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