If someone requires treatment for drug addiction and is fortunate enough to be covered through health insurance, many drug and alcohol rehab centers in Katy, TX. will accept any type of health insurance and will liaise with potential clients to determine what is and is not covered. Many private health insurance companies cover outpatient and residential drug rehab, but the time which is included can vary. Private health insurance will more than likely cover the first 30 days of drug rehab, although there are persons whose coverage is more substantial and can include a more significant residence in a drug and alcohol treatment program. It is best to seek advice of their insurance company directly and to ask for any help as needed from their treatment center to figure out what is covered by their private health insurance.
