Biden administration proposes Medicare, Medicaid coverage of pricey weight loss drugs

In one of its last major policy actions, the Biden administration on Tuesday proposed a rule that would allow Medicare and Medicaid to cover weight loss drugs for patients with obesity.

The rule — if greenlit by the incoming Trump administration — would dramatically expand access to drugs like Wegovy and Zepbound that have shown remarkable efficacy in helping patients lose weight, but at a steep price tag of roughly $40 billion over a decade for federal and state governments.

Currently, Medicare is forbidden by statute from covering drugs for weight loss, while only a handful of state Medicaid programs pay for the medications. But “people with obesity deserve to have affordable access to medication and support,” CMS Administrator Chiquita Brooks-LaSure said on a call with reporters Tuesday morning.

More than 40% of Americans are obese, according to the Centers for Disease Control and Prevention. That percentage is expected to reach 50% by 2030. It’s a serious issue: Obesity can cause or worsen other significant medical conditions, including heart disease, diabetes, strokes and some cancers, and for many patients is doggedly resistant to diet and exercise.

Over the past few years, medications known as GLP-1s have gained widespread attention for their effectiveness in treating obesity. Patients can lose as much as 15% to 25% of their body weight while on the drugs, which work by imitating hormones that communicate fullness when people eat. Research also suggests that GLP-1s may lower the risk of other chronic conditions related to obesity.

Yet despite soaring demand, cost has proved a significant barrier to GLP-1 adoption for many Americans. Even in the U.S.’ pricey prescription drug market, GLP-1s are notably expensive: Annual list prices for the drugs can exceed $11,000.

The price tag has put off many employers and payers from coverage — fewer than 1 in 5 employer-sponsored plans included GLP-1s this year, according to health policy research firm KFF.

Access to the newest anti-obesity drugs has also been patchwork for the 72 million Americans in Medicaid. Currently, only 13 states cover GLP-1s for weight loss, according to KFF.

And the 68 million Americans on Medicare have had zero access to weight loss drugs, given legislation passed two decades ago preventing the program from covering the medications. The CMS allowed some coverage earlier this year, approving Novo Nordisk’s Wegovy for Medicare enrollees who are obese or overweight with cardiovascular disease.

Now, regulators are aiming to get around statutory restrictions entirely by revising the CMS’ interpretation of the law to recognize obesity as a chronic disease instead of a weight management issue.

The changing medical consensus around obesity drove the new interpretation, CMS officials said Tuesday.

“This is not about weight loss per se. This is about treatment of a chronic condition,” Meena Seshamani, the director of Medicare, said on the press call.

The new rule would expand access to the drugs to an estimated 3.4 million people on Medicare and 4 million people in Medicaid, according to a White House press release.

It would do so by allowing obese patients — people with a body mass index of 30 or higher — to qualify for Medicare coverage of weight loss drugs. The expanded coverage would not apply to overweight individuals.

The proposal also reinterprets the Medicaid statute, so anti-obesity drugs can no longer be excluded from the safety-net program.

The move is likely to be popular among U.S. patients — especially since the CMS doesn’t expect the expanded coverage to increase their premiums or out-of-pocket costs, thanks to consumer protection provisions in the Inflation Reduction Act passed in 2022, according to Seshamani.

Some Medicare enrollees currently on GLP-1s could see their out-of-pocket costs fall by as much as 95%, officials said.

However, the expanded coverage could prove expensive for taxpayers. The federal government expects to spend about $25 billion on weight loss drugs in Medicare over 10 years, a figure that could exacerbate existing financial stress on the program.

That sum doesn’t include the impact of any savings from patients’ improved health, though the Congressional Budget Office has estimated savings from GLP-1 coverage will be small, in the ballpark of $50 million to $1 billion each year.

As for Medicaid, the federal government expects to spend $11 billion over ten years, while states will pick up an additional $3.8 billion, according to Medicaid director Dan Tsai.

It’s uncertain how states will react to the proposal, given Medicaid is already often the No. 1 or No. 2 line item on state budgets.
