Medicare ‘Overspent’ by 20% Compared With Costco Prices on Generic Drugs

Medicare spent $2.6 billion more on 184 most common generic drugs compared with Costco member prices for the same prescriptions in 2018, according to a recent research letter published in JAMA Internal Medicine. By analyzing more than 1.4 billion Part D claims, researchers estimated that Medicare spent 13.2% more in 2017 and 20.6% more in 2018 than Costco members paid for 30-day and 90-day prescription fills. In 2018, Medicare spending exceeded the Costco member price on 43.2% of all 30-day and 90-day fills of the generic drugs studied.
