If an addict requires help for drug and alcohol addiction and is one of the fortunate clients to be covered under health insurance, many drug and alcohol rehab programs in Simi Valley, California will accept any type of health insurance and will cooperate with people to find out what is and is not approved. Most private health insurance companies cover outpatient and inpatient drug rehabilitation, but the timeframe which is considered covered can fluctuate. Private health insurance most often covers the first 4 weeks of drug and alcohol rehab, but there are persons whose insurance is more extensive and may cover a more long-term stay in a drug and alcohol rehabilitation center. It is recommended that individuals consult with their insurance company directly with the help of their rehab center to find out what is and what is not included by their private health insurance.
