If someone requires vital help for drug addiction and dependence and is lucky enough to have health insurance, most drug rehabilitation centers in Los Altos, California accept health insurance and will work with people to determine which rehab services are insured. Many private health insurance companies will cover outpatient and residential drug and alcohol rehabilitation, but the time which is covered can fluctuate. Private health insurance most often covers the first month of drug and alcohol treatment, but there are clients whose plan is more substantial and could also cover a more significant time in an alcohol and drug rehabilitation program. It is recommended that individuals speak with their plan as soon as possible in liaison with the treatment facility to determine what is and what is not included by your private health insurance.
