintain abstinence with ongoing temptation. Also used for the Sinclair Method (see below).

Form: 50 mg oral tablet (ReVia) daily, or 380 mg intramuscular injection (Vivitrol) monthly.

Cost:

• Generic oral: $30–$80/month self-pay; $10–$75 insured
• Vivitrol injection: $1,200–$1,500/month self-pay; $25–$250 insured

Acamprosate (Campral)

Mechanism: Modulates glutamate/GABA neurotransmission disrupted by chronic alcohol use. Helps the post-detox brain re-stabilize.

Best for: People who have stopped drinking and want to stay stopped. Most effective when initiated after 5–7 days of abstinence.

Form: 333 mg tablets, two tablets three times daily (1,998 mg total).

Cost: $150–$400/month self-pay; $10–$60 insured.

Disulfiram (Antabuse)

Mechanism: Blocks aldehyde dehydrogenase. Drinking alcohol while on disulfiram produces flushing, nausea, vomiting, headache, hypotension — a physically aversive reaction.

Best for: Highly motivated patients, especially with supervised dosing (spouse, clinic, court-ordered monitoring). Not a craving reducer — a deterrent.

Form: 250–500 mg tablet daily.

Cost: $30–$90/month self-pay; under $20 insured.

The Sinclair Method (Targeted Naltrexone)

Mechanism: Naltrexone taken only 1 hour before drinking (not daily). Over months, pharmacological extinction reduces the drive to drink.

Evidence: European studies since the 2000s show ~78% of compliant patients achieve reduced drinking or abstinence over 12–18 months. Still underused in U.S. clinical practice as of 2026 — which is why most cost guides omit it.

Best for: People unwilling to commit to abstinence upfront but open to cutting back.

Cost: Same as oral naltrexone — $30–$80/month self-pay, $10–$75 insured, but used more sparingly (only before drinking occasions).

Combination Therapy

The 2006 COMBINE study found that naltrexone + medical management and acamprosate + behavioral therapy both outperformed single agents for most outcomes. Many clinicians now prescribe naltrexone + acamprosate together for patients who can tolerate both.

Insurance note: MHPAEA prohibits insurers from applying more restrictive coverage to addiction medications than to comparable medications for other chronic conditions. All four approaches should be on formulary.

Alcohol Use Disorder in 2026: The Data

• 28.9 million adults had alcohol use disorder in 2023 per NIAAA/NSDUH — 11.2% of the U.S. adult population
• ~178,000 deaths/year attributable to excessive alcohol use (2020–2021 CDC data); fourth leading preventable cause of death in the U.S.
• Fewer than 8% of adults with AUD receive any formal treatment in a given year — the largest treatment gap of any SUD
• 1%–5% mortality from untreated severe alcohol withdrawal (NEJM reviews)
• $249 billion/year economic cost of excessive alcohol use per CDC — lost productivity, healthcare, criminal justice, motor vehicle crashes

These numbers are why 28.9 million people qualify for treatment but only a small fraction enter it. Cost transparency is the lever that closes the gap.

The Cost of Untreated Alcohol Use Disorder

Untreated AUD costs far more over time than any treatment episode. Typical annual spend for a person in moderate-to-severe AUD:

Category	Annual Range
Alcohol purchases ($20–$100/day)	$7,000 – $36,000
Lost wages (partial/full, 3–6 months impact)	$10,000 – $40,000
Emergency department visits (1–3/year × $1,500–$3,000)	$1,500 – $9,000
Hospitalizations (pancreatitis, liver failure, DTs)	$10,000 – $80,000
Legal costs (DUI typical ~$10,000–$25,000 all-in)	$0 – $25,000
Healthcare for related conditions	$3,000 – $20,000
Conservative annual total	$31,500 – $210,000

Compare to a PPO-insured full treatment year capped at $7,000–$9,500 OOP. The insurance-aware math almost always favors treatment.

Does Insurance Cover Alcohol Rehab?

Yes. Under ACA and MHPAEA, alcohol use disorder is an essential health benefit. See does insurance cover rehab for the federal-law specifics. Quick summary by plan type:

Plan Type	Network	Typical 30-Day OOP	Notes
PPO	Broad	$6,000 – $22,000 (capped at OOP max)	Best flexibility
HMO	Narrower	$5,000 – $17,000	Referral often needed
EPO	Broad	$5,500 – $18,000	No referral; no OON
Medicaid	In-network	$0 – $500	Comprehensive
Medicare Advantage	Varies	$2,000 – $12,000	Part A + Part D

Questions to Ask Before Admission

1. Is the facility in-network for my plan?
2. What is my deductible, and what’s met year-to-date?
3. What is my coinsurance percentage for inpatient SUD?
4. What is my out-of-pocket maximum, and what’s met?
5. Is prior authorization required, and what’s the timeline?
6. How many days will be initially authorized?
7. Is Vivitrol covered under pharmacy or medical benefit?
8. If out-of-network, can a single-case agreement be pursued?

Most facilities complete a free benefits verification on your behalf. Always get the rep’s name, reference number, and written summary.

If You Don’t Have Insurance

If you’re currently uninsured, enrollment in an ACA-compliant plan almost always costs less than self-paying for treatment. Marketplace plans with broad alcohol-treatment coverage typically run $350–$700/month — less than 4 days of self-pay residential.

For full self-pay cost breakdown and financing options, see rehab cost without insurance. A licensed specialist can help identify plans that cover the specific facility and medications you need.
