If someone requires treatment for drug and alcohol addiction and dependence and is lucky enough to be covered under health insurance, most drug rehab centers in Melissa will accept any type of health insurance and will work with people to determine which rehab services are approved. Many private health insurance entities cover outpatient and residential drug rehab, but the time in rehab which is considered covered can fluctuate. Private health insurance will typically cover the first 4 weeks of drug and alcohol rehabilitation, but there are clients whose plan is more extensive and can include a more significant time in an alcohol and drug treatment program. It is recommended that individuals seek advice of their plan directly with the help of their rehabilitation center to establish which services may be covered by their private health insurance.
