If a man or woman requires treatment for drug and alcohol addiction in Monrovia, California and is fortunate enough to be covered through health insurance, the majority of drug and alcohol rehabilitation programs accept health insurance and will work with clients to discover which treatment programs are approved. A number of private health insurance companies in Monrovia cover the costs of outpatient and inpatient drug rehab, but the length of time which is included can vary. Private health insurance will more than likely cover the first month of alcohol and drug treatment, although there are people whose insurance coverage is more substantial and may include a longer stay in a Monrovia, California drug and alcohol rehabilitation facility. It is best to consult with their insurance company directly with the help of their rehabilitation center to decide what is and what is not covered by their private health insurance.
