"In contrast to other chronic diseases, funding for addiction treatment disproportionately comes from government sources. More than three quarters—77 percent—of treatment costs are paid by federal, state and local governments, including Medicaid and Medicare.
"Private insurance covers only 10 percent of addiction treatment costs, with out-of-pocket expenditures and other private funding making up the remaining percentage. In contrast, private insurance pays for approximately 37 percent of general medical costs. The passage of federal parity and health care reform legislation should help address this imbalance in the future.
"On an individual level, nearly half of those receiving treatment reported using their own money to pay for their care, and 34.8 percent report using private health insurance."
