The Biden administration moved Friday to negotiate the prices Medicare pays for the blockbuster weight-loss drugs Ozempic and Wegovy, medications costing the massive government health program billions of dollars a year.

The Biden administration said Medicare will negotiate discounts with drug companies on 15 drugs prescribed to treat cancer, diabetes and asthma.

The government is expected to pay lower prices for Ozempic and Wegovy starting in 2027. The Trump administration will decide whether to expand coverage for millions of Americans.
