If an individual requires help for drug and alcohol addiction and dependence and is fortunate enough to be covered under health insurance, the vast majority alcohol and drug rehab programs in Costa Mesa accept health insurance and will work with individuals to find out what is and is not approved. Most private health insurance entities will cover outpatient and residential drug and alcohol treatment, but the timeframe which is covered can fluctuate. Private health insurance most often covers the first month of drug and alcohol rehabilitation, although there are people whose coverage is more extensive and may extend to a longer residence in a drug and alcohol rehabilitation center. It is asked that potential clients speak with their plan directly in liaison with the rehabilitation facility to find out which services may be covered by their private health insurance.
