Some people are covered through state financed insurance because they fail to meet the eligibility requirements for Medicaid. Some states however offer affordable health insurance to those who cannot afford private health insurance. State financed health insurance programs will in some cases cover the costs associated with substance abuse treatment at a variety of drug rehab programs around the country. State financed insurance other than Medicaid may cover both inpatient or outpatient substance abuse treatment services. To find out which rehabilitation facilities will accept state financed insurance, consult a drug and alcohol treatment specialist.
