If someone must receive help for drug addiction and is fortunate enough to have health insurance, the vast majority alcohol and drug treatment centers in Trenton accept health insurance and will work with potential clients to see which rehab services are covered. Many private health insurance companies cover outpatient and residential drug rehabilitation, although the timeframe which is considered covered can vary. Private health insurance will typically cover the first month of alcohol and drug rehabilitation, but there are persons whose coverage is more extensive and can extend to a longer residence in an alcohol and drug rehabilitation center. It is best to seek advice of their insurance company as soon as possible and to ask for any help as needed from their treatment program to figure out which services may be approved by their private health insurance.
