HHS says all insurers will still cover them all

"We pressed the White House to specifically address Trump’s promised “1,000%” decrease. His team responded only on condition of anonymity. This time, they said they had an example: in 2023, a certain drug was listed for $521 in the US versus just $45 in Australia, so the US price was roughly 1,000% higher.

But reducing the US price of this drug from $521 to $45 would be a 91% decrease, not a 1,000% cut. If the president wanted to say that some drugs cost 1,000% more in the US than in other countries, he could simply say that; instead, he has stuck with the phony claim of a looming 1,000% cut."

In AstraZeneca drug pricing announcement just now, Trump said some of its meds would get discounts of as much as 654% through TrumpRx

Which is mathematically impossible

But @ddale8.bsky.social looked into this before - and got the White House to explain its math: www.cnn.com/2025/09/23/p...
