If someone requires vital help for drug and alcohol addiction and is fortunate enough to be covered through health insurance, many drug treatment programs in Granby accept payment in the form of health insurance and will work with potential clients to determine which rehab services are covered. The majority of private health insurance companies cover outpatient and residential drug rehabilitation, but the time in rehab which is included can fluctuate. Private health insurance will more than likely cover the first 4 weeks of drug rehab, but there are people whose plan is more substantial and may include a more long-term stay in a drug and alcohol treatment facility. It is best to consult with their plan directly and to ask for any help as needed from their rehab program to figure out what is and what is not included by your private health insurance.
