If an individual must receive treatment for drug addiction and is fortunate enough to be covered under health insurance, most drug treatment centers in Greenbrae, California will accept any type of health insurance and will cooperate with potential clients to see what is and is not insured. The majority of private health insurance entities cover outpatient and inpatient drug and alcohol treatment, although the time which is covered can vary. Private health insurance will more than likely cover the first month of alcohol and drug rehabilitation, but there are people whose insurance is more extensive and may cover a longer stay in a drug treatment center. It is best to seek advice of their plan directly and to ask for any help as needed from their treatment center to find out what is approved by your private health insurance.
