If someone requires help for alcohol and drug addiction and is lucky enough to be covered under health insurance, the vast majority drug and alcohol rehabilitation facilities in Three Rivers, Michigan accept payment in the form of health insurance and will liaise with clients to find out which types of treatment are insured. The majority of private health insurance entities cover outpatient and residential alcohol and drug treatment, although the time in rehab which is considered covered can vary. Private health insurance will more than likely cover the first 4 weeks of drug rehab, although there are clients whose coverage is more extensive and can extend to a longer residence in an alcohol and drug treatment facility. It is best to speak with their insurance company directly and to ask for any help as needed from their treatment center to find out what is and what is not covered by your private health insurance.
