U.S. health spending accounted for $2.9 trillion in U.S. spending in 2013, or 17.4 percent U.S. gross domestic product (GDP).

National health expenditure (NHE) grew a total of 3 percent between 2012 and 2013, and 2.9 percent per person.

The total share of GDP going to health care held steady.

Micah Hartman and other analysts at the Office of the Actuary at the Centers for Medicare & Medicaid Services (CMS) published the NHE data in a report in Health Affairs, an academic journal that focuses on health care delivery and health finance.

That year, by coincidence, Medicare spending and Medicaid spending also had a 4 percent growth rate.

Because health insurers were effective at holding health care spending down in 2013, the “net cost of insurance” — the difference between premiums earned and benefits paid — actually grew 5 percent, to about $174 billion.
