Governments, hospitals and individuals account for $86 billion in spending on health care for uninsured Americans, according to a new report from the Henry J. Kaiser Family Foundation.

Uninsured patients will spend $30 billion of their own money on health services this year, the report estimated, and receive $56 billion worth of uncompensated care, including $43 billion in government support. The latter figure includes $18 billion in Medicaid and Medicare payments to hospitals and $15 billion in indigent care and other expenditures by state governments.

However, the study found that the uninsured receive less than half the health services that insured individuals get on an annual basis, and pay far more out of pocket for the care they do receive.

Researchers said that spending would increase $122.6 billion if all currently uninsured Americans got health insurance. Government spending would increase as a result, the report said, but some money also would be redirected from programs that now subsidize the uninsured.

"From society's perspective, covering the uninsured is still a good investment," said lead study author Jack Hadley of George Mason University. "Failure to act in the near term will only make it more expensive to cover the uninsured in the future, while adding to the amount of lost productivity from not insuring all Americans."

The study appeared in the journal Health Affairs.
