If someone requires treatment for drug and alcohol addiction and dependence and is one of the fortunate clients to be covered under health insurance, most drug rehab programs in Centennial, Colorado accept payment in the form of health insurance and will cooperate with potential clients to find out which rehab services are insured. The majority of private health insurance companies cover outpatient and inpatient alcohol and drug rehab, but the time which is included can fluctuate. Private health insurance will more than likely cover the first 4 weeks of drug treatment, although there are people whose plan is more substantial and can cover a more long-term residence in a drug treatment center. It is best to seek advice of their insurance company as soon as possible in liaison with the treatment facility to establish what is included by their private health insurance.
