If an addict must receive treatment for alcohol and drug addiction and is lucky enough to have health insurance, most drug and alcohol rehab centers in Signal Hill will accept any type of health insurance and will cooperate with potential clients to determine which types of treatment are approved. Many private health insurance companies will cover outpatient and residential drug and alcohol rehab, but the timeframe which is considered covered can fluctuate. Private health insurance will more than likely cover the first 30 days of alcohol and drug rehabilitation, although there are clients whose insurance is more substantial and can cover a more long-term stay in an alcohol and drug rehab center. It is best to consult with their plan as soon as possible and to ask for any help as needed from their rehabilitation program to determine which services may be approved by their private health insurance.
