You can get on Medicare at age 65. This is regardless of when you choose to collect your Social Security benefits. You can get on Medicare at a younger age if you have been receiving Social Security Disability benefits for two years, or have ALS or ESRD, in some cases.
Typically you can enroll in Medicare when you are 65 - or when you retire past the age of 65. (Unless you have been clinically diagnosed as disabled for at least 2 years - then you can enroll under disability under age 65). IF you are working FULL time past 65, you can take advantage of your employers group health coverage. This may come down to dollars and cents, whether it is advantageous to do so. IF you are past 65 and only working part time - EVEN if your employer offers you health coverage, you must enroll in Medicare or you will be penalized. Penalties from Medicare last a lifetime and do not go away.
