If someone requires treatment for drug addiction and is one of the fortunate clients to be covered through health insurance, the vast majority alcohol and drug rehabilitation centers in Martinez, California accept payment in the form of health insurance and will work with people to determine which rehab services are approved. The majority of private health insurance entities will cover outpatient and residential drug rehab, but the time which is covered can vary. Private health insurance most often covers the first month of drug and alcohol rehabilitation, but there are individuals whose plan is more substantial and may extend to a more long-term time in an alcohol and drug rehabilitation center. It is best to speak with their insurance company directly with the help of their rehab center to figure out what is and what is not approved by their private health insurance.
