Frequently Asked Questions
How much does 90 day rehab cost in California?
The cost of 90 day rehab in California varies widely. Insurance plans including Medi-Cal, Kaiser, Blue Cross, and Aetna typically cover a significant portion of residential treatment at in-network facilities. Out-of-pocket costs depend on your specific plan, the facility's rates, and length of stay. Many facilities also offer sliding-scale fees or payment plans.
How long does 90 day rehab typically last?
Most residential treatment programs in California run 30, 60, or 90 days, with some offering long-term programs of six months or more. Length of stay is determined by clinical need, insurance authorization, and the specific program's model.
Does insurance cover 90 day rehab in California?
Yes. Under the Affordable Care Act and California parity laws, most insurance plans are required to cover addiction treatment. Medi-Cal covers residential treatment through the DMC-ODS program in participating counties. Private insurance plans (Kaiser, Blue Cross, Anthem, Aetna, Cigna, UnitedHealthcare) typically cover medically necessary residential care.
What's the difference between residential and inpatient treatment?
The terms are often used interchangeably. 'Inpatient' traditionally referred to hospital-based treatment with 24-hour medical staff, while 'residential' referred to non-hospital live-in programs. Today most licensed residential facilities in California provide round-the-clock clinical supervision comparable to inpatient care.
Will I be able to detox before starting 90 day rehab?
Yes. Most California residential facilities either provide on-site medical detox or coordinate detox at a partnering facility before treatment begins. Detox typically lasts 3 to 10 days depending on the substance and your medical history.
