Health insurance companies cannot use algorithms or artificial intelligence to determine care or deny coverage to members on Medicare Advantage plans, the Centers for Medicare & Medicaid Services (CMS) clarified in a memo sent to all Medicare Advantage insurers.

The memo—formatted like an FAQ on Medicare Advantage (MA) plan rules—comes just months after patients filed lawsuits claiming that UnitedHealth and Humana have been using a deeply flawed, AI-powered tool to deny care to elderly patients on MA plans. The lawsuits, which seek class-action status, center on the same AI tool, called nH Predict, used by both insurers and developed by NaviHealth, a UnitedHealth subsidiary.

According to the lawsuits, nH Predict produces draconian estimates for how long a patient will need post-acute care in facilities like skilled nursing homes and rehabilitation centers after an acute injury, illness, or event, like a fall or a stroke. And NaviHealth employees face discipline for deviating from the estimates, even though they often don't match prescribing physicians' recommendations or Medicare coverage rules. For instance, while MA plans typically provide up to 100 days of covered care in a nursing home after a three-day hospital stay, using nH Predict, patients on UnitedHealth's MA plan rarely stay in nursing homes for more than 14 days before receiving payment denials, the lawsuits allege.

Death is coming for the old-school gas furnace—and its killer is the humble heat pump. They’re already outselling gas furnaces in the US, and now a coalition of states has signed an agreement to supercharge the gas-to-electric transition by making it as cheap and easy as possible for their residents to switch.

Nine states have signed a memorandum of understanding that says that heat pumps should make up at least 65 percent of residential heating, air conditioning, and water-heating shipments by 2030. (“Shipments” here means systems manufactured, a proxy for how many are actually sold.) By 2040, these states—California, Colorado, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, and Rhode Island—are aiming for 90 percent of those shipments to be heat pumps.

As Apple has stepped up its promotion of its App Store as a safer and more trustworthy source of apps, its operators scrambled Thursday to correct a major threat to that narrative: a listing that password manager maker LastPass said was a “fraudulent app impersonating” its brand.

At the time this article on Ars went live, Apple had removed the app—titled LassPass and bearing a logo strikingly similar to the one used by LastPass—from its App Store. At the same time, Apple allowed a separate app submitted by the same developer to remain. Apple provided no explanation for the reason for removing the former app or for allowing the latter one to remain.

Apple warns of “new risks” from competition

The move comes as Apple has beefed up its efforts to promote the App Store as a safer alternative to competing sources of iOS apps mandated recently by the European Union. In an interview with App Store head Phil Schiller published this month by FastCompany, Schiller said the new app stores will “bring new risks”—including pornography, hate speech, and other forms of objectionable content—that Apple has long kept at bay.
