The Government has been making "misleading" comments about controversial pension reforms, the British Medical Association (BMA) said.
As doctors up and down the country take part in industrial action the union spoke out to dispel "partial representations of the facts".
Andrew Lansley's claims that taxpayers subsidise £4 out of every £5 of doctors' pensions is false, the union said.
The NHS pension scheme does not work by building up a pension pot - staff working now pay for the pensions of NHS staff who are retired.
The scheme currently brings in £2 billion more than it pays out - this money goes back to the Treasury.
