If someone is in need of treatment for drug addiction and dependence and is lucky enough to be covered under health insurance, the vast majority alcohol and drug treatment facilities in Calistoga, California accept payment in the form of health insurance and will work with clients to find out what is and is not insured. Most private health insurance companies will cover outpatient and inpatient drug rehab, but the time in rehab which is considered covered can fluctuate. Private health insurance will typically cover the first month of alcohol and drug rehabilitation, but there are clients whose plan is more extensive and could also cover a longer time in a drug and alcohol rehab program. It is recommended that individuals seek advice of their plan directly in liaison with the rehab program to establish which services may be included by your private health insurance.
