If someone requires vital help for drug and alcohol addiction and dependence and is one of the fortunate clients to be covered through health insurance, many drug rehabilitation centers in Covina, CA. accept payment in the form of health insurance and will liaise with clients to determine what is and is not insured. Most private health insurance entities will cover outpatient and residential alcohol and drug rehab, but the time which is included can vary. Private health insurance will more than likely cover the first 4 weeks of alcohol and drug rehab, but there are individuals whose plan is more substantial and may cover a more long-term stay in a drug rehabilitation program. It is best to seek advice of their plan directly with the help of their treatment facility to figure out what is and what is not approved by their private health insurance.
