Aegis Treatment Centers LLC
Manteca, California
30 treatment centers across California that work with WellCare.

Inpatient care is unusually well represented among the California centers listed here: 29 of the 30 report offering it, against 23% across the wider directory — more than four times as common. Payment flexibility follows the same pattern, with 28 of the 30 reporting financing or payment plans, roughly three times the directory-wide rate. For someone weighing a residential stay against staying home, that combination is the practical difference between a plan and a wish.
What the listings show is what each facility reports about itself, including the carriers it says it accepts. All 30 report accepting private insurance, Medicaid, Medicare and self-pay. Whether a particular WellCare plan pays, and how much, is a question only WellCare and the facility's billing office can answer for your policy.
Twenty-five of the 30 centers report treating prescription drug use, far above the directory-wide rate, and 26 report treating alcohol and 26 report treating opioids.
Twenty-one of the 30 report supporting pregnant women, against 27% across the directory — a meaningful difference when timing and prenatal coordination are part of the decision.
Spanish is offered by 21 of the 30 and ASL by 18, alongside English at 28 — worth confirming directly if language access will shape who in the family can take part.
Twenty-six of the 30 report state licensing, 25 hold CARF, 25 hold Joint Commission accreditation and 24 are SAMHSA-listed; ask any facility to confirm its current standing.
California's geography shapes treatment more than the paperwork does. Someone in the far north or the eastern desert counties may find the nearest residential bed several hours' drive away, while coastal metros hold most of the inpatient capacity — which is why 28 of the 30 listed centers offering virtual or telehealth care matters so much for the step-down phase, after a stay ends and the drive becomes weekly instead of once.
State parity rules require plans regulated in California to cover substance use and mental health benefits on comparable terms to medical care, and Medi-Cal expanded substance use services sit alongside commercial coverage rather than replacing it. That framework sets a floor, not a promise about your specific benefits, so confirmation with your insurer is still the step that settles it.
Some WellCare plans include addiction treatment benefits, and California's parity requirements mean plans regulated in the state generally have to treat substance use and mental health benefits comparably to medical and surgical ones. What that means in dollars and days still depends on your specific plan, so confirm the details with WellCare using the member number on your card, then confirm again with the facility.
Call the member services number printed on the back of your WellCare card and ask which levels of care are covered, whether prior authorization is required, and which California facilities are in network for your plan. Then call the facility directly, give them your plan details, and ask them to check on their end — facilities bill these plans daily and often catch things a general phone script misses.
Detox is billed as its own level of care and is authorized separately from residential or outpatient treatment on most plans. Ask WellCare specifically about medical detox rather than assuming a yes on rehab covers it, and ask the facility whether they provide detox on site or refer out.
Ask for a written estimate that separates the facility charge from professional fees, and ask what your deductible, copay or coinsurance would be after benefits are applied. Nobody can quote a reliable figure without reading your plan, so treat any number given before verification as provisional.
An in-network facility has a contract with the plan, which usually means a lower share of the cost for you and less billing friction. Out-of-network care may still be partly covered under some plans, but often at a higher cost share — ask WellCare which of the two applies to any California program you are considering.
Many Californians do. If the nearest inpatient bed is hours away, people commonly travel to a metro area for detox and residential care and then step down to outpatient or telehealth closer to home. Twenty-eight of the thirty centers listed here offer virtual or telehealth services, which makes that handoff more workable.
Medi-Cal is California's Medicaid program, and all thirty centers listed here report accepting Medicaid as well as Medicare, private insurance and self-pay. If your coverage situation is changing or you hold more than one form of coverage, ask both the plan and the facility how billing would be coordinated.
Ask what they typically see for the specific level of care you need, since detox, residential and outpatient rarely have the same availability. Ask too whether they hold a waitlist, whether they can start you in outpatient or telehealth while a bed opens, and whether prior authorization is likely to add days.
