If someone must receive treatment for alcohol and drug addiction and is lucky enough to be covered under health insurance, the vast majority drug rehab programs in Cerritos, California accept health insurance and will work with clients to determine which types of treatment are insured. The majority of private health insurance entities cover outpatient and inpatient drug rehab, although the time which is covered can vary. Private health insurance will more than likely cover the first 4 weeks of alcohol and drug treatment, although there are people whose coverage is more substantial and may include a longer stay in an alcohol and drug treatment facility. It is recommended that individuals speak with their plan as soon as possible and to ask for any help as needed from their treatment facility to establish what is approved by your private health insurance.
