If an addict is in need of treatment for drug and alcohol addiction and is fortunate enough to be covered through health insurance, the vast majority drug rehab centers in San Marcos, California will accept any type of health insurance and will liaise with individuals to determine what is and is not covered. Most private health insurance entities cover outpatient and residential drug and alcohol rehab, but the timeframe which is included can vary. Private health insurance will more than likely cover the first 30 days of alcohol and drug rehabilitation, although there are people whose coverage is more substantial and can include a more significant stay in a drug rehab facility. It is recommended that individuals consult with their insurance company directly in liaison with the rehabilitation center to find out which services may be covered by your private health insurance.
