Alcohol & Drug Rehabs in Littleton, Colorado

Every rehab center in the Littleton directory is a licensed or accredited provider, and listings are organized to help you compare real options rather than to promote one facility over another. We prioritize programs that hold state licensure through the Colorado Behavioral Health Administration and independent accreditation from the Joint Commission or CARF, and we label any sponsored placement clearly so you always know what you are looking at.

Listing details reflect the levels of care, specialty tracks, and payment types each facility reports, drawn from public licensing records and facility information. Because openings and insurance participation change, confirm current availability and program specifics directly with a center when you reach out. The aim is to give you an accurate starting point for finding care close to home.

Littleton is a historic city in the south Denver metro, spanning parts of Arapahoe, Jefferson, and Douglas counties, with a solid base of addiction treatment. The area has 13 rehab centers offering medical detox, residential, and outpatient care, and you can compare every nearby option through the Colorado rehab directory.

AllHealth Network, the community behavioral health provider for Arapahoe and Douglas counties, is based in Littleton and offers substance use treatment, medication-assisted treatment, and 24/7 crisis care. Public behavioral health for residents with Health First Colorado is coordinated by Colorado Access, the regional accountable entity for the Denver metro. Arapahoe County Public Health also runs a harm-reduction program that launched its Prevention Point mobile unit in Littleton.

Littleton shares the metro’s fentanyl-driven overdose burden, though Arapahoe County reports a recent decline that officials credit partly to widespread naloxone distribution. Statewide, Colorado overdose deaths began falling in 2024, a shift that makes fast access to fentanyl-aware treatment and naloxone especially valuable.

Crisis support: Call or text 988, or reach Colorado Crisis Services at 1-844-493-8255, available 24/7 regardless of insurance.

Health First Colorado: Coverage is coordinated by Colorado Access, the regional accountable entity for the metro.

Free naloxone: Arapahoe County Public Health offers free naloxone and Narcan kiosks across the county.

Insurance accepted: Most Littleton centers accept private insurance, Health First Colorado, and Medicare.

The cost of rehab in Littleton depends on the level of care, program length, and whether you use insurance. Colorado ranks around the middle nationally for treatment affordability, with a statewide residential average of roughly $56,413 without insurance, though most people pay a fraction of that once insurance benefits are applied. The figures below reflect Colorado averages by care type.

Actual costs vary with setting, amenities, and length of stay. Outpatient programs cost far less than residential care and are the most common local format, while medical detox and inpatient stays carry the highest price tags. Insurance, Health First Colorado, and sliding-scale options can lower what you pay out of pocket.

Treatment setting: inpatient and residential care cost more than outpatient.

Program length: 30, 60, and 90-day programs scale in price.

Level of care: medical detox and 24-hour supervision raise costs.

Insurance status: in-network coverage and Medicaid reduce out-of-pocket cost.

Amenities: private rooms and specialized tracks add to the total.

Across the 13 rehab centers serving Littleton, most accept private insurance and self-payment, and many work with Health First Colorado or offer sliding-scale fees. The counts below show how many local facilities report accepting each payment type.

9 accept self-payment or cash

7 accept private health insurance

4 accept Health First Colorado (Colorado Medicaid)

3 accept Medicare

3 offer sliding-scale fees

2 offer financial assistance

2 accept TRICARE

Which option makes the most sense depends on your coverage and income. The subsections below outline how the main payment paths work for Littleton residents.

Health First Colorado (Colorado Medicaid)

Colorado’s Medicaid program, Health First Colorado, covers the full continuum of substance use care, from detox to outpatient counseling and medication-assisted treatment. Benefits are coordinated through Colorado Access, the regional accountable entity for the Denver metro, and AllHealth Network is a strong local starting point for covered care. Four Littleton facilities report accepting Health First Colorado.

Medicare

Medicare covers substance use treatment that is medically necessary, including inpatient care under Part A and outpatient services and counseling under Part B, with Medicare Advantage plans offering the same benefits. Three Littleton area centers accept Medicare.

Military and TRICARE

Veterans and active-duty families have several routes to care. Two area facilities accept TRICARE, and the VA coordinates services through the Denver metro VA system, including the Rocky Mountain Regional VA Medical Center in nearby Aurora. See more rehab resources for veterans and military families.

Insurance and Private Pay

Most Littleton centers in the directory accept private insurance or self-payment, and marketplace plans through Connect for Health Colorado must cover substance use treatment. Coverage varies by plan and network status, so verify benefits before you commit. Major carriers active in Colorado include:

• Anthem Blue Cross and Blue Shield
• Kaiser Permanente
• UnitedHealthcare
• Cigna
• Aetna
• Rocky Mountain Health Plans

Other Low-Cost Options

For those without full coverage, three Littleton centers offer sliding-scale fees, two offer financial assistance, and one offers financing. AllHealth Network serves residents regardless of ability to pay, and treatment scholarships can help close the gap.

Accreditation

Accreditation signals that a program meets independent quality standards. Among Littleton area facilities, two hold Joint Commission accreditation and one carries LegitScript certification. Accreditation is separate from state licensure, which every legitimate Colorado provider must maintain.

Littleton offers care across the continuum, with 5 detox programs, 6 inpatient programs, and 9 outpatient clinics reported locally, plus a partial hospitalization option. Most facilities also treat co-occurring mental health conditions.

5 medical detox facilities

6 inpatient rehab programs

1 partial hospitalization program

9 standard outpatient clinics

8 dual diagnosis programs

Medical detox provides 24-hour supervision to manage withdrawal safely and is the usual first step for opioid or alcohol dependence. Five area programs offer medically supervised detox.

Inpatient and residential rehab provides structured, live-in treatment. Six local inpatient rehab programs serve people who need to step away from daily triggers to focus on early recovery.

Partial hospitalization offers intensive daytime treatment while a person returns home in the evening. One area program provides PHP, bridging residential and standard outpatient care.

Outpatient treatment lets people live at home while attending scheduled sessions, with 9 clinics reported. It suits people balancing work, school, or family, and those stepping down from residential care.

Dual diagnosis care treats addiction alongside conditions like depression or anxiety. Eight reporting facilities address co-occurring disorders, which matters given how often mental health and substance use overlap.

Many Littleton facilities tailor treatment to specific groups and substances. The counts below reflect programs that report each specialty focus.

8 alcohol rehab programs

9 young adult programs

7 men’s programs

5 women’s programs

6 opioid rehab programs

3 LGBTQ+ friendly programs

3 programs for older adults

2 veterans and military programs

Alcohol is a leading treatment focus locally, with eight programs addressing alcohol use disorder, and six treat opioid use disorder. Programs for young adults are widespread, and three facilities offer LGBTQ+ affirming addiction care, alongside tracks for women, men, older adults, and veterans.

Cost should not keep anyone from help. Littleton residents can reach crisis support, treatment access lines, and harm-reduction resources at no charge, including crisis and suicide-prevention support around the clock.

Littleton sits mostly in Arapahoe County, which recorded 194 drug overdose deaths in 2022, among the highest county totals in Colorado, before officials reported a recent decline they attribute in part to expanded naloxone access. Statewide, more than 1,600 Coloradans died of a drug overdose in 2024, but overdose data show fentanyl and other opioid deaths falling sharply over the most recent year measured.
