Drug and Alcohol Rehabs in Colusa, CA
Colusa sits on the west bank of the Sacramento River in the northern valley, the seat of Colusa County.
The town was laid out in 1850 at the head of navigation for river steamers, and the 1861 courthouse is among the oldest still in use in California.
The surrounding land grows a large share of the state’s rice, and the Sacramento National Wildlife Refuge complex nearby holds hundreds of thousands of wintering waterfowl on the Pacific Flyway.
Highway 20 and Highway 45 meet here, putting Yuba City around 40 minutes east and Williams fifteen minutes west on Interstate 5.
California recorded a drug overdose death rate roughly 6 percent below the national figure in 2024.
Methamphetamine was involved in around 57 percent of California overdose deaths that year, more than any other substance, while fentanyl drives the opioid share.
County rates in 2024 ranged from 11.3 per 100,000 in Napa County to 91.5 in Lake County, both in Northern California.
Colusa County does not participate in the Drug Medi-Cal Organized Delivery System. Medi-Cal members here receive the narrower State Plan Drug Medi-Cal benefit rather than the full ASAM continuum available in the 40 counties that do, which is worth knowing before you start calling. Neighboring Glenn County is also outside it, so this stretch of the west valley sits under State Plan Drug Medi-Cal.
Which Level of Care Do You Need
The counts below reflect the 1 Colusa facility listed in this directory.
Medically Supervised Detox
Detox manages withdrawal under clinical observation, usually across several days, and is where treatment begins for anyone physically dependent on alcohol, opioids or benzodiazepines. The Colusa facility does not offer detox. Marysville has four around 50 minutes east, the strongest detox concentration in Northern California.
Inpatient Residential Treatment
Residential care provides a structured live-in setting for weeks or months. The Colusa facility does not offer it. Marysville has two around 50 minutes east and Sacramento eight within 90 minutes south-east.
Outpatient, IOP and PHP Treatment
Outpatient care lets you live at home while attending sessions. The Colusa facility offers outpatient services and IOP with medication-assisted treatment and telehealth. For a rural county seat that combination covers most of what people need day to day. It does not offer PHP.
Dual Diagnosis and Co-Occurring Disorders Treatment
Dual diagnosis care treats a substance use disorder and a mental health condition together rather than in sequence. The Colusa facility indicates it treats co-occurring disorders.
Sober Living Homes and Transitional Living
Sober living homes provide drug-free housing after formal treatment ends. This directory does not list recovery residences separately. The California Consortium of Addiction Programs and Professionals certifies residences statewide.
Addiction Treatment Cost and Insurance Coverage
The single facility here accepts Medi-Cal and Medicare, though the county is outside DMC-ODS.
How Much Does Addiction Rehab Cost in Colusa
IOP in Colusa runs roughly $3,000 to $10,000 a month and outpatient $1,200 to $5,000, both available locally with medication-assisted treatment. Detox, residential and PHP all mean traveling east, at $7,000 to $24,000, $6,000 to $45,000 and $7,500 to $15,000 monthly. The Colusa facility accepts Medi-Cal and Medicare.
Colusa County sits outside DMC-ODS, so the Medi-Cal benefit here is the narrower State Plan version. Having local IOP and medication-assisted treatment on Medi-Cal is more than most counties outside the system manage.
| Level of care | Monthly | Daily |
|---|---|---|
| Medical detox (inpatient) | $7,000 – $24,000 | $230 – $800 |
| Residential inpatient | $6,000 – $45,000 | $200 – $1,500 |
| PHP | $7,500 – $15,000 | $250 – $500 |

Does Insurance Cover Rehab in Colusa
Yes. Federal parity law requires most health plans to cover substance use treatment on terms comparable to medical care. The Colusa facility accepts Medi-Cal and Medicare. Partnership HealthPlan of California is the Medi-Cal managed care plan across Colusa County, and the county offers the narrower State Plan Drug Medi-Cal benefit.
Medi-Cal carries no premium and no copay for substance use treatment. If you are uninsured, an eligibility check costs nothing.
Free and State-Funded Addiction Rehab in Colusa, CA
Publicly funded care is available locally, though narrower than in DMC-ODS counties.
The listed facility accepts Medi-Cal, and an eligibility check costs nothing.
Colusa County Behavioral Health administers State Plan Drug Medi-Cal locally and can advise on what is covered.
The California Naloxone Distribution Project supplies naloxone free to community organizations, and Never Use Alone on 800-484-3731 stays on the line with people using alone.
More Help and Recovery Support
Colusa Medical Center serves the county. There is no trauma center here; serious cases go to Enloe in Chico or the Sacramento systems, each around an hour away.
Alcoholics Anonymous meets in Colusa and the surrounding valley towns. Narcotics Anonymous operates through the Northern California region. Given the distances and local telehealth, online options are worth having identified in advance. Adjacent Yuba City, Willows and Marysville carry further options.
