Per-enrollee Medicare spending growth has been low, averaging 1.3 percent over the last five years. In 2014, Medicare expenditures were slightly lower for Part A and Part D, and higher for Part B than previously estimated. Over the next decade, and partially due to the cost-containment provisions in the Affordable Care Act, per-enrollee Medicare spending growth (4.2 percent) is expected to continue to be lower than the overall growth in overall health expenditures (5.1 percent).
In 2014, Medicare provided health insurance coverage to 53.8 million people. Total Medicare expenditures were $613 billion, and income was $599 billion. The average Medicare benefit per enrollee was $12,432, about 2 percent higher than last year. Medicare outlays in 2014 were slightly lower for Part A and Part D, and higher for Part B than previously estimated.
While Part B premiums will be finalized later this year, approximately 70 percent of beneficiaries are expected not to see a premium increase in 2016 because it is projected that there will be no cost-of-living increases in Social Security benefits. The remaining 30 percent of beneficiaries would pay a higher premium based on this projection. These include only individuals who enroll in Part B for the first time in 2016; enrollees who do not receive a Social Security benefit; beneficiaries that are directly billed for their Part B premium; and current enrollees who pay an income related higher premium. Decisions about premium changes will be made in October and depend on a variety of factors.
