If someone must receive treatment for drug addiction and dependence and is fortunate enough to be covered through health insurance, the vast majority drug treatment facilities in Westwood, CA. accept health insurance and will work with individuals to see what is and is not covered. The majority of private health insurance companies cover outpatient and residential drug and alcohol rehab, although the time in rehab which is considered covered can vary. Private health insurance will typically cover the first month of drug treatment, but there are people whose plan is more substantial and can extend to a more long-term residence in a drug and alcohol treatment program. It is recommended that individuals consult with their plan as soon as possible and to ask for any help as needed from their rehabilitation facility to establish which services may be covered by your private health insurance.
