To Centene Chairman and CEO Michael Neidorff, there is no question that the Affordable Care Act needs fixing.
In response to Donald Trump's promise to repeal Obamacare, Neidorff said that while the system has been successful for Centene, which focuses on government-sponsored health-care programs, its structural pitfalls leave much to be desired.
"You could do it either way. You could start over, or you could look at what you have now and say, 'What are the fundamental issues?' And there are structural issues: number of tiers, who's covered, what's happening, and you can repair it," Neidorff told CNBC's "Squawk Box" on Thursday.
Although Obamacare only covers a small portion of Centene's business — less than 5 percent of nearly 11.5 million people — Neidorff said the rest of its wide-ranging coverage cannot go ignored by the Trump administration.
"Whatever they want to do, it's not something they're going to be able to do tomorrow morning," the CEO said. "Because you do have over … 20 million lives covered, and you need to work through that, not just drop them, but figure out what you're moving them to."
