Pregnancy to cost 425% more under Donald Trump's health plan compared to Obamacare

US citizens with the most serious forms of cancer could have to pay up to $140,000 (£109,000) more for health insurance under a proposed amendment to Donald Trump's new healthcare bill, analysts have claimed.

Fierce debate over what the bill will mean for people with pre-existing conditions has threatened to derail a fresh bid to push the reforms through after they collapsed in March.

The President has tried to make clear that provisions for people with illnesses such as cancer and diabetes will not be reduced, saying earlier this week the new healthcare plan "will be every bit as good on pre-existing conditions as Obamacare". House Speaker Paul Ryan said the latest changes to the bill will "lower premiums while keeping protections for the most vulnerable in place" with a modest pool of money to help people afford health insurance.

Wavering moderate Republicans had worried that the legislation to overhaul President Barack Obama's 2010 signature healthcare law would leave too many people with pre-existing medical conditions unable to afford coverage. But estimates of how much healthcare premiums could rise under the new legislation, revamped to attract most hard-line conservatives and some Republican centrists, show people could end up paying much more under so-called 'Trumpcare'. A 40-year-old with a severe form of cancer such as lung or brain cancer could be liable for a $71,880 (£56,000) surcharge, while those with metastatic cancer could see a rise of $140,510, according to calculations by liberal think tank Center for American Progress.

People with colorectal, kidney and other cancers, and those with breast cancer under 50, may have to pay a surcharge of $28,230 (£22,000), and a middle-aged person with autism could have to pay $5,420 (£4,200) for coverage.And a completed pregnancy, with no or minor complications, will result in a premium hike of $17,060 - a 425% increase. The organisation said proposals allowing individual states to protect high-risk patients through funding pools or risk-sharing programmes.
