Rehabs That Take Contra Costa Health Plan
Contra Costa Health Plan is unusual among Medi-Cal plans because the county both insures and delivers care, running its own hospital, clinics and behavioral health services. Addiction treatment is covered at no cost, including withdrawal management, residential care, outpatient services and medication for opioid use disorder.
That arrangement means the plan, the county behavioral health department and the treating clinicians frequently sit inside a single organization. It removes some of the handoffs that fragment care elsewhere, and it makes the county access line the one sensible place to start rather than the plan.

Does Contra Costa Health Plan Cover Rehab?
Yes, at no cost to members. Coverage includes assessment, withdrawal management, residential treatment, intensive outpatient, outpatient counseling, medication for opioid use disorder, case management and recovery services.
Contra Costa is one of a small number of counties in the country operating its own health plan alongside its own hospital and clinic system. The plan is publicly governed and the care is largely publicly delivered, which changes how the pieces connect.
One System, One Number
Contra Costa Health runs the plan, the regional medical center, the health centers and behavioral health services under one county department. For addiction treatment that means the county access line reaches an organization that can both authorize and provide, rather than referring you outward. It is the number to start with.
Coverage by Level of Care
Withdrawal Management
Covered at ambulatory and residential intensities. Alcohol and benzodiazepine withdrawal carry seizure risk, and emergency care applies regardless of authorization, with the county’s own emergency department part of the same system.
Residential Treatment
Covered with county authorization against ASAM criteria. Capacity within the county is limited relative to demand, and placement elsewhere in the Bay Area is ordinary rather than exceptional.
Intensive Outpatient and Outpatient
Both covered and generally quicker to start. The county operates outpatient services directly in several parts of the county, which makes availability more predictable than relying on contracted providers alone.
Medication for Opioid Use Disorder
Buprenorphine, methadone and naltrexone are covered. Contra Costa has worked to make buprenorphine available through its health centers and emergency department rather than only through specialist clinics, which removes a common delay.
A County of Two Halves
Contra Costa contains both affluent suburbs and some of the Bay Area’s most economically stressed communities along the northern waterfront. Richmond, Antioch, Pittsburg and Bay Point carry a heavier burden of addiction and overdose than the county’s overall figures suggest.
Services are distributed accordingly, but transport across the county is slow and the eastern towns are a long way from the western ones. Medi-Cal covers non-emergency medical transport, which is worth asking about rather than assuming a bus route will do. Telehealth is covered and removes the journey for counseling and medication management.
Verifying Coverage
Ask before you admit
Is this specific facility in network, and what does my plan pay if it is not?
What are my deductible, coinsurance and out-of-pocket maximum this year, and how much have I already met?
Does detox, residential, PHP or IOP require prior authorization?
How is continued stay reviewed, and what is the appeal route if care is denied?
Grievances go to the plan or the county, with a state fair hearing available beyond that. Where residential treatment is refused, ask what criteria were applied and appeal on clinical grounds.
What Treatment Costs
Members pay nothing. The rates below show private market costs in the Bay Area for context.
| Level of care | Monthly | Daily |
|---|---|---|
| Medical detox (7–14 days) | $1,500 – $5,200 per week | $215 – $745 |
| Residential inpatient | $6,200 – $26,000 | $205 – $865 |
| PHP | $7,200 – $14,000 | $240 – $465 |
| IOP | $2,700 – $9,200 | $90 – $305 |
| Outpatient | $1,300 – $5,200 | $45 – $175 |
Coverage for Specific Substances
Fentanyl and methamphetamine dominate, frequently in the same supply, and overdose deaths have concentrated in the county’s northern and eastern communities. Fentanyl responds to medication treatment; methamphetamine has no approved medication, so behavioral programs and contingency management carry it.
Alcohol remains the most common substance overall and carries the clearest withdrawal danger. Naloxone is covered and distributed through county programs, and it is worth having wherever someone is still using.
Housing and Reentry
The plan administers CalAIM Enhanced Care Management and Community Supports, which can include housing navigation and tenancy support for members with complex needs. Because the county delivers much of the care as well, coordination between treatment and those supports is more achievable here than in most places.
California also now provides Medicaid services before release from custody. Ask about pre-release enrollment and a direct handover into treatment, since the days immediately after release carry severe overdose risk.
Eligibility
California extended full-scope Medi-Cal to income-eligible residents regardless of immigration status, and eligibility rests on current income rather than last year’s. Anyone refused in the past is worth reapplying.
Commercial Members
Contra Costa Health Plan also offers commercial coverage to some employer groups and to In-Home Supportive Services workers, alongside its Medi-Cal business. Those members hold ordinary insurance with deductibles and cost sharing rather than Medi-Cal.
If your coverage came through work rather than through Medi-Cal eligibility, say so, because the treatment route and what you pay both differ. The county access line can still point you to services, but authorization and cost sharing follow the commercial plan terms.
