If an individual must receive vital help for alcohol and drug addiction and dependence and is fortunate enough to be covered under health insurance, most drug and alcohol rehabilitation programs in Petaluma, California will accept any type of health insurance and will cooperate with clients to find out what is and is not insured. Many private health insurance entities will cover outpatient and inpatient drug rehab, although the time which is covered can vary. Private health insurance will more than likely cover the first 30 days of drug treatment, but there are clients whose insurance is more extensive and may cover a longer stay in a drug rehab facility. It is best to speak with their insurance company directly with the help of their rehab program to establish what is and what is not included by your private health insurance.
