The UK ranks sixth among the G7 nations for the amount it spends on healthcare.
Out of the G7 group, only Italy spent less in 2014, according to the Office for National Statistics (ONS).
The new ONS analysis, which includes both public and private spending, shows that the UK's total healthcare spending in 2014 was £179 billion, or 9.9% of Gross Domestic Product (GDP).
As a percentage of GDP, the UK spent less on healthcare than USA, Japan, France, Germany and Canada.
The analysis comes after the head of the Commons Health Committee accused the Government of giving a "false impression" about increasing funding for the NHS.
Dr Sarah Wollaston said that NHS per capita spending will actually fall in 2018/19.
In a letter to Chancellor Philip Hammond she criticised the Government's stance and the presentation that NHS England was "awash with cash".
On Monday Dr Wollaston warned a "false impression" was being given that the NHS was being boosted by £10 billion over the five years of its spending review, saying the real figure was actually £4.5 billion.
