If an addict requires vital help for drug addiction and is lucky enough to be covered under health insurance, many drug rehabilitation centers in Ontario, California accept health insurance and will work with people to determine what is and is not covered. Many private health insurance companies will cover outpatient and inpatient drug rehabilitation, but the time in rehab which is included can fluctuate. Private health insurance will typically cover the first month of drug and alcohol treatment, but there are persons whose coverage is more substantial and can cover a more significant residence in a drug rehabilitation program. It is asked that potential clients speak with their insurance company directly in liaison with the rehabilitation facility to determine which services may be covered by their private health insurance.
