Medicare is the federal health insurance program for all Americans age 65 and over, some younger residents with disabilities, and persons with end stage renal disease. The program covers 3.5 million Texans or 13 percent of the Texas population. (This figure includes 1.2 million Texas residents who have no other form of insurance and 2.4 million who have Medicare combined with some other form of coverage). The program is federally administered. Texas Medicare spending is relatively high compared to other states. With the growing aged and aging populations, there are more voices calling for cost control in this program with some GOP lawmakers advocating for the privatization of Medicare through the use of vouchers to purchase insurance on the private market.
