Tenet, which reported a $192 million loss on $19.6 billion of revenue in 2016, cut ties with Humana last fall after the two sides couldn't agree on a new reimbursement contract. That means patients with Humana health insurance, most of whom are on Medicare, currently can't go to Tenet facilities at the lower in-network rates. It's a big reason why Tenet recorded fewer patient hospitalizations and surgeries.

Key quote: But Tenet doesn't mind playing chicken with health insurance companies. Tenet CEO Trevor Fetter made it clear on a conference call Tuesday that the company will only own hospitals and surgery centers if those facilities have a dominant position in the local market. Why? To extract better prices: "We have not changed our strategy, which is either we're all-in or we're all-out...that makes for a high-stakes negotiation on both sides, which has worked to our advantage."

Twitter will start pinning notices to the top of all U.S. Twitter users’ timelines warning that results in next week’s election may be delayed and that they may encounter misinformation on mail-in voting.

Why it matters: Delayed election results are expected across many states that are handling unprecedented amounts of absentee and mailed ballots, which President Trump has baselessly called "very dangerous" and "corrupt."

NASA confirms water exists on sunny parts of the Moon


Water on the Moon might be more easily accessible than previously thought, opening up new possible avenues for future human exploration, according to a new study.

Why it matters: NASA is aiming to send people back to the Moon as part of its Artemis program by 2024, with plans to eventually create a sustainable presence on the lunar surface. That sustainability relies on mining the moon for its resources, like water.

Vice President Mike Pence no longer plans to attend the Senate's final confirmation vote for Judge Amy Coney Barrett, a Pence aide confirmed to CNN and Politico on Monday. On Sunday, Senate Democrats claimed that his presence after possible exposure to the coronavirus would be a "violation of common decency."

Driving the news: Five of Pence's aides were recently diagnosed with COVID-19, including his chief of staff, who is currently quarantining. Pence has continued his campaign travel despite his possible exposure, which goes against CDC guidelines.
