New health market figures show that private health insurers held spending growth down in 2012.
The figures also show that the federal government put some of its Medicaid spending burden on the shoulders of state and local governments that year.
Anne Martin, an economist in the Office of the Actuary at the Centers for Medicare & Medicaid Services (CMS), and other researchers in the office have included the figures in the government's latest national health expenditures accounts report.
Total national health expenditures increased 3.7 percent in 2012, to $2.8 trillion.
Spending growth was up slightly from 3.6 percent, but about the same as it's been since 2009.
Overall gross domestic product (GDP) grew 4.6 percent.
