I'd propose the following reforms, although this is a somewhat simplified list.
1) No discrimination for age, gender or pre-existing conditions, but backed a government funded risk equalization program.
2) Tort reform.
3) Government negotiated drug prices.
4) Criminal prosecution for giving so much as lollypop to a doctor if you are the Pharmaceutical business.
5) More conflict of interest laws. Notably doctors who refer patients to other businesses they own.
6) Voucher packages to the poor to buy health insurance.
7) Various regulations for allowed insurance, such as preventing in/out of network nonsense or lifetime maximums.
8) A public option isn't inherently required, but providing some competition to get the system rolling would be beneficial.
The primary goals are to get everyone covered, remove incentives for bad behavior and dramatically cut administrative overhead.
