Last week, the Food and Drug Administration (FDA) announced the approval of Eli Lilly’s drug tirzepatide for treating obesity. The drug, which will be sold under the name Zepbound for obesity, is already branded as Mounjaro for diabetes treatment. 

While Novo Nordisk’s blockbuster semaglutide drug (sold as Wegovy for obesity and Ozempic for diabetes) works only as a GLP-1 agonist, tirzepatide also targets a second receptor and has been shown to elicit greater weight loss.

Spurred by trial results demonstrating significant health benefits beyond weight loss tied to these drugs, the American Medical Association House of Delegates voted this week to adopt a policy advocating for insurance coverage of GLP-1-based obesity treatments, affirming that it regards obesity as a disease, and that patients left untreated for the condition are at greater risk for serious health consequences.

To date, most insurers and self-funded employers have resisted covering weight loss drugs due to their prices: Zepbound has a list price of $1,060 per month, while Wegovy is priced at around $1,300 per month.

The Gist: We have entered a new era in treating obesity. 

Even with payers and employers dragging their feet over coverage decisions, and Medicare remaining prohibited from covering weight-loss drugs by law, consumer demand for the drugs has been strong enough to outpace supply. Zepbound’s approval will hopefully both improve availability and exert downward pricing pressure. 

While these drugs will undoubtedly contribute to higher healthcare spending in the short term, the long-term benefits of significant weight loss, combined with cardiovascular risk reduction, could lower healthcare costs over the patient’s lifespan—although the payer “holding the bag” for the cost today may not see the return, given that as many as 20 percent of individuals with commercial insurance switch carriers every year.
