If an addict requires help for drug addiction and dependence and is lucky enough to be covered under health insurance, many drug and alcohol treatment programs in Gilroy, California accept payment in the form of health insurance and will cooperate with potential clients to find out what is and is not approved. Many private health insurance companies will cover outpatient and residential alcohol and drug rehab, but the time in rehab which is considered covered can fluctuate. Private health insurance most often covers the first 4 weeks of drug rehabilitation, but there are persons whose coverage is more extensive and may include a more significant stay in an alcohol and drug rehabilitation facility. It is best to speak with their plan as soon as possible with the help of their rehab center to determine what is included by their private health insurance.
