If someone requires help for drug addiction and dependence and is fortunate enough to be covered through health insurance, most drug and alcohol treatment centers in San Carlos will accept any type of health insurance and will cooperate with people to find out which types of treatment are insured. The majority of private health insurance entities cover outpatient and residential alcohol and drug rehab, although the timeframe which is considered covered can fluctuate. Private health insurance most often covers the first 30 days of drug and alcohol rehabilitation, but there are clients whose plan is more extensive and could also extend to a more long-term residence in an alcohol and drug treatment center. It is asked that potential clients seek advice of their insurance company as soon as possible in liaison with the treatment center to figure out what is and what is not covered by your private health insurance.
