You will be penalized if you enroll in Medicare outside of your eligibility period

Title: Medicare Enrollment

Article Snip: "...You are eligible to enroll in Medicare three months before you turn 65, the month of your 65th birthday, and three months after the month you turn 65. You will be penalized if you enroll outside of your eligibility period and your options to enroll will be limited. If you miss your eligibility window, you may sign up only during the general enrollment period at the beginning of the year, with few exceptions. And, if Social Security records reflect that you have enrolled late, you will be required to pay a penalty in addition to the monthly premium. The penalty for enrolling late is 10 percent for each year you delay enrollment in Medicare Part B. For most USPS retirees, the premium for Medicare Part B for 2015 is $104.90. Medicare B covers medically-necessary services from doctors and other health care providers, ambulance services, outpatient care, home health care, and some preventative services. For a complete list of covered services, visit www.Medicare.gov. Medicare Part A covers hospitalization and it’s free because you paid for it while you worked for the Postal Service...."
