A Kaiser Family Foundation study has found that ten percent of prescription drugs make up the majority of Medicare drug spending.
According to the study, the 250 top selling drugs, each with one manufacturer and no competitive products on the market, account for 60% of net total Medicare Part D spending. The top 50 selling drugs, also with one manufacturer each and no competitors, account for 80% of total Medicare Part B spending.
This new data strengthens the argument that focusing on negotiating prices for the relatively small number of drugs that make up a disproportionately large amount of Medicare spending could help reduce the costs of prescription drugs to Medicare and the patients who use them.
