Since you want to wait and sign up for Social Security benefits at your full retirement age, you are still entitled to both Medicare Parts A, B and D at age 65. You are eligible to apply for Medicare if you have paid into Social Security for at least 10 years. Medicare will send you a bill every 3 months for the premiums for Part B until you reach your full retirement age. The premium for 2009 is $96.40 per month if your income falls within the limits. Social Security Administration handles Medicare eligibility and enrollment and you can visit their site at www.socialsecurity.gov. You can also call Medicare at 1-800-772-1213 (TTY users should call 1-800-325-0778) regarding enrollment or if you have any questions.
