If an addict must receive treatment for alcohol and drug addiction and dependence and is lucky enough to be covered under health insurance, many drug and alcohol rehabilitation centers in Hilton Head Island, South Carolina accept health insurance and will liaise with potential clients to find out which rehab services are approved. Many private health insurance companies will cover outpatient and inpatient drug and alcohol rehabilitation, although the time in rehab which is included can fluctuate. Private health insurance most often covers the first 30 days of alcohol and drug rehabilitation, although there are people whose plan is more extensive and can extend to a longer residence in an alcohol and drug treatment center. It is asked that potential clients consult with their insurance company directly in liaison with the rehabilitation program to figure out what is and what is not approved by your private health insurance.
