Researchers at the Healthcare Cost Institute compared per-unit prices for the 10 most expensive and 10 most common physician-administered drugs from 2016 to 2020.
For the most commonly used drugs, employer-sponsored plans paid prices up to 3,350 percent higher than Medicare. For midazolam, employer-sponsored plans paid 30 times more than Medicare for the same drug, and they paid 20 times more for ondansetron.
For the most expensive drugs, employer-sponsored plans did not pay as extreme markups, the researchers found. Markups were 54 percent more than Medicare at the high end, and employer-sponsored plans paid similar prices to Medicare rates for some drugs.
