If someone requires vital help for alcohol and drug addiction and dependence and is lucky enough to be covered through health insurance, most drug rehab centers in Cupertino, California accept health insurance and will work with clients to determine which types of treatment are covered. Most private health insurance companies cover outpatient and residential drug and alcohol treatment, but the timeframe which is covered can vary. Private health insurance will typically cover the first month of drug rehab, although there are persons whose plan is more substantial and could also cover a more significant time in a drug treatment program. It is recommended that individuals consult with their plan as soon as possible and to ask for any help as needed from their rehab program to establish what is and what is not included by your private health insurance.
