If an addict is in need of help for alcohol and drug addiction and dependence and is one of the fortunate clients to be covered under health insurance, most drug and alcohol treatment programs in Essex will accept any type of health insurance and will cooperate with potential clients to find out what is and is not insured. The majority of private health insurance companies will cover outpatient and residential alcohol and drug treatment, although the time which is considered covered can fluctuate. Private health insurance will more than likely cover the first 4 weeks of alcohol and drug treatment, but there are people whose coverage is more extensive and can extend to a longer stay in a drug rehab program. It is best to speak with their insurance company directly and to ask for any help as needed from their rehabilitation facility to establish which services may be included by their private health insurance.
