If an individual requires vital help for drug and alcohol addiction and dependence and is lucky enough to be covered through health insurance, the vast majority drug treatment programs in Lewiston accept health insurance and will work with clients to find out which rehab services are approved. The majority of private health insurance entities cover outpatient and residential drug and alcohol rehab, although the time which is considered covered can vary. Private health insurance most often covers the first 4 weeks of drug and alcohol rehab, but there are people whose insurance is more extensive and can cover a more significant time in a drug rehab program. It is asked that potential clients consult with their insurance company directly in liaison with the rehabilitation program to establish which services may be included by their private health insurance.
