If an addict must receive treatment for drug and alcohol addiction and dependence and is fortunate enough to be covered under health insurance, many drug and alcohol rehabilitation facilities in Las Vegas, Nevada will accept any type of health insurance and will cooperate with potential clients to determine which rehab services are covered. Many private health insurance companies cover outpatient and residential drug and alcohol rehabilitation, but the time in rehab which is considered covered can vary. Private health insurance will more than likely cover the first 4 weeks of alcohol and drug rehabilitation, although there are people whose plan is more substantial and may extend to a more long-term residence in a drug rehabilitation center. It is asked that potential clients consult with their insurance company directly in liaison with the rehabilitation program to establish what is approved by their private health insurance.
