January 10, 2013 – Below is a chart, published by Health and Human Services, that shows how quickly the agency expects Medicare costs to grow over the next two decades. Most of the growth above and beyond overall economic growth has to do with the Medicare population getting older and bigger. That’s what you see in the blue bars. It’s also worth looking at the red bars, which represent the “excess cost growth,” essentially medical prices growing faster than the rest of the economy. This report projects that Medicare cost growth will actually be slower through 2022.
