Medicare advocates say a growing number of older adults are getting ensnared in the program's complex rules, as more seniors return to work or put off leaving their jobs, the Wall Street Journal reports. In January, Rep. Kurt Schrader (D, OR) plans to introduce a bill designed to make it easier for those 65 and older who leave jobs to switch from their employer's group health insurance to Medicare. Among other things, the bill would eliminate the delays that some experience before their Medicare benefits go into effect.
