Some people when they retire at age 65 may be offered a retirement benefit package. You will still need to sign up for Medicare Part A and Part B because you will no longer be working. The calls I receive from individuals ask for a review (no cost) of their retirement benefits compared to Medicare insurance plans offered to the public. Benefits and their costs vary widely from plan to plan. Some retiree plans may also offer discounted vision and dental benefits that are either not offered by Medicare insurance plans or they may offer greater coverage for less money. Some retiree plans act like Medicare supplement plans, other like Medicare Advantage HMO plans. Before accepting or rejecting a retiree plan, make sure you do a comparison of what is available to you to ensure that you make the correct decision for your specific needs.
