If someone must receive vital help for drug and alcohol addiction and dependence and is fortunate enough to have health insurance, many drug and alcohol rehabilitation facilities in Oakland, California accept health insurance and will cooperate with potential clients to see what is and is not insured. The majority of private health insurance entities cover outpatient and inpatient alcohol and drug rehab, but the time in rehab which is covered can fluctuate. Private health insurance will typically cover the first 4 weeks of drug rehabilitation, although there are persons whose insurance is more extensive and may cover a longer time in a drug rehab facility. It is asked that potential clients speak 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 approved by your private health insurance.
