If someone requires help for drug addiction and dependence and is lucky enough to be covered through health insurance, most alcohol and drug rehabilitation centers in Sonoma, California accept health insurance and will cooperate with clients to find out which types of treatment are approved. The majority of private health insurance entities will cover outpatient and residential drug and alcohol treatment, although the time which is covered can vary. Private health insurance will typically cover the first 4 weeks of alcohol and drug rehab, but there are persons whose coverage is more extensive and can cover a longer time in a drug and alcohol treatment program. It is asked that potential clients consult with their plan as soon as possible with the help of their treatment program to figure out what is covered by their private health insurance.
