The federal government says the outlook for Medicare funds has improved slightly over the last year.
But, while there has been some improvement, both Medicare and Social Security face long-term financial problems that will grow as more and more baby boomers reach retirement age.
And, a near-term crisis looms in the disability trust fund, which could fall short in just two years.
Medicare and Social Security accounted for 41 percent of all federal spending last year.
Medicare is adding 10,000 new beneficiaries a day as baby boomers reach age 65. But the report said costs per beneficiary were essentially unchanged in 2013, for the second year in a row. That is a contrast with previous years, when both per-person costs and overall enrollment were growing.
